Abstract: This paper proposes an algorithm of moving point target detection from Gauss stationary random field. It trains the images from the stationary random field and acquires the probability mean and variance by MLE , then does probability threshold process to every frame according to 3-σ principle and accumulates the difference of multiple frames. According to the depth of the Bi-direction chain in the sum frame, it does track detection. The experimental results show that the method is effective.
