Angular-based Residual Signal Coding of Intra Depth Map in 3D-HEVC
○ホウアリ サビリン・河村 圭・内藤 整（KDDI研）
Coding of depth map data in 3D-HEVC utilizes depth look-up table (DLT) to reduce the residual signal of depth map which is constructed based on the depth structure of a sequence. The resulting table is then stored in the bitstream, thus additional memory allocation becomes necessary. To overcome this problem, we propose a method of complementing the DLT with comparable arithmetic function by mapping the residual data in intra mode into two nonzero integer signals according to the area of the prediction mode of the current luma block. Experiment results in HTM10.0 provide BD-rate gain up to 0.031% and up to 3% reduced coding time.
