This function creates a window with the name of " The Guitar". Otherwise your program will crash while trying to execute the imshow() function. It's a good practice to check whether the image is empty and exit the program. When the user press any key in the keyboard, the program will exit returning -1. In such scenarios, our program will print an error message to the console and wait for any key press. If the Mat object is empty, image.empty() function will return true. If imread() function fails to load the image, the returned Mat object will be empty.

IMREAD_COLOR - The image will be loaded as a BGR image (i.e.

Single channel image, Black and white image)

IMREAD_GRAYSCALE - The image will be load as a gray-scale image (i.e.

If you want to get the alpha channel in your input image (if it is available), you have to use this flag.

IMREAD_UNCHANGED - The image will be loaded as it is.

In the above program, I did not pass any value to this argument such that default IMREAD_COLOR argument will be used.

flags - There are several possible values for the flag argument.

Other image file types are supported depending on your platform and installed codecs. jpeg, jpg, bmp, png, tiff and tif image file types are always supported. If you are giving the relative path, it should be relative to your cpp file.

filename - You have to give the relative or absolute path of an image file.

If the function cannot read the file, it will return an empty Mat object. This function loads an image from the specified file and return is as a Mat object. In your code, you have to replace the " D:/My OpenCV Website/Lady with a Guitar.jpg" with a valid location to an image file in your computer. The function loads an image from the file " D:/My OpenCV Website/Lady with a Guitar.jpg" and returns it as a Mat object. We have to use the std namespace also because cout, endl and cin functions are inside the std namespace. For more information, please refer OpenCV C++ API. Otherwise we have to append 'cv::' specifier before each OpenCV functions, classes and data structures. So, we have to add the ' using namespace cv' line in the top of our program. Iostream header file should also be included because we use cout and cin in our program to print an error message to the console.Īll OpenCV functions, classes and data structures are declared inside cv namespace. You have to include only this header file in order to compile your OpenCV codes. Opencv2/opencv.hpp header file itself will include all other neccessary header files in OpenCV library. If you are using Visual Studio, please uncomment this line to avoid a compile error. This is the pre-compiled header file generated by Visual Studio IDE. Then you should see a output like the below image.
