- Abstract:
-
Stochastic selection of a clustering center would cause the iterative process to become trapped in a local extremum. To overcome this image segmentation problem, a hybrid method was proposed. It combined an ant colony algorithm with dynamic fuzzy clustering analysis. Thus the superior ability of the ant colony algorithm became available for dealing with local extrema. The resulting algorithm dynamically determined the number of clusters as well as clustering centers. Within the optimization procedure, we introduced a crowd degree function to improve the convergence rate. In addition, the parallelism and positive feedback effect of ant colony algorithm were employed to increase clustering precision. The proposed algorithm was used in the segmentation of medical images. A series of comparative experiments showed that the algorithm has improved ability to detect fuzzy or thin edges.
