摘要 介绍了一种求解光流方程的新型数值方法。针对变分光流法无法有效检测由于间断、遮挡等造成的错误光流分量的缺陷,引入了光流有效性检测技术,同时提出了邻域修正法来修正错误分量。并采用结构纹理分解、加权中值滤波、金字塔等高效的光流技术,进一步增强了光流算法的精确性与实用性。 A new type of numerical method to solve variational optical flow equations is illus- trated. Introduce an efficient flow vector availability strategy to detect the wrong compo- nents which are caused by discontinuities, occlusions, etc, and then, a neighboring correc tion approach is proposed the correct them. Some advanced techniques are employed into the compute procedure, which further strengthen the accuracy and applicability of the variational optical flow algorithms.
