通过边界集中识别图像形状特性，并返回数值(Images by identifying the boundary shape characteristics of centralized and return values)

this file contain matlab code soure to convert image to text to speach using neuranal network

The above file will give you various kinds of filter that are applied to a single image and so that you will be able see the effect of that filter to the image.

sparse multinomial logistic regression

说明：  不错的matlab书籍，或许能给你点帮助。(good books, perhaps you can help point.)

求卷积,可是做适当的修改，用于MATLAB中。(when we need to carculate convolution.It s indeed useful.)

这是一个改进的查分进化算法，相应的论文为：An improved differential evolution with novel mutation strategy. 发表在IEEE 2014 Symposium on differential evolution (SDE)(This is an improved differential evolution. The corresponding paper is:An improved differential evolution with novel mutation strategy. On IEEE 2014 Symposium on differential evolution (SDE))

找出一个一维数组的周期 例如： 1 2 3 1 2 3 的周期为3 1 2 3 1 2 的周期也为3(Find a cycle such as one-dimensional array: 1 2 3 1 2 3 cycles to 3 1 2 3 1 2 cycles for 3)

用matlab编写的几个图形界面的小程序，开始的几个非常的简单，强烈推介最后一个，本人觉得很有参考价值。(Prepared with a few graphical interface matlab small program, the first few very simple and strongly recommend the last one, I think a good reference.)
