基于遮挡修补的TV-L1光流算法
TV-L1 optical flow algorithm based on block repair
摘要
Abstract
The TV-L1 optical flow algorithm is relatively popular currently, can reduce the amount of computation with taking advantage of the bidirectional solving mechanism, without losing the accuracy, but cannot effectively process error optical flow component defects caused by interruption, occlusion and other errors. This paper firstly judges optical flow component of occlusion area based on motion coherence of forward and backward optical flow, handles occlusion area by means of Monotone decreasing function, suppresses error light flow of the occlusion area spread to the neighborhood, and presents lateral repairing of the same frame neighborhood optical flow and the longitudinal repairing of the adjacent frames light flow. Experiments show that this method can process occlusion very well, and enhance the calculation precision of optical flow.关键词
