摘要
A method and system for real time converting a dynamic video to a set of static image frames includes segmenting the video into a plurality of frames. Significant parts of the frames are selected to comprise interest points. An operator estimates a motion trajectory of the interest points for real time computing of a global motion. Upon detection of global motion, selected key frames are selected from the set of static frames to represent the dynamic video. Interest points are identified as areas of high gradient and are further minimized by limiting interest points by imposing a grid on image frame and limiting the interest points to one point per grid cell.
