用于小波变换的图像信号二维频谱分析

水波纹效果，很神奇的。大家-Water ripple effect, it is amazing.

这是基于人脸检测的一个程序，经过编译后，效果很好，对于做这个方面的同学很有帮助，欢迎大家下载。-This is based on a face detection process, compiled the results very good for students to do very helpful in this regard, welcome you to download.

波形分析,采用FFT运算-waveform analysis using FFT

利用小波的对图像的分解和重构，然后对重构图像消噪，并比较消噪前后的图像。-the use of wavelet image decomposition and reconstruction, and then reconstructed image denoising, and compare the before and after denoising images.

滤波器系数重构运用该算法可以对图象进行去噪处理-reconstruction filter coefficients using this algorithm can be right image denoising

一维及二维小波基细化的程序代码，VC＋＋实现。-One-dimensional and two-dimensional wavelet refinement of the program code, VC to achieve.

FFTW 3.01 目前为止最好的FFT函数库,速度和精度都没得说-far the best FFT functions, speed and accuracy have to say no

一个时频分析的工具箱,主要进行小波变换的信号处理函数-A time-frequency analysis of the toolbox, the main wavelet transform signal processing function

对图像进行二维小波变换，变换后的二维图像将分为四个子带。-The image two-dimensional wavelet transform, the transformed two-dimensional image will be divided into four sub-band.

对一维信号进行小波分解和重构的C程序，绝对误差为10^-11.1）主程序：Mallat.c2）一维信号的输入文件：wdata.dat2）分解重构过程中产生的数据的文件：Data.txt-right one-dimensional signal wavelet decomposition and reconstruction of C procedure, the absolute error of 10 ^-11.1) main program : Mallat.c2) one-dimensional signal input documents : wdata.dat2) decomposition of the reconfiguration process the data in the paper : Data.txt
