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.)

说明：  用matlab实现简单的车牌自动定位程序,内含两个子函数(Matlab license plate with a simple automatic positioning process that includes two Functions)

说明：  一种基于角点信息和透视变换的图像镶嵌源代码(A corner-based information and perspective transformation of the image mosaic source code)

说明：  在实验中，处理记录数据文件是经常要做的，而用Matlab来处理是我最推崇的，方便快捷，数据文件格式任意设置，均可处理，将数据文本data.txt,用Matlab来处理，用这个小程序做来非常容易，而且处理后得到的图形可直接Copy到各种需要的文件中。(In the experiment, record data processing documents often do, using Matlab to be dealt with me most respected, convenient and arbitrary data file format settings can be handled data.txt text data using Matlab to deal with the use of such small programs very easy to do, but after the Copy graphics directly to the needs of the document.)
