In 3D-HEVC, a new coding standard of 3D video, Explicit Wedgelet mode within Depth Modelling Modes (DMM) partitions a depth block into two non-rectangular regions using a Wedgelet pattern selected from a Wedgelet lookup table. The Wedgelet lookup table is constructed during both encoder and decoder initialization for each block size ranging from 4×4 to 16×16, while the Wedgelet lookup table consists...
Depth map is a kind of video clip that contains 3D object's depth information, and is an important coding feature in the recently 3D video coding standards, which has been applied for the latest 3D coding approaches, e.g. MV-HEVC and 3D-HEVC. It has been approved that the support of depth map coding can significantly improve the coding performance for 3D videos, and provide more flexibility for 3D...
In High Efficiency Video Coding (HEVC) 3D extension depth modeling mode (DMM) is used in depth intra prediction process. According to the original design, DMM contains four modes that are named as DMM1 to DMM4 respectively, and DMM1 contributes obviously coding gain. In DMM1 mode, DMM1 patterns generation is carried out at the initialization process in encoder and decoder side. In this paper, the...
Current default intra prediction method in the current test model for the next generation video coding standard JCT-VC, Unified Intra Prediction, has up to 33 directional modes and only one non-directional mode, which is Intra DC mode. Having only one non-directional mode is insufficient for maintaining accuracy on prediction units with complex texture. In this contribution, Plane Mode is integrated...
