Claim:
1. A method for high efficiency video coding (HEVC) 3D video coding, the method comprising: (1.1) extracting coding information from coded textures, the coding information including a block size represented by n×n, a coding mode represented by Mode and an individual pixel luminance value in reconstructed blocks represented by Y; (1.2) analyzing luminance regularity among pixels from flat texture regions, selecting blocks of which the Mode is IntraDC as flat texture blocks using the coding information obtained in step (1.1), storing sizes and pixel luminance values of the flat texture blocks, and analyzing the luminance regularity among the pixels from the flat texture blocks based on a predetermined statistical method to set a threshold represented by T; (1.3) dividing a current depth block into l flat lines and m non-flat lines using the threshold T obtained in step (1.2) during a view synthesis process of rate distortion optimization for depth map coding to obtain flat line and non-flat line division results; and (1.4) terminating the view synthesis process for the pixels in flat lines and decreasing high coding complexity caused by a pixel-by-pixel view synthesis process using the division results obtained in step (1.3).
