本文实例为大家分享了OpenCV实现图像转换为漫画的具体代码，供大家参考，具体内容如下

From 《OpenCV By Example》

1、先canny提取图像的边缘并强化，翻转边缘为黑色，将像素值转换为0-1的值

2、将图像进行双边滤波处理，然后将像素值缩短为每10个灰度级为一个值

3、将前两步得到的结果相乘，显示结果

#include "opencv2/imgproc.hpp"

using namespace cv;

int main()

{

Mat img = imread("1.jpg");

float radius = img.cols > img.rows ? (img.rows / 3) : (img.cols / 3);

Mat imgCanny;

Canny(imgMedian, imgCanny, 50, 150);

// Dilate the edges

Mat kernel = getStructuringElement(MORPH_RECT, Size(2, 2));

dilate(imgCanny, imgCanny, kernel);

// Scale edges values to 1 and invert values

imgCanny = imgCanny / 255;

imgCanny = 1 - imgCanny;

// Use float values to allow multiply between 0 and 1

// Apply bilateral filter to homogenizes color

Mat imgBF;

bilateralFilter(img, imgBF, 9, 150.0, 150.0);

// truncate colors

Mat result = imgBF / 25;

result = result * 25;

/** MERgES COLOR + EDgES **/

// Create a 3 channles for edges

Mat imgCanny3c;

Mat cannyChannels[] = { imgCannyf, imgCannyf, imgCannyf };

multiply(resultf, imgCanny3c, resultf);

// cout << resultf << endl;

// convert to 8 bits color

resultf.convertTo(result, CV_8UC3);

// Show image

imshow("Result", result);

waitKey(0);

return 0;
