Abstract:

In order to solve the problems of low detection integrity and poor detection effectiveness, a moving target detection method for video SAR Based on machine vision is proposed. Firstly, the moving target pixels are matched by Gaussian mixture model to obtain the target region of video SAR moving image. Secondly, the shadow generated by moving target is removed by HSV model and reflectivity algorithm. Finally, the processed target region is input into Yolo algorithm to complete the final video SAR moving target detection. Experimental results show that the proposed algorithm has high detection integrity, high detection rate, low false detection rate and better detection effectiveness.

Key words: Gaussian mixture model, adaptive threshold, HSV model, reflectivity, YOLO algorithm
