Systems and methods for color compensation in multi-view video

摘要

An apparatus and a method for color compensation in multi-view video is provided. Video sequences corresponding to a common scene of interest are captured and processed using the master and slave channels respectively. A compensation gain is calculated based on a set of global color ratio statistics obtained from the master and slave channels. The compensation gain is applied to the slave channel. An initial master color correction matrix is combined with a master color matching matrix to obtain a final master color correction matrix. The initial slave color correction matrix is combined with a slave color matching matrix to obtain a final slave color correction matrix. The master and gain-compensated slave channels are color-compensated by applying the final master and final slave color correction matrices to the master and gain-compensated slave channels, respectively.

1. A method for color compensation in multi-view video comprising:
sensing a first video sequence in a master channel; sensing a second video sequence in a slave channel; wherein the first and second video sequences are acquired from a common scene of interest; generating a set of global color ratio statistics from the master channel and the slave channel, wherein the global color ratio statistics are based on a ratio of master channel image data to master channel image size and a ratio of slave channel image data to slave channel image size, and wherein the slave channel image size depends on the similarity between a master channel image and a slave channel image; calculating at least one compensation gain based upon the set of global color ratio statistics; and applying the at least one compensation gain to the slave channel to obtain a gain-compensated first slave channel.
