2. 均值滤波、Canny滤波

图像的均值滤波与canny变换

#include <opencv2/opencv.hpp> 
using namespace cv;

int main()
{
	//载入原始图
	Mat srcImage = imread("1.jpg");

	//显示原始图
	imshow("【原图】", srcImage);


	// 灰度图
	Mat grayImage;
	cvtColor(srcImage, grayImage, COLOR_BGR2GRAY);

	// blur滤波
	Mat edge;
	blur(grayImage, edge, Size(3, 3));

	// 运行Canny算子
	Mat canny;
	Canny(edge, canny, 3, 9, 3);

	imshow("【canny图】", canny);

	waitKey(0);
}
