Opencv学习八（模糊图像）

#include<opencv2/opencv.hpp>
#include<iostream>

using namespace cv;

int main(int argc, char** argv)
{
	Mat src, dst;
	src = imread("1.jpg");
	if (!src.data)
	{
		printf("无\n");
		return -1;
	}
	char input_title[] = "input image";
	char output_title[] = "blur image";
	namedWindow(input_title, WINDOW_FREERATIO);
	namedWindow(output_title, WINDOW_FREERATIO);
	imshow(input_title, src);

	blur(src, dst, Size(5, 5), Point(-1, -1));//均值模糊
	imshow(output_title, dst);

	Mat gblur;
	GaussianBlur(src, gblur, Size(15, 15), 11, 11);//高斯模糊
	                    // Size必须为正值且奇数
	namedWindow("gaussianblur", WINDOW_FREERATIO);
	imshow("gaussianblur", gblur);

	waitKey(0);
	return 0;
}

双边滤波和中值滤波

#include<opencv2/opencv.hpp>
#include<iostream>

using namespace cv;

int main(int argc, char** argv)
{
	Mat src, dst;
	src = imread("1.jpg");
	if (!src.data)
	{
		printf("无\n");
		return -1;
	}
	namedWindow("input image", WINDOW_FREERATIO);
	imshow("input image", src);
	
	//medianBlur(src, dst, 3);  //中值滤波(去噪点)
	bilateralFilter(src, dst, 15, 150, 3);//双边滤波
	namedWindow("median Filter Result", WINDOW_FREERATIO);
	imshow("median Filter Result", dst);

	waitKey(0);
	return 0;
