中文说明：matlab实现9/7双正交小波变换，将图像分解到频域-matlab realize 9/7 biorthogonal wavelet transform, the image is decomposed into the frequency domain。旨在加强双正交小波的去噪功能
English Description：
MATLAB implementation of nine-sevenths bi-orthogonal Wavelet transform, breaks up an image into the-MATLAB realize 9/7 biorthogonal Wavelet transform in the frequency domain, and the image is decomposed into the frequency domain. Aimed at strengthening the bi-orthogonal Wavelet denoising function
