Using vqlbg to implement the vq algorithm

说明：  对被噪声污染的灰度图像进行滤波，是一种自适应滤波器。(denoiseing for the gray scale image)

对采样率进行变换，通过插入零，然后再做低通滤波，实现采样率的提高(Change the sampling rate by inserting zeros, and then do a low pass filter, the sampling rate to achieve the improvement of)

VEHICLE SPEED AND SPACING CONTROL VIA COORDINATED THROTTLE AND BRAKE ACTUATION

说明：  对C一个详细的讲解里面有很多例子 可以多学习学习(a good programming book)

这是MATLAB图像处理函数的具体讲解，非常实用具体，对图像研究方面的编程很有帮助(This is the MATLAB image processing function on the specific, very concrete and practical, research on the image programming helpful)

短时傅里叶变换可以用差分模式来实现，对书上的运算式做了稍许的改变。改变-计算差分序列的第一列数据时用的是第一列的元素减去当前行的最后一列元素。原算法中采用的是第一列元素减去下一行第二列元素。原算法加窗之后结果比较好，不加窗时结果误差很大，而改变之后的算法不加窗效果依然很好。(Short time Fourier transform can be used to achieve the differential mode of expression on the book made a slight change. Change- calculating the difference sequence of the data with the first column is the first column of the matrix by subtracting the current element in the last column of row. Is used in the original algorithm subtracts the elements of the first column of the next row and the second column elements. After the results of the original algorithm windowed better, when the results window without great error, and after changing algorithms no window effect is still very good.)
