⛄ 内容介绍

Particle Swarm Optimization (PSO) is population based stochastic algorithm to form clusters with the help of fitness functions. PSO clustering algorithm is widely used in pattern recognition methods such as image segmentation where PSO defines less number of clusters compared to conventional clustering approaches. Level Sets image segmentation aided with the clustering gives fast convergence towards the desired boundaries of the object to be segmented. Here in this paper a novel approach of image segmentation using PSO clustering applied to Level sets is been presented where PSO performs better than KFCM by generating more compact clusters and larger inter cluster separation. The proposed method is successfully implemented on the images and results obtained show the effectiveness of the approach.
