Intrduce video motion detection algorithm based on Markov Random Field(MRF). The MRF based motion detection algorithm has more robustness than the others, but it has its defaults yet. Multiresolution is used in the MRF based algorithm .The results show that it can improve the initialization of the algorithm and decrease the mistakes of video motion detection.So,the multiresolution algorithm based on MRF is bat around.Its realization in software is set forth.The multiresolution algorithm based on MRF has wide foreground of application in many fields.
