Abstract: An optimization method is proposed for moving object detection in image sequence. As to the existence of “pseudo object” noise when the different method for indoor object detection is applied and “vestigial-image” noise problem while background estimation method for outdoor object detection is used on for short sequences, this paper finds and employs the relativity between twice difference to detect and eliminate the “pseudo object”, and then combines difference and background estimation method to eliminate the “vestigial-image” noise that cannot be avoided when only the latter is used. Experiment results show that, the proposed method can not only eliminate the “pseudo object” and “vestigial-image” noise, but also help to improve detection integrity remarkably.
