optimization of Time Domain Moving Target Detection Algorithm Based on Improved FT

In order to solve the problems of GMM algorithm in time-domain moving target detection, such as computational complexity, shadows and missed detection, an improved FT algorithm based time-domain moving target detection optimization algorithm is proposed in this paper. The algorithm aims to optimize the speed and accuracy of time-domain moving target detection algorithm by using the idea of combining frequency-domain with time-domain. Firstly, the original FT algorithm is used to perform the preliminary moving target detection, and then the whole moving target detection system is completed by the GMM algorithm. In order to improve the detection rate and ensure better accuracy, this paper improves the original FT algorithm from two aspects of distance measurement and fusion. Experiments show that the proposed algorithm can effectively optimize the detection rate and accuracy of GMM algorithm.
