Intra prediction is an important tool in intra-frame video coding to reduce the spatial redundancy. In current coding standard H.265/high-efficiency video coding (HEVC), a copying-based method based on the boundary (or interpolated boundary) reference pixels is used to predict each pixel in the coding block to remove the spatial redundancy. We find that the conventional copying-based method can be...
To reduce the complexity of searching for wedge-based geometry partitions in video coding, we propose a texture-difference based partition line selection approach with a skipping strategy. Applying this approach can reduce the encoding time by 90% while retaining the similar rate-distortion performance to that of exhaustive searching. We also propose a background-compensated prediction scheme to improve...
In this paper, a texture-space geometry partitioning approach is proposed to reduce the computational complexity of searching for geometry partitions for video coding. Additionally, for systems that capture both video and depth data, an enhanced geometry partitioning approach using both texture and depth information is proposed to further improve the partitioning accuracy and reduce the search complexity...
