Improved CABAC for Lossless Video Compression

Efficient residual data coding in CABAC for HEVC lossless video compression

After the development of the next generation video coding standard, referred to as high efficiency video coding (HEVC), the joint collaborative team of the ITU-T video coding experts group and the ISO/IEC moving picture experts group has now also standardized a lossless extension of such a standard. HEVC was originally designed for lossy video compression, thus, not ideal for lossless video com...

Efficient Differential Pixel Value Coding in CABAC for H.264/AVC Lossless Video Compression

Since context-based adaptive binary arithmetic coding (CABAC) as the entropy coding method in H.264/AVC was originally designed for lossy video compression, it is inappropriate for lossless video compression. Based on the fact that there are statistical differences of residual data between lossy and lossless video compression, we propose an efficient differential pixel value coding method in CA...

Lossless compression of video sequences

In this paper we investigate lossless compression schemes for video sequences A simple adaptive prediction scheme is presented that exploits temporal correlations or spectral correlations in addition to spatial correlations It is seen that even with motion compensation schemes that utilize only temporal correlations do not perform signif icantly better than schemes that utilize only spectral co...

Lossless Compression of Video Using Motion Compensation

An Improved Hierarchical Lossless Text Compression Algorithm

Several improvements to the Bugajski-Russo N-gram algorithm are proposed. When applied to English text these result in an algorithm with comparable complexity and approximately 10 to 30% less rate than the commonly used COMPRESS algorithm. I. The N-Gram Algorithm The N-gram algorithm of Bugajski and Russo [1] is a hierarchical dictionary-type universal lossless source coder for a finite source ...
