Research on improved meanshift algorithm based on fuzzy control principle

Machine vision is now widely used. The traditional Meanshift algorithm can easily cause the target to be lost due to its fixed core radius, which makes the target change in size and direction, thus affecting the whole tracking result. Aiming at these problems, this paper introduces the fuzzy control method, based on the adaptive fuzzy mechanism of the similarity function value to select the appropriate dynamic kernel radius in real time, thus improving the tracking effect. Through the comparison of the tracking accuracy before and after the improvement of the video stream of the basketball game, the average accuracy of the improved tracking can reach 73.76%, which is 9.28%, so the target tracking of the athletes on the sports field can be effectively realized.
