本文实例为大家分享了OpenCV实现彩色照片转换成素描卡通片的具体代码，供大家参考，具体内容如下

#include"stdafx.h"//#include<cv.h>//#include<highgui.h> #include <opencv2/highgui/highgui.hpp>#include <opencv2/imgproc/imgproc.hpp>#include <opencv2/core/core.hpp>using namespace cv;using namespace std; int main(){ Mat src,smallImg,tmp,bigImg,gray,edges,masks,dst; const int MEDIAN_BLUR_FILTER_SIZE = 7; const int LAPLACIAN_FILTER_SIZE = 5; const int EDGES_THRESHOLD = 80; int repetitions = 7; // Repetitions for strong cartoon effect. src = imread("pic.jpg"); Size size = src.size(); Size smallSize; smallSize.width = size.width/2; smallSize.height = size.height/2; smallImg = Mat(smallSize, CV_8UC3); tmp = Mat(smallSize, CV_8UC3); dst= Mat(size,CV_8UC3); cvtColor(src,gray,CV_BGR2GRAY); medianBlur(gray,gray,MEDIAN_BLUR_FILTER_SIZE); Laplacian(gray, edges, CV_8U,LAPLACIAN_FILTER_SIZE); threshold(edges, masks,EDGES_THRESHOLD,255, THRESH_BINARY_INV); imshow("sketch:)", masks); waitKey(10); resize(src, smallImg, smallSize, 0,0, INTER_LINEAR); for (int i=0; i<repetitions; i++) { int ksize = 9; // Filter size. Has a large effect on speed. double sigmaColor = 9; // Filter color strength. double sigmaSpace = 7; // Spatial strength. Affects speed. bilateralFilter(smallImg, tmp, ksize, sigmaColor, sigmaSpace); bilateralFilter(tmp, smallImg, ksize, sigmaColor, sigmaSpace); } resize(smallImg, bigImg, size, 0,0, INTER_LINEAR); bigImg.copyTo(dst,masks); imshow("cartoon :)", dst); waitKey(0); return 0;}

原图、素描图、卡通图效果依次为：
