Fuzzy c-means thresholding用于图像分割，有示例图，可以运行-FCMTHRESH Thresholding by 3-class fuzzy c-means clustering



　[bw,level]=fcmthresh(IM,sw) outputs the binary image bw and threshold level of image IM using a 3-class fuzzy c-means clustering. It often works better than Otsu s methold which outputs larger or smaller threshold on fluorescence images.
