说明：  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。
(Has been preserved trained network weights, so the identification procedures used for the first time, you can directly run the \ Release directory of the executable file, and then on the picture of the test directory to read into the picture, identification. Of course, readers can also use the training samples of the training network, but to pay special attention to training samples, otherwise it may cause very low recognition rate. Training sample selection principle is that, as far as possible have representation in the training time not too long, the number of training samples as many as possible.)
