Codebook background modeling is to solve the problem of background modeling when the scene includes complex moving objects. For example, the value of the swing in the wind, changes in light, the impact of clouds. A better method is to determine a time series model for each pixel or group of pixels. According to the time series model of each pixel, the value of the pixel position corresponding to the current background is determined. &When constructing the background, observe the value of each pixel in a certain period of time, get the time pixel value curve, and then quantize it into code. It is a compressed form based on the background model of a video sequence;

A multi object tracking method based on PHD filtering and data association is proposed.. The target number and target state estimation of the clutter are eliminated by PHD filtering.. The result of PHD filtering is redefined as the measurement data, and the false alarm and the leakage alarm are eliminated and the target tracks are given.. The simulation results show that the algorithm can effectively improve the tracking accuracy of multi-target tracking and provide the target track information simultaneously..
