DESIGN AND ANALYSIS OF VIDEO COMPRESSION TECHNIQUE USING HEVC INTRA-FRAME CODING

High Efficiency Video Coding (HEVC) is currently being prepared as the newest video coding standard of the ITU-T Video Coding Experts Group and the ISO/IEC Moving Picture Experts Group. The main goal of the HEVC standardization effort is to enable significantly improved compression performance relative to existing standards in the range of 50% bit-rate reduction for equal perceptual video quality. Intra-frame coding is essential in both still image and video coding. In the block-based coding scheme, the spatial redundancy can be removed by utilizing the correlation between the current pixel and its neighboring reconstructed pixels from the differential pulse code modulation (DPCM) in the early video coding standard H.261 to the angular intra prediction in the latest H.265/HEVC [1], different intra prediction schemes are employed. Almost without exception, linear filters are used in these prediction schemes. This paper provides an overview of the Intra-frame coding techniques of the HEVC standard.
