OpenCvSharp是一个跨平台的OpenCV的.NET框架包装，采用C#编写。您可以在C#，VB.NET中使用许多流行的图像处理和计算机视觉算法。

• OpenCvSharp wraps more OpenCV's functions than SharperCV and OpenCVDotNet.
• Many classes of OpenCvSharp implement IDisposable. You can write stylish code by "using" statement.
• OpenCvSharp does not force object-oriented programming style on you. You can also call native-style OpenCV functions.
• OpenCvSharp provides functions for converting from IplImage into Bitmap(GDI+) or WriteableBitmap(WPF).
• OpenCvSharp can work on Mono. Therefore it is able to run on any platform which Mono supports (e.g. Linux, BSD and Mac OS X).

using System;  using OpenCvSharp;    class Program   {      static void Main()       {          using (IplImage src = new IplImage("lenna.png", LoadMode.GrayScale))          using (IplImage dst = new IplImage(src.Size, BitDepth.U8, 1))           {              src.Canny(dst, 50, 200);              using (CvWindow window_src = new CvWindow("src image", src))               using (CvWindow window_dst = new CvWindow("dst image", dst))               {                  CvWindow.WaitKey();              }          }      }  }
