指纹识别算法的平滑处理和加强处理（高通滤波）有sobel prewitt log方法。保留的为prewitt。另一个文件是图像的二值化处理和去噪。后面的程序还在制作中-Fingerprint recognition algorithm to smooth and enhance the process (high-pass filter) has sobel prewitt log method. Reserved for the prewitt

实现高通滤波器的程序代码，很方便，很实用-High-pass filter code, very convenient, very practical
