1、测试代码
void Laplacian( InputArray src,
OutputArray dst,
int ddepth,
int ksize = 1,
double scale = 1, double delta = 0,
int borderType = BORDER_DEFAULT );
void test11() {
Mat src = imread("D:/hf.jpg");
imshow("src", src);
Mat gray, dst;
cvtColor(src, gray, CV_BGR2GRAY);
imshow("gray", gray);
Laplacian(gray, dst, gray.depth(),3,1,0,BORDER_DEFAULT);
imshow("dst3", dst);
}
src
gray
dst
