图形数字识别：

第一步：训练网络。使用训练样本进行训练。（此程序中也可以不训练，因为笔者已经将训练好的网络参数保存起来了，读者使用时可以直接识别）

第二步：识别。

　　首先，打开图像（256色）

　　再次，进行归一化处理。点击“一次性处理”

　　最后，点击“R”或者使用菜单找到相应项来进行识别

识别的结果显示在屏幕上，同时也输出到文件result.txt中-graphics figures recognition : the first step : training network. Use of training samples for training. (These procedures also can not training because I have trained network parameters saved, Readers can direct identification) second step : identification. First, open the Image (256 colors) again, to a treatment. Click on the "one-stop" Finally, Click on the "R" or use the menu item corresponding to find the identification of the identification results on the screen, also output to a file which result.txt
