射线追踪算法的基础理论和学习，入门课件，适用于地震学(The basic theory and learning of ray tracing)

说明：  编程实现灰度图像的频域滤波算法。使用Matlab实现不延拓和延拓两个版本。对于延拓和不延拓版本，在理想低通滤波器、巴特沃斯低通滤波器和高斯低通滤波器上比较两者的区别；对于延拓版本，比较不同参数设置对上述三种滤波器滤波结果的影响。(Program to realize the filtering algorithm of gray image in frequency domain. Matlab is used to realize two versions of no extension and extension. For the extension version and the non extension version, the differences between the ideal low-pass filter, Butterworth low-pass filter and Gauss low-pass filter are compared; for the extension version, the effects of different parameter settings on the above three filter results are compared.)

说明：  小波去噪的程序，很好用，推荐给大家使用。(Wavelet denoising procedures, very easy to use, recommended for everyone to use)

introduce 3d with dx9.0 绝好的3d书籍加源码(introduce 3d with dx9.0 excellent books on Canadian source 3d)

一个非常好的粗糙集的代码-希望对大家学习提供参考(Rough set a very good code- I hope to provide reference for all of us to learn)

一个简单的windows TDI框架,通过他可以熟悉TDI框架模型(A simple windows TDI framework through which he can familiarize himself with the TDI framework model)

说明：  机械臂正解反解程序仿真程序 开源，自己可以设置6个角度 然后会得出相应的变化数据和图像。(Positive Solutions of inverse manipulator program simulation)

说明：  用小波的方法对图像进行二值化操作÷ 效果不错(wavelet methods of image binarization good operating results )
