说明：  们讨论图像的重构。我编写的重构程序中，为了比较分解图像和重构图像，首先绘出经过小波分解的图像，然后再进行重构。在绘制分解图像和重构图像的过程中，要注意数据格式的转换。(Image Reconstruction discussed. I prepared reconfiguration process, in order to compare decomposition of images and reconstruction of images, first of all draw after a wavelet decomposition of the image, and then reconstructed. Decomposition in the rendering image and reconstructed image of the process, attention should be paid to data format conversion.)

模糊聚类的改进--先用减法聚类得到初始点，而后用模糊聚类得到聚类中心，能够提高聚类的速度和精度(Improved Fuzzy Clustering- first get the initial point subtraction clustering, and then get the cluster center with fuzzy clustering, clustering can improve the speed and accuracy)
