Moving Object Detecting Method in Video

A method of moving object detection that integrates image gradient information with motion information is described herein. One multi-scale morphological gradient operator is used to detect gradient information. This operator has a very good effect on the detail of the edge location. The result is superior to the traditional method in edge continuity and isotropy. Past approaches have used methods of detection based on motion information and edge information, but this is the first to use a multi-scale morphological gradient operator. The implementation described can operate on lower resolution images under difficult conditions. Novel contributions include: 1. Based on multi-scale morphological gradient operator, this algorithm is robust to noise, object shadow, and illumination. 2. Using interframe difference and only the first two frames, this detection method uses very little computation and is suitable for real-time applications. 3. This method can detect rigid-body or non-rigid-body moving objects among video sequences with complicated backgrounds.
