Question

#include <iostream>
#include <opencv2/opencv.hpp>
 #include <opencv2/highgui/highgui.hpp>
#include <opencv2/imgproc/imgproc.hpp>

using namespace std;
using namespace cv;



 int main()
{
   // load the image

Mat img = imread("C:\\Users\\prashant naresh\\Documents\\Visual Studio      2010\\Projects\\nonlocalfilter\\image.jpg");


if(!img.data) {
    cout << "File not found" << endl;
    return -1;
}



// show it in a window
namedWindow( "Image", WINDOW_AUTOSIZE );
imshow("Image", img);

// image window will immediately disappear if the program ends, so
// we'll wait for a keypress, indefinitely
waitKey();

// do a simple transformation: convert to grayscale

// first copy the image
Mat img_gray = img.clone();
Mat img1;
cvtColor(img, img_gray, CV_RGB2GRAY);
fastNlMeansDenoising(img_gray,img1,3.0,7,21);
imshow("Image", img1);
waitKey();
return 0;
 }

ERROR：

Answer 1

好像你忘了链接opencv_photo249.lib //或者你正在使用的任何版本

Answer 2

你有一些链接问题。

再次尝试通过this过程使用Visual Studio配置Opencv 2.4.8或2.49。

希望这会对你有所帮助。干杯
