This paper presents a mechanism of using rectangular prediction blocks for Intra prediction in the emerging High Efficiency Video Coding (HEVC) standard. In the previous and current video coding standards, Intra predictions have been processed on square blocks, e.g. 16×16, 8×8 and 4×4 pixel blocks H.264/MPEG4 AVC, and 2N×2N or N×N square prediction units (PU) in the current HEVC. In this paper, it...
Hybrid variable length coding (HVLC) was recently proposed as a novel entropy coding scheme for block-based image and video compression, which divides each transform block into low frequency (LF) region and high frequency (HF) region and codes them differently. To take advantage of the clustered nature of the nonzero coefficients in the LF region, a two-dimensional position and one- dimensional amplitude...
