基本画图程序，原代码，我也是辛苦才收集到的资料，希望能给其他工程师派上用场．-Basic drawing program, the original code, I am also hard to collect the information, hope that they will be useful to other engineers.

通过hough变换求图像中的直线的参数(斜截式)-Through the hough transform for images of straight-line parameters (oblique cut-off type)

可以画出七彩的正六边形并标出定点标号。经调试可以执行。-can paint a hexagon and is marked sentinel labeling. The tests can be implemented.

图型学的一个演示，包括：坐标系的建立，正平行投影，斜等侧投影，斜二侧投影，长方体的建立，旋转轴的建立，长方体绕轴的旋转。-map-a demonstration of the school, including : the establishment of the coordinate system is parallel to the projection, such as lateral oblique projection, the two lateral oblique projection. Cuboid the establishment, the establishment of the axis of rotation, cuboid around the rotation axis.

用VB写的字符识别程序，采用BP神经网络算法，对于脱离Matlab软件进行神经网络算法的编写是一个很好的例子。-Using VB to write the character recognition process, the use of BP neural network algorithm, for from the Matlab software for the preparation of neural network algorithm is a good example.

本源码包含了多种模式识别算法，针对同一次手写的数字，进行各种算法识别，可以比较各种算法的识别效果。-The source code contains a variety of pattern recognition algorithms, for the same handwritten figures, a variety of algorithms to identify, can compare the various algorithms to identify the effect.

一个能够旋转的螺钉，非常好看！-a screw to rotate and extremely good looking!
