The AUV Movement Target Detection Arithmetic Based on LIP Model at Static Background

It is necessary to achieve underwater moving target detection and tracking by sonar image sequences movement target segmentation. The AUV movement target detection arithmetic based on LIP model at static background is proposed. First of all, illumination segments based on human visual characteristics to sonar image, constructs optical flow equation and make the appropriate simplify the discrete processing to saturation region, Weber area, De Vries area of sonar image, at last, completes movement target detection by estimating the optical flow vector by LUCAS-KANADE method. The experiments show that the method can achieve movement target correct extract at static background.
