| Abstract: | The recognition and position of the seabed target is the base of salvage in sea. After analyzing the image of the high resolution side-scan sonar,a method that is used to extract and position,it uses more methods of image processing sequentially,such as binating,median filtering,opening and closing,and extracting of canny operator,by use of the relation of target and shadow in the sonar images. Experiment results show that this method is available and effective. |
