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...
To accurately represent object edges in depth maps, new depth intra prediction modes, namely Depth Modelling Modes (DMMs), are introduced into 3D-HEVC. In the DMMs, a depth block is approximated by a model that partitions the block into two non-rectangular regions, where each region is represented by a constant value referred to as Constant Partition Value (CPV). To code the CPV, a predicted CPV for...
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...
With rapid growth of HD video applications, AVS started HD video profile standardization process in March 2008 and finalized in September 2009. In the late of year 2011, the broadcasting industry standard for HD video compression was developed based on this work and has been recently completed and approved. It uses state-of-the-art coding tools and provides enhanced coding efficiency tools for high-definition...
