2014電腦圖學A: week06

程式碼：
#include<opencv/highgui.h>
int main()
{
IplImage * img = cvLoadImage("earth.jpg"); //宣告變數讀入影像
cvNamedWindow("week06"); //命名視窗名字
cvShowImage("week06",img); //顯示影像
cvWaitKey(0); //暫停

}

*Dev c++：工具→編譯器選項→將連結器命令列中加入以下命令輸入"-lcv -lcxcore -lhighgui"

將Dev-Cpp >> bin >> opencv << 複製所有.dll檔至專案資料夾中
