这是关于matlab数字图像处理来针对图像处理和检索的论文,从整体上来把握框架和过程。(This is the digital image processing for matlab image processing and retri of paper, the whole to grasp the framework and process.)

How to transmit a QPSK signal

在对比度小的灰度图像中加入噪声，再对图像进行滤波和直方图均衡化，对图像进行增强，并比较了不同参数时的增强效果(In contrast, the gray image by adding a small noise, then the image filtering and histogram equalization of image enhancement, and compared the effect of different parameters of the enhanced)

Matlab中的fsolve函数源代码。可用于解方程。(Matlab fsolve function of the source code )

用最大距离法对K均值的初始聚类中心进行确定(max distance algorithm)

此程序主要是通过使用小波达到音频压缩的目的，可以比较不同的小波函数和压缩次数音频文件的差异(This process is mainly achieved through the use of wavelet purpose audio compression, you can compare different compression of the wavelet function and the difference in the number of audio files)

It is a single phase half controlled inverter.
