视差图误差检测与校正的通用快速算法

为了获取精确的立体匹配结果 ,提出了一种通用的视差图误差检测与校正算法。算法首先定义一个新的全局顺序匹配约束 ;然后将其用于视差图后处理过程 (而不是视差计算过程 )中 ,以检测出视差图中的匹配交叉区域 ;最后提出一种零交叉校正方法 ,校正其中的误匹配点。通过对一组真实立体图像序列及其视差图的实验 ,进一步证明了该算法的有效性。该算法可以作为视差图后处理过程附加在各种立体匹配算法之后

General and fast algorithm for disparity error detection and correction

General error detection and correction algorithm for disparity maps is developed to provide precise stereo matching results. A novel global order matching constraint was applied to post process the disparity map (but not in the disparity computation process) to detect cross regions in the disparity map. A zero cross correction algorithm was proposed to correct the erroneously matched positions. The algorithm was tested with a set of real stereo images and their corresponding disparity maps. The quality of the corrected disparity map was greatly improved. The method can be appended to various stereo matching algorithms as a general technique for post processing of disparity maps.
