Unable to load images with imread in Visual Studio 2019
Hi guys,
I am trying to do the OpenCV tutorial " Load and Display an Image " however, when I run the code my image doesn't load and I get the "Could not open or find the image" - message. I have tried changing the path directory with the complete path to the image, but it doesn't help.
I am using OpenCV 4.1.0 and Visual Studio 2019. Any ideas what might be going wrong?
#include <opencv2/core.hpp>
#include <opencv2/imgcodecs.hpp>
#include <opencv2/highgui.hpp>
#include <iostream>
#include <string>
using namespace cv;
using namespace std;
int main(int argc, char** argv)
{
String imageName("Image002"); // by default
if (argc > 1)
{
imageName = argv[1];
}
Mat image;
image = imread(imageName, IMREAD_COLOR); // Read the file
if (image.empty()) // Check for invalid input
{
cout << "Could not open or find the image" << std::endl;
return -1;
}
namedWindow("Display window", WINDOW_AUTOSIZE); // Create a window for display.
imshow("Display window", image); // Show our image inside it.
waitKey(0); // Wait for a keystroke in the window
return 0;
}
Likely a path and/or extension issue. Try using an absolute path and check to see if the image file has an extension like .jpg, .png, etc. something like "c:/temp/image002.jpg"
