Abstract
High Efficiency Video Coding (HEVC) Screen Content Coding (SCC) has been standardized for the screen-captured contents. Because many areas are composed of the texts and lines featuring non-smooth textures, the traditional intra prediction is not suitable for those areas. Several newly coding tools, such as the palette mode, intra block copy, string matching mode, uni-color intra mode, bi-color intra mode, and multi-color intra mode, were developed to address the issues during the joint meetings of MPEG and VCEG from 2014 to 2015. ITRI had contributed many techniques over the uni-/bi-/multi-color intra modes to improve compression performance, and coordinated the core experiment activities of the uni-/bi-/multi-color intra modes to study the performance under the HEVC SCC standard draft text 1. The concept of the color intra modes is to select a few samples out of the neighboring coding units to predict the pixels inside the current coding unit. In this talk, I will give you an elaboration over the uni-/bi-/multi-color intra modes.
