离散小波变换
I need help for discrete wavelet transformation source code with MATLAB.
Could I know full discrete wavelet transformation source code with MATLAB that can be used for video processing?
Especially I need code for a Wyner-Ziv filter using wavelet transformation with MATLAB.

作为 Mathworks 特定 MATLAB Wavelet Toolbox 的替代方案，我还建议使用
我不太确定视频处理，但这三个都很好 -优质且免费。
As an alternative to the Mathworks-specific MATLAB Wavelet Toolbox, I would also suggest the
I am not too sure about video processing, but all three are good-quality and free.
对于此应用程序，我强烈推荐 MATLAB Wavelet Toolbox。 它直观且易于使用，您可以快速上手并运行一般的小波变换，特别是离散小波变换。 我们一直在我的团队中将其用于 1D 应用程序，但该工具箱的大部分内容是专门为用于 2D 图像处理相关任务而设计的。
I would strongly recommend the MATLAB Wavelet Toolbox for this application. It is intuitive and easy to use and you can get up and running very quickly on wavelet transforms in general, and the discrete wavelet transform in particular. We have been using it in my group for 1D applications, but much of the toolbox is designed specifically to be used for 2D image processing related tasks.
您可以尝试 Matlab Wavelet Toolbox 的试用版。
或者谷歌 dwt matlab。
You could try a trial version of the Matlab Wavelet Toolbox.
Or google dwt matlab.
我可以推荐这本书“数学中的涟漪：离散小波
变换”作者：A. Jensen 和 Anders la Cour-Harbo（ISBN：
3-540-41662-5）。 事实上，几年前，我参加了一个
由其中一位作者举办的课程。 本书包含MATLAB
源代码和第 13 章，从第 211 页开始，是“Wavelets in
MATLAB”。
它还有 2D 变换示例（针对图像）。第 6 章，
“二维变换”，以“在本章中
我们将简要展示离散小波变换如何
应用于二维信号，例如图像”。
对于某些示例，它使用免费的 Uvi_Wave 小波
工具箱 - “...是一套基于小波处理的
在... MATLAB ... 下实现的函数包括
一维或多维的小波变换函数...
包括小波包变换（一和二
维）”。
I can recommend the book "Ripples in Mathematics: The Discrete Wavelet
Transform" by A. Jensen and Anders la Cour-Harbo (ISBN:
3-540-41662-5). In fact, a few years ago, I participated in a
course held by one of the authors. The book contains MATLAB
source and chapter 13, starting on page 211, is "Wavelets in
MATLAB".
It also has 2D transform examples (for images). Chapter 6,
"Two Dimensional Transforms", starts with "In this chapter
we will briefly show how the discrete wavelet transform can
applied to two dimensional signals, such as images".
For some examples it uses the free Uvi_Wave Wavelet
Toolbox - "... is a set of Wavelet Processing based
functions implemented under ... MATLAB ... includes
Wavelet Transform functions for one or more dimensions...
includes Wavelet Packet Transform (one and two
dimensional)."
