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);*/}
