Moving target detection based on improved three frame difference and visual background extractor

In view of the ghost phenomenon appear in the ViBe (Visual Background Extractor) algorithm, by analyzing the common motion detection algorithm, this paper presents an improved algorithm based on ViBe. The method uses real-time characteristic method of frame difference, combines the three frames difference images and ViBe difference image to logical operation, it can make up the frame difference method of moving objects which always appears empty phenomenon, and quickly eliminate the first frame ViBe background modeling appears “ghost” phenomenon. The experimental results show that the improved ViBe algorithm can quickly eliminate the “ghost” phenomenon, and has good robustness.
