手写数字识别，很不错的啊！具有图形用户界面，使用方便…

画美国国旗，和中国国旗，都是标准尺寸。还可以画直线，并且可以把直线用拖拉鼠标的方法放大-painting the American flag and the Chinese national flag, is a standard size. Can also painted straight lines, and can be used straight-line method tractor Mouse Click

一个日文手写识别源码，有较高的参考价值。-a Japanese handwriting recognition source, a high reference value.

基于BP神经网络对印刷体字符图象进行识别,经过前期处理,获得64*64的二值图象,其二值图象数据作为神经网络的输入.-BP neural network based on the characters of the print images to identify, after pre-treatment, access to 64* 64 binary image, and the second value of image data as the neural network input.

实现基于8bit的BMP切片的三维重建，解压后，用CMake配置即可。-8bit of BMP-based three-dimensional reconstruction of the slices, after extracting, you can configure with CMake.
