Revision history [back]

I am not sure if I am the only one facing this issue. But In my machine, images are not loading in OpenCV 4.x.x. I have tried 4.0.0 (prebuilt x64 Windows binaries), 4.1.1(prebuilt x64 Windows binaries) and 4.1.2(built x64 binaries from source using VS 2019).

Interestingly, the same code works for OpenCV 3.x.x.

Am I missing something?

#include <iostream>
#include <filesystem>
#include <opencv2/core.hpp>
#include <opencv2/highgui.hpp>
#include <opencv2/imgcodecs.hpp>
#include <opencv2/imgproc.hpp>


using namespace std;
using namespace cv;

int main(int argc, char* argv[])
{

    Mat image;
    string imagePath = filesystem::current_path().string() + "\\images\\road.jpg";

    cout << "Image Path : " << imagePath << "\n";

    image = imread(imagePath, IMREAD_COLOR);

    if (image.empty())
    {
        cout << "ERROR READING IMAGE!";
        return -1;
    }


    String windowTitle = "Hello OpenCV";
    namedWindow(windowTitle, WINDOW_AUTOSIZE);

    imshow(windowTitle, image);
    waitKey(0);

    return 0;
}

[ UPDATE ]

This issue is still unresolved. I have also asked it in the OpenCV forum Stack Overflow (here) but failed to get any solution. Thus, I have uploaded videos to explain the problem. So, Kindly take a look for clarification.
