{
char *path = "C:\\OpenCV\\images\\lena.jpg";
Mat image;
// 載入圖檔
image = imread(path, CV_LOAD_IMAGE_COLOR);
// 檢查讀檔是否成功
if(! image.data )
{
cout << "無法開啟或找不到圖檔" << std::endl ;
return -1;
}
namedWindow("original image", CV_WND_PROP_AUTOSIZE);
imshow("original image", image);
//-------------------------------------
int numPts = 10000;
AddNoise(image, numPts);
namedWindow("image with noise", CV_WND_PROP_AUTOSIZE);
imshow("image with noise", image);
waitKey(0);
getchar();
return 0;
}
Distance Transform [2]經常應用在二值影像，其運算結果則為一灰階影像，
