Abstract: High-Efficiency Video Coding (HEVC), the state-of-the-art video coding standard by the ITU-T Video Coding Experts Group and the ISO/IEC Moving Picture Experts Group, is presently being prepared to handle the next generation multi-media services. Lossless mode of HEVC is designed to support a variety of lossless compression applications like medical imaging, preservation of artwork, video analytics, etc. The accuracy of the intra prediction can be improved through the incorporation of sample-based prediction strategies which replace the block-based prediction within HEVC. In this work, we propose a sample-based DC intra prediction strategy to enhance the compression efficiency of the HEVC lossless mode. The detailed experimental analysis demonstrates that the proposed method outperforms the HEVC lossless mode of HM16.12 in terms of bit-rate savings by 1.43% and 0.46% on an average for AI-Main and AI-Main10 configurations respectively, without any increase in run-time. � 2017 IEEE.
