| Abstract: | Ship waterline is at the junction of water and shipboard regions, and precise positioning of ship waterline affects the accuracy of ship load calculation directly. For the characteristics of ship waterline image, features of BWS and DD are extracted based on texture spectrum method,then ship sub-images are classified by K-means clustering algorithm in order to segment ship waterline images. As a result, the location of waterline is determined quickly and accurately. Experimental results show that proposed algorithm has high speed and accuracy during precise positioning of ship waterline. |
