针对FCM算法的运行时间长和计算量大的问题，提出了改进的FCM算法，先将图像分割成窗口大小的子块，然后以子块为单位提取特征向量，用FCM聚类粗分割，然后对边缘子块，以像素为单位从新提取特征向量，进行细分割。分割后的结果提高了运行速度和分割精度。-For the FCM algorithm and the calculation of long run the problem of large proposed improved FCM algorithm, first image into bl

iii) Discrete Cosine Transform The transform of a signal is just another form of representing the signal. It does not change the information content present in the signal. Discrete cosine transform is widely used in image and video compression appl

the segmentation is a process which like to segment the data at each partition of block .in this we have colour image by which is segment the data
