一位网友编写的图像处理特效的程序，可以实现图像处理的大部分功能.不过要是想处理好当然用ps-prepared by the effects of image processing procedures can be achieved most of the image processing functions. But if they wish to handle the course with ps

本目录主要包括：文档和两个源代码。 其中一个源代码是识别程序的，另一个是一个矩阵类库的，书里面也使用过，所以一并附上。 因为已经保存了训练好的网络权值，所以第一次使用识别程序时，可以直接运行Release目录下的可执行文件，然后对图片目录中的测试图片进行读入、识别。 当然读者也可以自行用训练样本训练网络，不过要特别注意训练样本的选择，否则可能造成识别率很低。训练样本选择的原则是，尽可能的有代表性，在训练时间不至于太长的情况下，训练样本数目尽量多。-Catalog include: documentation and two source code. One of the source code is the identification procedures, and the other is a matrix class library, the book which is also used, so be accompanied. As it has saved the trained network weights, so the first time the use of identification procedures, he can run Release directory of the executable file, and then the picture directory to read the test pictures to identify. Of course, the reader can also be its own training network with training samples, but pay special attention to the training samples, otherwise it may result in the recognition rate is very low. Training sample selection principle is that as much as possible representative, in the long training time Buzhi Yu circumstan
