Based on fuzzy clustering algorithm , we studied the objective function of the traditional fuzzy c - means algorithm and proposed a modified objective function for fcm ; we discussed clustering validity problem , and a texture segmentation method based on adaptive fcm has been constructed by the guidance of fuzzy clustering validity 在介紹聚類算法的基礎(chǔ)上,研究了模糊c -均值聚類算法目標(biāo)函數(shù)的改進(jìn)問題,提出了基于修正目標(biāo)函數(shù)的fcm算法;討論了聚類有效性問題,在模糊聚類有效性函數(shù)指導(dǎo)下構(gòu)造了一種自適應(yīng)模糊c -均值聚類算法的紋理分割方法。
