VB图像识别，关于人脸识别方面的，还有许多需要改进的地方

包含完整的大津法二值化算法，计算图像的二阶距-Act contains a complete Otsu binarization algorithm to calculate the image of the second-order distance

资源描述本程序涉及交通标志识别，程序特色： 1、界面友好，操作简单 2、能对任意多种类别的交通标志进行识别 3、程序执行效率较好 程序使用说明： 1、在程序主界面中手动“添加类别”：禁止鸣笛、人行通道、T型岔道。 2、从下拉框中选中某一类别后，点击左下角“添加训练图像”按钮：输入3种模式的训练影像路径。 3、点击“图像预处理”按钮：从右窗口可以直观看出预处理后的能被正常识别的标志区域（红框表示）。 4、剔除无效数据，即未能识别的数据。通过右窗口查看预处理结果，将未能正确识别的图像删除。并重新进行图像预处理。 5、预处理完后，点击左上角菜单栏的“训练”按钮，训练数据集会输入神经网络并通过反向传播方式更新权值。 6、训练好网络后，点击“校验”选项，在弹出的校验对话框中，分别输入各类别的校验图像路径，程序将利用校验集对网络性能进行验证。通过设置不同的隐藏神经元数，最小二乘和Kullback -Leibler 距离指标值也不一样。重复改变隐藏神经元数的设置，比较检验结果，选取距离指标最小值对应隐含神经元数作为最优训练结果。 7、神经网络确定后，点击菜单项“测试”按钮。在弹出的测试对话框中输入测试图像路径，点击确定按钮后，程序弹出识别结果。

OpenS-CAD, a simple 2D CAD application Have you ever wondered how a 2D CAD application is designed and implemented? I have, so I decided to sit down and write one. Now, implementing a fully functional 2D CAD is a tremendous task for a single person, and not something that can be completed in just a couple of months when only working on it on and off in the evenings. So, what I have implemented so far is the basic framework and only the most basic tools, but it does demonstrate how a CAD application could be implemented.

一个绘制三次B样条的类，可通过型值点计算控制点，可进行拆分，可计算拟合误差-a cubic B-spline drawing of the category, through point-value calculation control points can be split, translate fitting error

OpenGL实现立方体，OpenGl动画主要是通过提供的双缓存实现，经过调试-OpenGL to achieve cube, OpenGl animation is mainly through the provision of double-buffering to achieve, after debugging
