The invention provides an image segmentation processing method based on bat optimal fuzzy clustering. The bat?algorithm, which is an evolutionary?algorithm good in performances, can well solve the shortcomings that a traditional FCM clustering segmentation method relies too much on an?initial clustering?center and can improve to a large degree the possibility of converging the global optimal solution. The bat?algorithm can directly adopt a decimal system for coding, and compared with most evolutionary?algorithms which adopt binary systems for coding, the calculation process?is more convenient, and the clustering segmentation efficiency can be improved to a large degree.
