Edges based Intra-prediction in High Efficiency Video Coding (HEVC) Standard

HEVC (H.265) standard is the latest enhanced video coding standard which was planned to improve the rendered specifications of its preceding standard MPEG-4 (H.264). The main goal of the HEVC standardization effort is to enable significantly improved compression performance relative to existing standard H.264. For similar video quality, HEVC bitstreams consume only about half of the bitrate compare to previous standard H.264. HEVC gives higher compression comparing with previous standard H.264 because of its new features like quadtree structure, more directional intra-prediction modes. In this paper, intra-prediction for equal block sizes and variable block size are implemented for luminance component of different video sequences. Luminance component is important for brightness information. For variable block size canny edge detection method is used. HEVC gives better PSNR compare to H.264. HEVC suitable for resolutions up to Ultra High Definition (UHD) video coding in the future.
