Calculate the NPCR between images

这些是利用matlab仿真通信系统中的调制的一些小程序，希望有用(These are the use of matlab simulation of communication systems in the modulation of a number of small procedures in the hope useful)

计算一副图像的信息熵，如需计算多幅图像，只需修改名称即可(Calculating an image information entropy, calculated for multiple images, you can just change the name)

说明：  在聚类分析中,模糊c-均值算法是应用最广泛的聚类算法之一,针对该算法对初始化敏感,容易陷入局部极小点的缺点,论文提出了一种基于核的模糊聚类算法.在算法中将核方法与模糊可能性算法相结合,将模糊c-均值算法结果作为初始中心,放松了对隶属度归一化的条件,对噪声有更好的处理能力.IRIS数据和人造数据的实验结果表明该算法的有效性(Chun-Fu Lin,Sheng-De Wang.Fuzzy support vector machines.[J].IEEE transactions on neural networks / a publication of the IEEE Neural Networks Council,2002,13(2).464-71.)
