VS2008 WindowsForm + OpenCV

利用VS2008本身的視窗表單應用在OpenCV

1.

2.

3.因為出現了 

error C3862: 'cvRound': 不能以 /clr:pure 或 /clr:safe 編譯 Unmanaged 函式~ 所以加了這一步

要看詳細的話~請參看這個網址:

http://msdn.microsoft.com/zh-tw/library/ms235211%28v=vs.90%29.aspx

4. 在表單上拉元件  ~ 用PictureBox 跟 Button這兩個元件拉

5.拉一個正在關閉的事件

6. 執行結果畫面

程式碼:
