Abstract

This paper proposes a new fractal coding algorithm for 3D free multi-view HD video based on the monocular HD video fractal coding system. This algorithm combines not only motion compensation prediction and disparity compensation prediction, but also inter-component prediction, it can effectively remove redundancy. In addition, for the special features of the depth map different from the texture map, a non-rectangular block segmentation prediction mode is designed to reduce the distortion of the object edges in the depth map. Using the correlation between the depth map and the corresponding color texture map, the pattern pre-selection algorithm is designed to avoid unnecessary prediction process. The non-rectangular block split mode or the legacy intra prediction mode is adaptively selected.The experimental results show that the fractal 3D free multi-view HD video coding system proposed in this paper is superior to the MVC standard JMVC8.5 in coding performance. It reduces the coding complexity and coding rate of three-dimensional free multi-view HD video and improves coding efficiency. The code rate is reduced by an average of 67.90%, the PSNR is increased by an average of 9.15 dB, and the coding time is reduced by an average of 23.35%.
