Wireless sensor network mac protocols.Its explanations...and implementations

mri_toolbox是一个工具用来MRI. 来自于SourceForge, 我上传这个软件,希望能结识对医疗软件感兴趣的兄弟.(mri_toolbox is toolbox for mri.This is from the sourceforge I want to share this those who are interested in medical software.)

此程序可以实现批量将彩色图像转换为灰度图像，只需添加图像位置即可。(This program can batch convert color images to grayscale images, simply add the image location.)

白噪声及有色噪声序列的产生，有色噪声序列可以看成由白噪声序列驱动的线性环节的输出(White noise and colored noise sequence generated colored noise sequence can be seen as the output of the linear part of the sequence driven by white noise)

This function is for training a codebook for vector quantization. The data set is split to two clusters, first, and the mean of each cluster is found (centroids). The disttance of each vector from these centroids is found and each vector is associated with a cluster. The mean of vectors of each cluster replaces the centroid first. If the total distance is not improved substantially, The centroids are each split to two. This goes on untill the required number of clusters is reached and the improvement is not substantial.

详细说明了python及matlab的特点，及其各自特点，并将其联合，进行编程。(A detailed description of the characteristics of python and matlab, and their respective characteristics, and their joint, for programming.)

共7个matlab程序及两幅原始待处理图像，功能是图像压缩的实验，分别运用了DCT（1个程序），小波变换（5个程序）和小波包变换（1个）对图像进行压缩，各个程序的作用及程序注释已在程序中做了详细说明,程序均可直接运行(matlab program for image compression ,using DCT wave,wavelet,wavelet packet methods respectively .)

fft calculation of any input signal

this code written for solve a sample test function by pso based on mutation.

vit程序清晰简单，容易阅读，matlab调用易实现(vit procedures clear and straightforward, easy to read, matlab call easy to realize)
