灰度图像边缘检测

图像融合（可视水印）源代码-source code for image fusion (visible watermarking)

把特定格式的3D模型显示出来，并且能用键盘和鼠标控制。3D文件已包含在压缩包里（abc.obj。-The specific format of 3D model is displayed, and can use the keyboard and mouse control. 3D document has been included in the compression bag (abc.obj.

本程序可实现快速Fourier变换，使用可直接调用-this procedure allows for fast Fourier transform, the use of direct call

利用FFT加窗并对信号进行插值，从而检测谐波。是一种快捷优良的算法，注释很详细，只需要改动一部分即可，谢谢！

因为VTK可视化工具包具有的强大的功能，可视化领域的研究人员很多都在应用它。本压缩包是在VC下编写的一个使用vtk实现平面生成的例程。-Because the VTK visualization toolkit with powerful functionality, visualization research in the field of personnel and many of them in the application of it. The compressed packet is prepared with a VC using VTK realize plane generated routines.
