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...
This paper presents an improved Segment-wise Direct Component (DC) Coding (SDC) for High Efficiency Video Coding (HEVC) intra prediction of depth maps. In the current 3D-HEVC, predicted DC in the SDC for HEVC intra prediction modes is calculated as the average of four corner samples in a predicted block. However, this method may introduce errors when SDC employs depth lookup table (DLT). To reduce...
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...
