通过matlab编写的deVOrNH程序。Mallat变换以及小波变换在边缘提取、图像去噪、数据压缩等中的应用，特别包含了二代提升小波的相关内容，理论与实际相结合。大家想要了解的二进小波、正交镜像滤波器组[qqWxzjW]等概念这里都有体现。-By MATLAB program deVOrNH, Mallat transform and wavelet transform in edge extraction, image denoising, data compression, etc. in the application, especially includes the second generation wavelet related content, theory and practice. We want to understand the two into the wavelet, the quadrature mirror filter bank [qqWxzjW] and other concepts here are reflected.
