MOTION DETECTION METHOD FOR DETECTING MOTION OBJECTS IN VIDEO FRAMES GENERATED FROM A VIDEO SURVEILLANCE SYSTEM

摘要

A motion detection method for detecting motion objects in video frames generated from a video surveillance system. The motion detection method includes the steps of (1) calculating and accumulating a number of a current macro block row by row, the current macro block having a motion vector, which has a predetermined characteristic and a predetermined relation with a motion vector corresponding to a macro block preceding the current macro block, and a current macro block row where the current macro block stays having a position relation with a macro block row preceding the current macro block of the video frame which the motion objects occupy, and (2) determining the motion objects occupy the video frame when the number is larger than a predetermined value.
