Abstract:

In a real scene, due to different illuminant color, corresponding points that are projections of the same scene point may have different RGB values of pixels and performance of stereo matching algorithms can be degraded. In order to improve the performance of algorithms, RGB proportional space is proposed based on the color formation model and pixel values are transformed into this space. We present an adapt support-weight algorithm based on RGB proportional space. Experimental results show that compared with the algorithm in the traditional RGB vector space, our algorithm can obtain better disparity maps.
