中文说明：在图像处理中需把连续小波及小波变换离散化才有意义．作为一种方便的形式，计算机实现中往往对小波进行二进制离散，并把经这种离散化后的小波及相应的小波变换称之为离散小波变换。将传统的图像匹配技术和小波滤波技术相结合，利用小波的平移不变性，提出了一种改进的图像匹配算法，并给出了仿真实验，收到了良好的效果
English Description：
Image processing in the discretized continuous Wavelet transform can be meaningful. As a convenient form of computer implementations tend to binary Wavelet discrete and the discrete Wavelet called Discrete Wavelet transform and the wavelet transform. Combining traditional image matching with Wavelet filtering techniques, translation invariance Wavelet, proposed an improved image matching algorithm and simulation experiments, received good results
