一种基于直方图匹配的立体视频颜色校正算法

针对立体视频序列视点间颜色不一致的问题,实现基于直方图匹配的立体视频颜色校正算法。深入分析视点图像间颜色存在的乘性和加性差异,结合颜色差异建模,使用直方图匹配算法校正颜色误差。实验结果表明,本文实现的颜色校正算法计算复杂度较低,并且在保持图像视觉效果的同时,能较好的消除参考图像与目标图像之间的颜色差异,是一种有效的立体视频图像颜色校正算法。

A Color Correction Algorithm for Stereo Video Coding Based on Histogram Matching

In order to solve non-consistence of color appearance in stereoscopic video, a stereoscopic video color correction algorithm based on histogram matching was realized. Through analysis of stereoscopic images color existing in multiplicative and additive differences, using histogram matching algorithm to achieve color correction combined with the color difference modeling. The experimental result showed that the realized color correction algorithm could not only have lower computational complexity, but also correct the stereoscopic video color to be consistent.
