This paper introduces a new intra prediction algorithm that exploits the correlations between the color channels, for the H.264/AVC intra coding. The main idea is to use the weighted sum of neighboring pixels as a new chroma prediction tool, where the weighting coefficients are determined considering the inter-channel correlations. Specifically the weighting coefficients are determined under the assumption...
In recent video applications such as MPEG or H.264/AVC, the bandwidth requirement for frame memory has become one of the most critical problems. Compressing pixel data before storing in off-chip frame memory is required to alleviate this problem. In this paper, we propose a lossless frame memory recompression scheme including 1) a lossless pixel compression algorithm, 2) an efficient address table...
This paper proposes a motion vector (MV) prediction algorithm for increasing the gain of multiview video coding (MVC). In the conventional MVC algorithms, the main feature that brings coding gain is the interview MV estimation and compensation in anchor frames. Although all the other frames (non-anchor frames) also consider both temporal and interview MVs, the interview MVs are usually outnumbered...
