Transform-based coding is a technique that is widely used in image and video compression, where compression is achieved via decomposing each component block or patch over a complete dictionary known to provide compaction. Recently, there has been a growing interest in using basis selection algorithms for signal approximation and compression. Signal approximation using a linear combination of basis...
This paper proposes a new intra coding scheme, known as short distance intra prediction (SDIP), for high efficiency video coding (HEVC) standardization work. The proposed method is based on the quadtree unit structure of HEVC. By splitting a coding unit into nonsquare units for coding and reconstruction, and therefore shortening the distances between the predicted and the reference samples, the accuracy...
