學習OpenCV——用OpenCv畫漫畫

 

閑的時候用OpenCV畫漫畫也挺有意思，雖然效果不好（達不到上面所實現的效果），

參數需要調整，還是大頭貼而且雜訊小的映像比較合適

而且可以熟悉一下關於各種濾波的操作比如：雙邊濾波；

#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;//雙邊濾波，第3個參數d可以說d>5時不能即時處理，最後兩個參數是sigma參數，一般相同，//<10時基本沒效果, >150時漫畫效果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);//粗線，越大越粗，但是會有大量噪點Mat imgL;//第三個參數ddepth表示靶心圖表像的深度，ddepth=-1時，與原映像一致Laplacian(src,imgL,-1,3,1);imshow("Laplacian",imgL);waitKey(0);//細線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);*/}
