High resolution sonar image segmentation is the foundation of the sonar vision auto target recognition. This paper manages to use the clustering method realizing image segmentation.Particle Swarm Optimization algorithm is a kind of optimization technology based on aptitude searching and with high effect of global optimization, and by incorporating the local search of Fuzzy Clustering Method(FCM) and taking the clustering result of PSO as the initialized value of the FCM.Use fuzzy measures and fuzzy integral...
