摘要
Abstract
This paper presents a Fourier analysis method for target detection in side-scan image. Using horizon line, vertical line, slope 45° line and slope 135° line spectral mask, the projection of side-scan sonar image in these orientation is obtained. Based on the sum of energy of four orientation projections, a threshold is set to judge target existing, and the position of target is also given. Results show that the method has a perfect performance for regions of interest (target) detection of side-scan sonar image with strong texture.关键词
