| Abstract: | The mearsurement of optical flow is the fundamental issue of image sequence processing and video mining. In this paper,the principle of optical flow method is introduced first. Four main catalogues of optical flow algorithms,including the differential technique,region-based matching, energy-based method and phase-based method,are disscussed in detail,especially the commonly used energy-based method. The evaluation methods and collection of optical flow methods are also introduced in this paper. |
