Abstract: Multi-view video is a kind of video sequence taken by a set of cameras. Generally, it is difficult for the performance parameter of each camera to totally agree with each other, which consequently causes color differences among video images of different viewpoints. A new color compensation model is proposed for the Multi-View Video Coding（MVC）, which can efficiently use information of inter-view of mutual independent coding to reduce the color mismatch caused by multi-arrays of camera shooting. This method can establish color compensation model in RGB color space and furthermore can extend it to YCbCr color space to suit for present video code standard. Compared to the previous inter-view reference images, the modified inter-view reference pictures are more similar to the present code image which consequently improves the coding efficiency of MVC. Moreover, the color compensation parameter can be derived in both encoder and decoder, therefore no additional data need to be transmitted to the decoder. The experimental results also show that the proposed method improves the coding efficiency of MVC and obtains a better video quality.
