学习OpenCV——用OpenCv画漫画

 

闲的时候用OpenCV画漫画也挺有意思，虽然效果不好（达不到上面所实现的效果），

参数需要调整，还是大头贴而且噪声小的图像比较合适

而且可以熟悉一下关于各种滤波的操作比如：双边滤波；

#include "cv.h"
#include "highgui.h"

using namespace cv;
using namespace std;

int main()
{
	string name="D:/cartoon0.jpg";
	Mat src1=imread(name,1);
	Mat img;
	//双边滤波，第3个参数d可以说d>5时不能实时处理，最后两个参数是sigma参数，一般相同，
	//<10时基本没效果, >150时漫画效果
		bilateralFilter(src1,img,5,150,150);
		bilateralFilter(img,src1,5,150,150);
		//img.copyTo(src1);
	
	imshow("bilateral",src1);
	waitKey(0);
		
	Mat src;
	cvtColor(src1,src,CV_BGR2GRAY);
	//粗线，越大越粗，但是会有大量噪点
	Mat imgL;
	//第三个参数ddepth表示目标图像的深度，ddepth=-1时，与原图像一致
	Laplacian(src,imgL,-1,3,1);
	imshow("Laplacian",imgL);
	waitKey(0);
	//细线
	Mat imgC;
	Canny(src,imgC,30,90);
	imshow("Canny",imgC);
	waitKey(0);

	Mat imgS,imgSx,imgSy,imgS0;
	Sobel(src,imgSx,-1,0,1);
	Sobel(src,imgSx,-1,1,0);
	imgS=imgSx+imgSy;
	Sobel(src,imgS0,-1,1,1);
	imshow("Sobel0",imgS0);
	imshow("Sobel",imgS);
	waitKey(0);
	
	Mat imgTotal;
	imgTotal=imgC+imgS+imgL;
	//imgTotal.convertTo(imgTotal,CV_32FC1);
	normalize(imgTotal,imgTotal,255,0,CV_MINMAX);
	GaussianBlur(imgTotal,imgTotal,Size(3,3),3);
	threshold(imgTotal,imgTotal,100,255,THRESH_BINARY_INV);
	imshow("Total",imgTotal);
	waitKey(0);

	Mat imgTotalC3;
	cvtColor(imgTotal,imgTotalC3,CV_GRAY2BGR);
	bitwise_and(src1,imgTotalC3,src1);
	imshow("Result",src1);
	waitKey(0);

	
	name.insert(11,"_edge");
	imwrite(name,src1);

	/*
	Mat img(imgTotal.rows,imgTotal.cols,CV_32FC1);
	for(int i=0;i<imgTotal.rows;i++)
	{
		//uchar* p=(uchar*)(imgTotal.ptr()+i*imgTotal.step);
		for(int j=0;j<imgTotal.cols;j++)
		{
			if(imgTotal.at<float>(i,j)==0)
				img.at<float>(i,j)=1;
		}
	}
	imshow("Reverse",img);
	waitKey(0);
	*/
	/*
	Mat imgSc;
	Scharr(src,imgSc,-1,1,0);
	imshow("Scharr",imgSc);
	waitKey(0);
	*/
