Abstract: The present disclosure relates to the technical field of video coding. Implementations herein provide methods for fast 3D video coding for high efficiency video coding HEVC. The methods speed up the view synthesis process during the rate distortion optimization for depth coding based on texture flatness. The implementations include extracting coding information from textures, analyzing luminance regularity among pixels from flat texture regions based on statistical method, judging the flat texture regions using the luminance regularity for depth maps and terminating the flat texture block's view synthesis process when processing rate distortion optimization. Compared to original pixel-by-pixel rendering methods, the implementations reduce coding time without causing significant performance loss.

Abstract translation: 本公开涉及视频编码的技术领域。 本文的实现提供了用于高效率视频编码HEVC的快速3D视频编码的方法。 该方法在基于纹理平坦度的深度编码速率失真优化中加快了视图合成过程。 这些实现包括从纹理提取编码信息，基于统计方法分析来自平坦纹理区域的像素之间的亮度规律性，使用深度图的亮度规则来判断平面纹理区域，并且在处理速率失真优化时终止平面纹理块的视图合成处理。 与原始的逐像素渲染方法相比，这些实现减少了编码时间，而不会导致显着的性能损失。
