image noise reduction by level dependent thresholding

it is a function of wavelet transform

小波变换学习的绝好资料,,不同于一般的数学抽象推导,一定要看看.我看了以后收获非常大-Exellent material for wavelet study. It is different from general mathematical calculations. You should read it. I benefit a lot from reading it.

白光的单缝衍射-white single-slit diffraction

这个是一个二维小波变换的计算程序，里面包括四个程序包，可实现不同的功能-This is a two-dimensional wavelet transform of the calculation program, which includes four packages, different functions can be realized

本程序用于实现一层小波变换，即在频域对图像进行处理-the procedures used to achieve a layer of wavelet transform, in the frequency domain for image processing

本算法结合小波变换和SVD奇异值变换，实现了水印的嵌入和提取，载体图像的鲁棒性和水印的不可见性，提取出的水印图像的和原水印图像基本一致，抗攻击性强。-The algorithm combines wavelet transform and SVD singular value transformation, achieved watermark embedding and extraction, vector image watermark robustness and invisibility, the extracted watermark image and the original watermark image are basically the same, anti-attack and strong.

小波变换的一些源程序-wavelet transform some source

有关小波变换的Matlab程序，内容较为详实而且易懂，可以在其基础上编写自己的应用程序-the wavelet transform Matlab procedures, as more informative and easy to understand, in its own on the basis of the application procedures

图像压缩中的小波变化-Image Compression Wavelet changes

用matlab实现的基于小波变换的图像增强去噪-achieved using Matlab based on wavelet transform image enhancement and denoising
