这段程序的主要功能是完成图像的归一化处理。(The primary function of this process is to complete the image of normalized.)

this file is used to enhance the image using histgram eqaution

A source code to convert cartesian coordinates to Log-Polar coordinates for an image.

对原始语音进行上采样和下采样，分析对比他们的时域图和频谱图。最后对比原始语音、75HZ激励、150HZ激励以及噪声激励下的效果(SOME SIMPLE MANIPULATIONS OF SOUND USING DIGITAL SIGNAL PROCESSING The original sound and its spectrogram Downsampling the waveform downsampling Upsampling the waveform Linear filtering the waveform Original speech The source-filter model of speech Speech with 75-Hz excitation Speech with 150-Hz excitation Speech with noise excitation)

实现二维正向正态云发生器 ，非常好用 (2D forward the normal cloud generator)
