Abstract: Use the center of the Kernel Fuzzy C-Mean(KFCM) as the center of the new method,and use a difference control function to modify the membership of the spatial information FCM(SFCM).The new membership gives different measurements to the edge areas,smaller areas,noise with the inside areas.The results show that the proposed algorithm can provide a more better result than FCM algorithm and SFCM algorithm,and the proposed method has much fewer iterations.
摘要: 应用模糊核聚类产生的聚类中心作为FCM方法的初始聚类中心,同时引入差异控制函数对考虑了空间信息的FCM方法的隶属函数进行修正,加入差异控制函数的隶属函数将边缘区域、面积较小区域、噪声与区域内部点区别对待,提高了分割的正确性。实验结果表明:对加入噪声的MR图像应用该文方法分割,得到的结果相对于标准FCM方法以及加入空间信息的FCM方法具有更好的正确性和分割结果的完整性,同时算法的迭代次数也极大减少了。
