MOTION VECTOR BASED COMPARISON OF MOVING OBJECTS

摘要

The present invention proposes to analyze movements of objects in video sequences (e.g. sport videos) by performing motion estimation to determine motion vectors at each frame. With the calculated motion vectors the movements of the object(s) (e.g. athlete(s)) can be quantitatively measured. Based on this movements in two videos can be compared at each individual frame of the video sequence. Different approaches (e.g. color coding) can be used to visualize and compare the movements. With motion estimation intermediate frames can also be inserted to enable better movement comparison in two given videos.
