点评：一种多视点视频的处理方法，由于本发明方法将颜色校正处理过程嵌入到多视点视频编码处理过程中，与典型的先进行颜色校正再进行视点视频编码的方法相比，大大提高了多视点视频编码的编码性能；由于本发明是利用宏块的编码模式信息来进行前背景分离处理，与现有的利用视差估计或区域分割进行前背景分离的方法相比，本发明方法的前背景分离处理快速而又精确；此外，本发明利用背景信息来进行颜色校正，与在全局的图像间或在最相似的区域间进行颜色传递的方法相比，有利于获得一致的参考平面，更加符合相机的成像原理，提高了多视点视频颜色校正的精度。

Comment: The invention discloses a processing method applied to a multi-view video. Since a color correction process is embedded into a multi-view video encoding process, compared with a typical method that the view video encoding is carried out after the color is corrected, the method of the invention significantly improves the encoding performance of the multi-view video encoding. In addition, since the encoding mode information of a macro block is utilized for the separation processing of a front background, compared with the existing method that the front background is separated by utilizing parallax estimation or region-dependent segmentation, the method of the invention can ensure the fast and precise separation processing of the front background. Furthermore, the method of the invention utilizes background information to correct the color, compared with a method that the color is transferred between overall images or between the most similar regions, the method benefits to obtaining a corresponding reference plane and better comply with the imaging principle of a camera, thus improving the precision of the color correction of the multi-view video.
