Abstract:

The traditional ViBe algorithm has a “ghost” phenomenon in the detection of moving targets, and it cant detect the complete result for the target with only local motion. Most improved algorithms cant determine the types of defects in overcoming the above defects which reduces the performance of the algorithm. Therefore, for the “ghost” phenomenon, this paper uses edge similarity to make “the ghost judgment”, then combines the three frame difference method to eliminate ghosting. Aiming at local moving target, this paper proposes a new method to determine the existence of local motion, then the whole moving object is obtained by combining the scan line filling algorithm. Experiments show that this algorithm can effectively overcome the defects of “ghost” and local motion, and improve the efficiency and accuracy of the target detection.
