Abstract

Recently, there have been efforts by the ITU-T VCEG and ISO/IEC MPEG to further improve the compression performance of the High Efficiency Video Coding (HEVC) standard for developing a potential next generation video coding standard. The exploratory codec software of this potential standard includes new coding tools for inter and intra coding. In this paper, we present a new intra prediction mode for lossless intra coding. Our new intra mode derives a prediction filter for each input pixel using its neighboring reconstructed pixels, and applies this filter to the nearest neighboring reconstructed pixels to generate a prediction pixel. The proposed intra mode is demonstrated to improve the performance of the exploratory software for lossless intra coding, yielding a maximum and average bitrate savings of 4.4% and 2.11%, respectively.
