In this paper, we propose a novel segmentation-based intra prediction coding scheme for low-bitrate video coding. Different coding schemes are separately designed for the luma and chroma components in our proposed method. The traditional block-based coding scheme is still used for the luma components, and the segmentation-based coding scheme is developed for the chroma components. The segmentation...
Multiple reference frames motion compensation is one of the new features adopted in H.264/AVC to improve the coding efficiency of inter frames. However, the computational complexity of multi-reference frames motion estimation (MRME) is increased in proportion to the number of searched reference frames. This paper presents a novel scheme to reduce the complexity of MRME. In order to speed up the MRME...
Directional intra prediction is one of the new features adopted in H.264/AVC standard. In contrast to some previous coding standards, the prediction is performed in the spatial domain. Two types of intra prediction for luma - Intra16times16 and Intra4times4 are included in each profile. For high profile, there is an additional type - Intra8times8. Intra 16x16 and Intra4times4 support four and nine...
