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.

我强烈推荐这个应用程序使用MATLAB Wavelet Toolbox。它直观且易于使用，您可以非常快速地启动和运行一般小波变换，特别是离散小波变换。我们一直在我的小组中将它用于 1D 应用程序，但该工具箱中的大部分都是专门为用于 2D 图像处理相关任务而设计的。

作为 Mathworks 特定的 MATLAB Wavelet Toolbox 的替代方案，我还建议使用

我不太确定视频处理，但所有三个都是高质量和免费的。

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)."

您可以试用Matlab Wavelet Toolbox的试用版。

或谷歌dwt matlab。
