opencv 图片清晰度判断代码

读取D盘里面的两张图片，进行清晰度的判别。
阈值可以自行修改

#include <highgui/highgui.hpp>
#include <imgproc/imgproc.hpp>using namespace std;
using namespace cv;int main()
{Mat imageSource = imread("D:/1.jpg");Mat imageGrey;cvtColor(imageSource, imageGrey, CV_RGB2GRAY);Mat imageSobel;Sobel(imageGrey, imageSobel, CV_16U, 1, 1);//图像的平均灰度double meanValue = 0.0;meanValue = mean(imageSobel)[0];//double to stringstringstream meanValueStream;string meanValueString;meanValueStream << meanValue;meanValueStream >> meanValueString;meanValueString = "Articulation(Sobel Method): " + meanValueString;putText(imageSource, meanValueString, Point(128, 128), CV_FONT_HERSHEY_COMPLEX, 4, Scalar(0, 255, 0), 3);namedWindow("Articulation", WINDOW_FREERATIO);imshow("Articulation", imageSource);Mat iimageSource = imread("D:/2.jpg");Mat iimageGrey;cvtColor(iimageSource, iimageGrey, CV_RGB2GRAY);Mat iimageSobel;Sobel(iimageGrey, iimageSobel, CV_16U, 1, 1);//图像的平均灰度double iimeanValue = 0.0;iimeanValue = mean(iimageSobel)[0];//double to stringstringstream iimeanValueStream;string iimeanValueString;iimeanValueStream << iimeanValue;iimeanValueStream >> iimeanValueString;iimeanValueString = "iArticulation(Sobel Method): " + iimeanValueString;putText(iimageSource, iimeanValueString, Point(128, 128), CV_FONT_HERSHEY_COMPLEX, 4, Scalar(0, 255, 0), 3);//照片/添加的文字/左上角坐标/字体/字体大小/颜色/字体粗细namedWindow("iArticulation", WINDOW_FREERATIO);imshow("iArticulation", iimageSource);if (meanValue - 3> iimeanValue)printf("超出阈值");elseprintf("未超出阈值");waitKey();
