In this study, clustering of black BADUK stones` image were performed to recognize the individual stone from its closely spaced and partially occluded image. And the clustering perfomance was compared between the classical methods and fuzzy C-means method. As a result, 2 BADUK stones` image was segmented precisely in every methods, but more than 3 stones the segmentation was depended on its shape. Fuzzy C-means method could be segmented correctly to 4 stones regardless of its shape, and it could be applied to the unknown number of clusters.
