基于PCA降维的k-means算法，附带有检测正确率的源码以及相应的检测数据(PCA dimensionality reduction based on k-means algorithm, source code comes with the correct detection rate and the corresponding test data)

此程序主要是通过使用小波达到图像文件压缩的目的，可以比较不同的小波函数和压缩次解压缩后图像文件的差异，注意图像是二维的处理时使用二维的小波函数(This process is mainly through the use of wavelet compression to achieve the purpose of image files, you can compare different wavelet functions and extract the compressed time difference after the image file, pay attention to the handling of two-dimensional image is the use of two-dimensional wavelet function)
