3D video has raised great interest in the last decade and currently a new 3D video coding standard, known as 3D video coding extension of High Efficiency Video Coding (3D-HEVC), has been developed. The standard investigates the coding of multiview video plus depth, which consists of texture videos and depth videos of multiple views. Depth video, as a description of geometry information of a scene,...
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 proposes a fast mode decision algorithm for 3D High Efficiency Video Coding (3D-HEVC) depth intra coding. In the current 3D-HEVC design, it is observed that for most of the cases, full Rate-Distortion (RD) cost search of Bi-partition mode could be skipped since most coding units (CUs) of depth map are very flat or smooth while Bi-partition modes are designed for CUs with edge or sharp transition...
