Abstract

Chroma-keying is a technique for separating objects from the original scene to be integrated in another scene. Usually, it is performed using a uniform colored background. By detecting the color of the background, the matte is generated. This matte is used as a mask that specifies which pixels are related to the interesting object and which pixels are related to the background. Chroma-keying is used in film industry for integrating actors with other background that may be real or virtual one. Actors are prohibited from wearing clothes that have colors that close to the uniform color of the background. Depth sensors, such as Microsoft Kinect, are used for determining the depth of objects in the scene. Many techniques were presented that use depth sensors for separating interesting objects form the original scene using their depth information. However, depth sensor's accuracy is still limited. Depth sensors can be used in addition to the image processing for removing chroma-keying's limitations and getting a better accuracy more than using a standalone depth sensor for separating objects from the scene.
