大学期间学数字信号处理课程时写的作业放上来也许对大家有用，里面有FIR IIR，和傅立叶变换，FFT等功能。...

fourier变换的原代码,原代码由C语言开发,内包含测试图片-fourier transform the original code, the original code by the C language development, which includes testing Photo

小波分析-wavelet analysis

toolbox_wavelet_meshes专用工具箱-toolbox_wavelet_meshes dedicated Toolbox

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

小波算法以及提升格式的实现。用C++实现,Visual C++,Wavelet-wavelet algorithm and the realization upgrade format. C to achieve, Visual C, Wavelet

该源代码是本人亲自所写，使用DWT对图像可以进行三次小波分解，直接下载可以使用，对图形图像处的同行们非常有用，欢迎下载。-The source code is written by himself, the use of DWT can be three times the image wavelet decomposition, a direct download can be used in the graphic image Department colleagues very useful are welcome to download.

polyphase implementation of biorthogonal wavelet transform

对bmp图像的小波变换，包括其应用，如图像的滤波-bmp image of the wavelet transform, including its applications, such as image filtering

二进小波，非极大值抑制，模极大值的边缘检测程序-Dyadic wavelet, non-maxima suppression, modulus maxima of the edge detection procedure

这个Matlab程序的最主要功能在water.m文件中，当你调用这个函数之后，系统会提示你给哪个图像文件加水印。blockdwt2.m文件，用于在小波频域添加水印logo图片。dmg.m文件产生水印logo图片。watdet3.m文件中的函数实现的功能是检查是否有水印的logo存在。-The main function of Matlab procedures in water.m document, when you call this function, the system will prompt you to add a watermark image files which. blockdwt2.m documents, for the wavelet frequency domain to add a watermark logo image. dmg.m document generated picture watermark logo. watdet3.m realize a function of the document
