- GPU上的小波变换程序代码,学习的经典例子,个人实验代码。
rebuildresposebyridgeofwavelet
- 小波变换模极大值重建信号的源程序。这是用小波变换模极大值重建信号的源程序,数据是一心电信号,在matlab6。5下实现,来源于胡广书的《现代信号处理教程》附属光盘,现提供给大家供大家学习参考,滤波部分可以根据个人情况进行修改。程序包含四个部份,其中wave_peak实现信号的分解并求出模极大值

Wavelet
- 小波变换的工程分析与应用,杨福生的著作,我个人认为比较好的一本书-Wavelet transform and application of engineering analysis, Yang Fusheng book, I personally think that a good book
wodeshuiyinzhuchengxv
- 这是个人在工作中的一个小的matlab源码。包含了水印过程中一些常用的步骤,从置乱技术、水印的嵌入、水印性能测试。对于做水印初入门的人有一定的借鉴意义-This is the work of individuals in a small matlab source code. Contains the watermarking process, some common steps, from the scrambling technology, watermark embedding, wate
lift97mlhard
- 个人编写的提升格式97小波去噪,采用硬阈值法,三层分解,包括小波变换,去噪,逆变换三步-Written format of 97 individuals to enhance the wavelet denoising using hard threshold method, three decomposition, including wavelet transforms, denoising, inverse transform three-step
aboutwavelet
- 个人收集的关于小波的多个实例程序,包括提升小波、mallat算法等等,实例程序较多,便于大家学习参考-Personal information collected on multiple instances of wavelet procedures, including lifting wavelet, mallat algorithm, etc., examples of procedures more convenient reference for them to learn
DCT
- 这段程序是,J(p,q)代表的二值水印图像,二值水印图像的像素值只有0和1,所以if J(p,q)==0,a=-1 ,是如果水印图像像素值是0的话,让a=-1,当水印像素值为1的话,让a=1,我个人认为是为了提取时候好提取-DCT digital watermark embedding and extraction of
FWT
- 根据个人对小波的理解,用卷积进行小波分解的一个简单小程序,有助于理解。-Based on personal understanding of Wavelet , I write a simple little program by myself that use convolution to do a wavelet decomposition,it can help to understand.
