主要用于图像经小波变换压缩图像，并计算压缩后的图像压缩性能即压缩比和信噪比(Mainly used for image compression by wavelet transform image, and calculate the compressed image compression performance that the compression ratio and signal to noise ratio)

说明：  快速傅里叶变换，fft，ourrafft master(Fast Fourier Transform Algorithm)

vc实现虚拟示波器，没有测试过不知道能用吧(vc virtual oscilloscope not tested do not know can)

短时傅里叶变换 快速傅里叶变换对音频信号处理 频谱分析 (fast fft )

用于产生各种多小波滤波器系数的程序，包括Cl2小波，GHM多小波等等，很好用(Used to produce a variety of multi-wavelet filter coefficients procedures, including Cl2 wavelet, GHM multiwavelet and so on, very good use)

利用小波变换进行改进阈值信号去噪 (Improvement threshold signal denoising using wavelet transform)

说明：  借助小波变换在时频分析上的优点，提取地面运动目标的回波信号特征在目标识别中加以运用(With wavelet transform in time-frequency analysis of the advantages of extracting ground moving target echo signal characteristics to be used in target recognition)

自己编写离散小波变换与离散小波反变换程序对一幅图像做2级小波分解（离散小波变换）与合成（离散小波反变换）(Write your own discrete wavelet transform and discrete wavelet inverse transform procedure on an image to do two wavelet transform (DWT) and synthesis (discrete wavelet inverse transform))

美国Rice大学提供的matlab 小波代码，要比matlab自带的matlab更易用(Rice University, USA matlab wavelet code comes than easier to use)

小波变换在图像处理中应用于图像分析，图像压缩，图像去噪等。本文就小波变换理论和matlab语言的小波分析工具箱做了简单阐述。(Wavelet transform in image processing applied to image analysis, image compression, image denoising, etc.. In this paper, wavelet transform theory and wavelet analysis matlab language to do the simple toolbox on.)
