Abstract:

The vast amount of user uploaded visual content available online makes automated visual classification a critical research problem. While existing studies for visual classification mainly focus on recognition of generic objects such as vehicles, plants, food and animals, recently, studies have also been presented for exploring a more challenging research problem, fine grained object classification, aiming to distinguish fine subcategories within coarse object categories, such as types of vehicles, flowers and kinds of food. Here, another fine grained categorization problem important for multimedia applications, categorizing in-building scenes and their architectural styles, is attempted which will be beneficial for applications related to real estate and interior decoration. In-building scenes are divided into five coarse categories; kitchen, bathroom, living room, bedroom and dining room. As fine categories, each in-building scene has been assigned an architectural style such as Asian, Contemporary, Victorian, Rustic and Scandinavian. On a database consisting of a large number of in-building images, descriptive patterns corresponding to types of scenes and specific architectural styles are learned globally by utilizing deep convolutional neural network based models that have proven success in visual categorization. Moreover, local scene elements and objects which provide further clues for identifying architectural styles are discovered: Scene objects with unique architectural style characteristics carry more discriminative power, whereas co-existing objects visible among various types of scenes are less discriminative. As potential useful applications, several scenarios for classification and retrieval of in-building images are investigated. Experiments show that using only the learned deep representations are effective in identifying scene types while they perform poorly for architectural styles. Nonetheless, revealing key local scene objects ameliorates their performance for both classification and retrieval tasks for architectural styles.

Abstract:

This presentation describes the development and use of the art of encephalography in a new and more advanced way, whereby this qualitative tool where large quantities of brain data images are processed and converted into brain dynamics movie and then displayed for the purpose of visual discrimination associated with the different brain cognitive states, as well as the different stages of cognitive processes related to the cycle of creation of knowledge and meaning. The methodology we present is inspired by the art of encephalography, where this art is enhanced from the mere plotting of brain signals in the time domain to spatio-temporal frames that when presented in a sequence of plots, produces a brain dynamics movie which allows to visualize different patterns of behavior in different conditions produced by different stimuli based on experimental data. By careful observation of each of these movies, we learn to identify different structures and visual patterns where large-scale synchronizations and de-synchronizations are observed across different frequency bands. These movies also allow us to explore the temporal evolution of these spatial brain patterns where we can identify the different stages in the manifestation of the hypothesized cycle of creation of knowledge and meaning. We conjecture that movie viewing, will allow a better understanding of learning and adaptation. In summary, we can say that viewing brain dynamics movies will allow a significant impression of: Brain events for different measurement; brain events across bands and; the different stages of the cycle of creation of knowledge and meaning. The research team at The Embassy of Peace in Whitianga, New Zealand accomplished this work in close collaboration with Walter J. Freeman and Robert Kozma.

Takayoshi Iitsuka completed his Master's degree in Science and Technology at University of Tsukuba in Japan. From 1983 to 2003, he was a Researcher and Manager of optimizing and parallelizing compiler for supercomputers in Central Research Laboratory and Systems Development Laboratory of Hitachi. From 2003 to 2015, he was in strategy and planning department of several IT divisions. He retired Hitachi in October 2015 and started study and research of Artificial Intelligence in May 2016. In October, he achieved top position of Montezuma’s revenge in OpenAI gym. His current research interests include Deep Learning, Deep Reinforcement Learning and Artificial General Intelligence based on whole brain architecture.

Abstract:

Games with little chance of scoring such as Montezuma’s revenge are difficult for Deep Reinforcement Learning (DRL) because there is little chance to train Neural Network (NN), i.e. no reward, no learning. DeepMind indicated that pseudo-count based pseudo-reward is effective for learning of games with little chance of scoring. They achieved over 3000 points in Montezuma’s revenge by combination with Double-DQN. On contrary, its average score was only 273.70 point in combination with A3C (it is called A3C+). A3C is very fast training method and getting high score with A3C+ is important. I propose new training methods: Training Long History on Real Reward (TLHoRR) and Diverse Hyper Parameters in Threads (DHPT) for combination with A3C+. TLHoRR trains NN with long history just before getting score only when game environment returns real reward i.e. training length by real reward is over 10 times longer than that of pseudo-reward. This is inspired by reinforcement of learning with dopamine in human brain. In this case, real score is very valuable reward in brain and TLHoRR strongly trains NN like dopamine does. DHPT changes hyper parameters of learning in each thread and make diversity in threads actions. DHPT was very effective for stability of training by A3C+. Without DHPT, average score is not recovered from zero when it is dropped to zero. With TLHoRR and DHPT in combination with A3C+, average score of Montezuma’s revenge almost reached 2000 points. This combination made exploration of game state better than that of DeepMinds’s paper. In Montezuma’s revenge, five rooms are newly visited by TLHoRR and DHPT; they were not visited by DeepMinds’s pseudo-count based pseudo-reward only. Furthermore, with TLHoRR and DHPT in combination with A3C+, I got and kept top position in Montezuma’s revenge in OpenAI gym environment from October 2016 to March 2017.

Abstract:

Social media play a significant role among younger generations and students. They use it to communicate with the public, spread news, and share their thoughts using different content forms like text, audio, image, and video. Multimedia makes the transfer of information much easier. This paper details the results of a semester-long experiment that detect the effects of integrating Twitter with e-learning tools on the education process. More specifically, the experiment studies the ability to enhance the students’ understanding of the taught material and improve communication between the students and the instructor. The study was done in participation with sophomore SEU students taking CS141 (computer programming) and IT241 (operating systems) courses for computing and informatics majors. The study was conducted using the Twitter account @seugeeks. A total of 114 subscribers followed the account during the semester of the study. Twitter account was used for many activities, such as announcements, video tutorials, questions, and discussions. To assess the impact of using twitter in the teaching process, an online survey was published at the conclusion of the semester. A total of 39 students participated in the survey. The results reflected that all participants have twitter account, and the majority of them (65%) were using it for more than three years. Statistical analysis of Likert scale data revealed positive results of utilizing Twitter in the learning process. Both students and instructor were able to communicate with each other in an easier way creating a collaborative environment. In fact, 96% of the participants supported utilizing the same methodology with other courses. In conclusion, this study provides evidence that Twitter is a useful tool in the educational process especially when different forms of media are combined. The study demonstrates Twitter’s ability to provide a collaborative platform for both faculty and students.

Abstract:

We proposed a technique of obtaining the visually perceived positions of virtual objects presented in front of the screens of 3-D displays, and evaluated it. Applications where users’ own bodies, which are actually seen by users unlike video captured images, interact with virtual objects are attractive applications of 3-D displays. Users expect interactions to be executed when their bodies are seen at the same positions of virtual objects because it is natural for them. Executing interactions when users’ bodies are at the visually perceived positions of virtual objects is the crucial requirement to interactions between the bodies and objects. Conventional techniques execute interaction when users’ bodies are at the positions calculated from binocular disparity of virtual objects. However, the visually perceived positions often differ from the positions calculated from binocular disparity, so that conventional techniques make it difficult to meet the requirement. In contrast to conventional techniques, the proposed technique can meet the requirement by obtaining the visually perceived positions of virtual objects from body movements. According to previous studies on body movements, the velocity of reaching movements as a function of time follows a bell curve. In the proposed technique, the velocity of reaching movements when users reach out to virtual objects is first fitted into a Gaussian function. The final positions of reaching movements are then obtained based on the fitted functions before the movements are finished because virtual objects are seen there. Therefore, the requirement is fulfilled by executing interactions when users’ bodies are at the positions obtained in last step. In the evaluation, we demonstrated the feasibility of the proposed technique by examining the accuracy and precision of the positions obtained with the proposed technique. We also demonstrated the usefulness of the proposed technique by examining the exactness of interaction executed with the proposed technique.

Abstract:

Target tracking, which aims at detecting the position of a moving object from video sequences, is a challenging research topic in computer vision. Obstacles in tracking targets can grow due to quick target motion, changing appearance patterns of target and scene, non-rigid target structures, dynamic illumination, inter-target and target-to-scene occlusions, and multi-target confusion. As selection of features affects the tracking results, it is eventful to select right features. Feature selection is closely related to the target representation. A target shape can be represented by a primitive geometric shape including rectangle, ellipse, circle, square, triangle, and point [1]. The efforts of tracking targets or objects in videos as efficient as possible are not new [1, 2, 3, 4]. A vast majority of the existing algorithms primarily differ in the way they use image features and model motion, appearance and shape of the target. In this discussion, we will discuss how to track unknown number of individual targets in videos by leveraging a spatiotemporal motion model of the movers. We will address our innovative idea [4] of how to extract the candidate regions, irrespective of movers' number in the scenes, from the silhouetted structures of movers' pixels. Silhouettes of movers obtained on capturing the local spatiotemporal motion patterns of movers, we can generate candidate regions in the candidate frames in a reflex manner. Candidate frame means a frame where a target template would be matched with one of its available movers. Weak candidate regions are deleted with the help of phase-correlation technique, while strong candidate regions are fed into a combined tracking algorithm of Hungarian process and Kalman filter. Since targets are searched in the strong candidate regions only, some well-established concepts (e.g., integral images [5] and brute force) are left out. Henceforth, search process gets super rapid as compared to brute force since comparative runtime reduced from O(n!) to O(n³) with problem size n. Complete trajectories of individual targets in 3D space are resulted in asymptotic runtime of O(n³). Figure 1 shows a sample output of our framework.

Abstract:

Level: Survey, research issues

Theme: Quality of Service, Next generation networks, wireless networks

Summary: Emerging Internet Quality of Service (QoS) mechanisms are expected to enable wide spread use of real time services such as VoIP and videoconferencing. The "best effort" Internet delivery cannot be used for the new multimedia applications. New technologies and new standards are necessary to offer Quality of Service (QoS) for these multimedia applications. Therefore new communication architectures integrate mechanisms allowing guaranteed QoS services as well as high rate communications.

The service level agreement with a mobile Internet user is hard to satisfy, since there may not be enough resources available in some parts of the network the mobile user is moving into. The emerging Internet QoS architectures, differentiated services and integrated services, do not consider user mobility. QoS mechanisms enforce a differentiated sharing of bandwidth among services and users. Thus, there must be mechanisms available to identify traffic flows with different QoS parameters, and to make it possible to charge the users based on requested quality. The integration of fixed and mobile wireless access into IP networks presents a cost effective and efficient way to provide seamless end-to-end connectivity and ubiquitous access in a market where the demand for mobile Internet services has grown rapidly and predicted to generate billions of dollars in revenue.

It covers to the issues of QoS provisioning in heterogeneous networks and Internet access over future wireless networks. It discusses the characteristics of the Internet, mobility and QoS provisioning in wireless and mobile IP networks. This tutorial also covers routing, security, baseline architecture of the inter-networking protocols and end to end traffic management issues.

Abstract:

Multi-view video refers to a composite video stream generated by simultaneous capture from multiple cameras covering different portions, or views, of a scene. The Joint Video Team (JVT) has developed H.264/Multi-view Video Coding (MVC) to enhance the compression efficiency for multi-view video. Streaming of multiview video demands high bandwidth even after encoding. Any loss during transmission will have effect on the real-time quality of experience (QoE) of the end user due to the prediction structure used in H.264/MVC encoder. We will address the challenges in delivering MVC video and introduce MVC delivery technologies in both the traditional client/server based model and peer-to-peer (P2P) based model. 

In the traditional client/server based streaming scenario, we have investigated the impacts of network fluctuations (e.g. packet losses) on the quality of streamed MVC video. The test results reveal unexpected differences in video quality amongst the streamed views. An MVC interleaving method is proposed to address this problem, which preferentially transmits the Network Abstraction Layer Unit (NALUs) with higher importance levels for decoding pictures. It reduces transmission errors on more important NALUs and hence enhances the streamed quality of different views.

In the P2P delivery scenario, we have investigated the optimisation problem of maximising outbound bandwidth utilisation of the peers in order to reduce bandwidth usage of the servers. The MVC layer dependency creates challenges in video layer sharing amongst the peers. The layers that can be shared between peers are limited by the layer dependency. A Bit-Torrent based layer-dependency-aware MVC video streaming system has been proposed and evaluated.

Abstract:

The rapid advances in electronic devices, digital imaging, information technology, computer systems and networks in recent years have stimulated the explosive growth of multimedia computing with diverse applications to different areas including medical service and healthcare. Equipped with various multimedia tools, techniques and services, computerized healthcare is emerging as an ever-increasing important multidisciplinary area which offers tremendous opportunities and excellent facilities to doctors, healthcare professionals and other eligible users to enhance performance by fully utilizing the rich health related multimedia data for effective decision making.  Although the current achievements are exciting and the results can be powerful, it remains a challenging task to manage diversity of health related multimedia data on an open heterogeneous landscape (multi-modality, big volume, mobility, time series) efficiently, accurately, reliably and cost-effectively.

This talk presents a general multimedia-based framework to tackle the crucial issues on personalized healthcare. The new medical record e-book structure is proposed to facilitate flexible management of high-dimensional medical data on an open heterogeneous landscape. More specifically, our approach is revolved around three key aspects: 1) multimedia-based medical data management in the context of multi-modality, big volume, mobility and time series; 2) feature selection and fusion of high-dimensional medical data analysis and evaluation with quantitative measurement; 3) classification and decision support scheme for convenient, reliable, efficient and cost effective medical services. A prototype of smart mobile healthcare is developed to demonstrate the feasibility and potentials of the new solution which bridges the gap between data management, medical applications and multimedia computing in a robust environment.

Abstract:

In recent years, there has been a tremendous increase in video capturing devices, which led to large personal and corporate digital video archives. This huge volume of video data became a source of inspiration for the development of vast numbers of applications such as visual surveillance, multimedia recommender systems, and context-aware advertising. The heterogeneity of video data, higher storage, processing cost, and communication requirements demand for a system that can efficiently manage and store huge amount of video data, while providing user-friendly access to stored data at the same time. To address this problem, multimedia summarization schemes have been proposed. Multimedia summarization refers to the extraction of keyframes, identifying most important and pertinent content. In various applications, video summarization can be conducted from the perspective of information prioritization, ranking chosen keyframes relative to their ability to describe the content of the video. A good video summary improves the effectiveness and efficiency of video archiving, cataloging, indexing, as well as increasing the usability of stored videos.

 In this talk, video summarization in general and specifically in the context of prioritization (VSP) will be discussed. Varieties of algorithms, ranging from resource-conscious summarization framework to visual attention-based summarization methods are proposed. Four different VSP techniques are also proposed. The first summarization method is based on a light-weight visual attention model to efficiently extract diagnostically relevant keyframes from wireless capsule endoscopy videos. The second scheme proposes a resource-conscious summarization framework to manage remote sensing wireless capsule video data. The summarization is based on redundancy removal and classification of non-redundant frames into informative and non-informative frames. This framework utilizes cloud resources by adaptively offloading summarization tasks from mobile to cloud. The third and fourth proposed methods explore summarization in the context of prioritization in two different domains: 1) prioritization of brain magnetic resonance images; and 2) saliency-directed prioritization of visual data in wireless surveillance networks.

Abstract:

Super-resolution reconstruction (SRR) is an effective means to address the problem of insufficient image resolution in imaging applications. Existing SRR algorithms use well-focused images and ignore the value of defocused images generated by the imaging system during focusing. The starting point of the present study is to treat a defocused image as distribution and accumulation of scene information among different pixels of the detector, as well as a valid observation of the imaged subject; defocused images are the result of blurring a corresponding high resolution (HR) image using a point spread function (PSF) followed by downsampling. From this starting point, we used multiple defocused images to build an observation model for HR images and propose a SRR algorithm to approach the HR images. We have developed an image degradation model by analyzing optical lens imaging, used the particle swarm optimization (PSO) algorithm to estimate the PSF of the HR image, and used compressed sensing (CS) theory to implement SRR based on the non-coherent characteristics of multiple defocused images. Experiments demonstrate that our method can be used to obtain more information about details of a scene and improve the visual effect without adding any hardware facilities, improving the recognition and interpretation of the image subject.

Abstract:

Theoretical Background: In the linguistics literature on verbal semantic integration, the N400 effect refers to the fact that unexpected words will cause very low level of negative potentials in brainwave measures around 400ms(milli-seconds) after repeated presented settings and the P600 effect refers to the fact the unexpected words will cause very high level of positive potentials around 600ms.

Methods: Research literature on the video summarization indicates importance of the development of an un-obtrusive method of gathering external information of video users (Z. Lu and K. Grauman,, 2013; W. Ren and Y. Zhu,, 2008; A. Porselvi and S. Gunasundari, 2013). The analysis of event-related potentials (ERP) is such a method which extracts only a result of reaction with respect to certain stimuli from the brain waves.

Findings and Implications: We observed greater maximum potentials at the left prefrontal cortex (FP1, t = 6.930, p = 0.013), the left, right, and middle central lobes (C3, t = 4.670, p = 0.039; Cz, t = 9.818, p = 0.004; C4, t = 10.549 , p = 0.003), and the right and middle frontal-central lobes (FC4, t = 7.370, p = 0.011; FCz, t = 6.541, p = 0.016) of brain wave responses to topic-relevant shots. The right parietal and right temporal-parietal lobes (P8, t = 4.483, p =0.043; TP8, t = 5.326, p = 0.028). It is indisputable to further attempt this sort of ERP analysis of the EEG data during continuous viewing session using topic-relevance ratings from still image testing. Still, the surprisingly large effect of N400 and P600 at prefrontal lobe are asking for further refinement in the future experimental design.

Importance: We developed a method to import time code of video presentation to the EEG data with the topic-relevant information from ratings of topic-relevance for still-image captured from visual shots which were included in the videos. SNR(signal-to-noise ratio) of ERP analysis for the visual shots are about 12.2 well fit in the rage of 10-14 as professional consultant recommended for SNR.

Abstract:

Supervised retrieval model has been widely used in the field of computer vision and its high-quality result is supported by enough learning instances  .However, in the process of experiments, it’s difficult to offer enough learning instances for each category. Especially for some special categories, the drawback is more obvious. So how to solve the problem has become one challenging problem.

For this problem, we proposed one new model that can use candidate learning instances to replace the learning instances (In this paper, we mainly consider positive instances). On the one hand, the improved spatial pyramid matching function contributes to retrieve candidate learning instances effectively. On the other hand, an optimized SVM model make the most of candidate learning instances to keep the accuracy of retrieval. At last, we did enough groups of experiments using the new model. The experimental results show that our new model not only can reduce the number of learning instances but also can keep the high-quality of retrieval.

Abstract:

This study focused on how to enhance the interactivity and usefulness of augmented reality (AR) by integrating manipulative interactive tools with a real-world environment. A manipulative AR (MAR) system, which included 3D interactive models and manipulative aids, was designed and developed to teach the unit “Understanding Weather” in a natural science course, and to bridge a formal learning environment (i.e. school), non-formal (i.e. at a museum), and informal learning environments (i.e. home). Sixty-four sixth-grade students (12–13 years old) from four classes in Taipei City were enrolled in a seven-week general studies course entitled “Natural and Life Science and Technology”, and they were divided into an experimental group (31 students who used the MAR system) and a control group (33 students who used multimedia teaching resources). After seven weeks of experiments, the results revealed that integrating the MAR system into inquiry-based field study made a greater positive impact on the students' academic achievement and motivation compared to the multimedia teaching resources installed on a tablet PC. Additionally, there were two interesting findings: (1) the MAR system offered effective learning materials relative to the multimedia teaching resources and (2) manipulative aids were an effective learning tool for interactivity and usefulness of AR. Besides, there were two meaningful suggestions associated with designing and developing the AR educational system for future researchers and designers, namely make it easy to use and include manipulative aids.

Abstract:

As a new theory of signal sampling, sparse representation derived from compressed sensing, which is obviously different from Nyquist sampling theory. More and more image classification methods based on sparse representation have been proved to be effectively used in different fields, such as face recognition, hyper spectral image classification, handwriting recognition, medical image processing, etc. Image classification methods based on sparse representation has become a hotspot of research topic in recent years. Not only the research institutes, but also the governments and the militaries have invested lots of energy and finance in this attractive task. In this presentation, we intend to review its history and development tendency, and reveal our latest research progress on sparse representation for image classification.

Abstract:

We propose a novel near-duplicate document image matching approach. Some keypoints are first detected from the image using the difference-of-Gaussian function. We then present a clustering method, based on which the keypoints are clustered into several groups. The number of clusters is determined automatically according to the distributions of the keypoints.  Afterwards, a graph is generated whose nodes correspond to the obtained clusters and the edges describe the relationships between two clusters. Consequently, the problem of image matching is transformed to graph matching. To compute the similarity between two graphs, we build their association graph and then find the maximum weight clique. A thorough evaluation of the performance of the proposed approach is conducted on two different datasets. Promising experimental results demonstrate the effectiveness and validity of this method.

Abstract:

Statement of the Problem: Augmented Reality (AR) is a view that integrates the real world imagery with computer generated sounds, images or 3D objects. It has been possible by AR to place 3D reconstructions of buildings, which have been subject to wear and tear of thousands of years, on a historic site. In this way, cultural heritage sites can be better explained and handed on to future generations. Physical reconstruction in ruined cultural heritage sites can be financially costly and time consuming. In addition, site can be damaged during physical reconstruction. With state-of-art AR technology, 3D models can be placed in-situ without any damage, while increasing the appeal of the area for tourists and enthusiastic students.

The aim of this study is augmenting the video images received from mobile devices or drones with 3D models of Roman Bath which is one of the important cultural heritage sites in Ankara, Turkey.

Methodology & Theoretical Orientation: 3D model of Roman Bath were generated using reconstruction images drawn by expert archaeologists. Using Unity 3D Game Engine, this model was overlaid to the camera stream which is received from mobile devices such as mobile phones and tablets. The location services provided by these mobile devices were also used to place the model using actual GPS locations.  Furthermore, an AR application was developed for drones to augment camera streams from a top-view, (Figure 1).

Findings: The developed application allows the users to display the models augmented on the camera view. The use of drones in this study brings a new dimension to Augmented Reality by adding a third eye to the user. We name this approach as ‘Distant Augmented Reality’.

Conclusion & Significance: The authors expect that such applications not only provide an entertaining way to learn about history but also preserve cultural heritage sites.

Abstract:

Camera pose estimation with respect to target scenes is an important technology for superimposing virtual information in augmented reality. However, it is difficult to estimate the camera pose for all possible view angles because feature descriptors such as SIFT are not completely invariant from every perspective. We propose a novel method of robust camera pose estimation using multiple feature descriptor databases generated for each partitioned viewpoint in which the feature descriptor of each keypoint can be almost invariant. Our method estimates the viewpoint class for each input image using deep learning based on the set of training images prepared for each viewpoint class.  We introduce two ways of preparing those images for deep learning and generating databases. In the first method, images are generated by Projection matrix to learn more robustly in the environment by changing those background. The second method uses real images to learn the entire environment around the plane pattern. Through the evaluation result, we confirmed that the number of the correct matches increased and the accuracy of camera pose estimation was improved compared to the conventional method.

Furthermore, we are trying on applying the concept of Viewpoint Class to the field of Object Recognition recently. Object recognition is one of the major research fields in computer vision and has been applied to various fields. In general, conventional methods are not robust in the obstacle and have a problem such that the accuracy is decreased when the camera stagnates at a poor position to the target object. We propose a novel method of object recognition that can be carried in real time by equally dividing the viewpoint around each object in the scene and impartially integrating the Convolutional Neural Network (CNN) outputs from each Viewpoint Class (See Image). We confirmed its effectiveness through experiments.
