这篇文章主要为大家详细介绍了使用OpenCV怎么将彩色照片转换成素描卡通照片,文中示例代码介绍的非常详细,具有一定的参考价值,发现的小伙伴们可以参考一下:
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;
}
