Open CV : Program to display an image

Now I will show a program to display an image with C++ in OpenCV.

Open a new project in Visual C++ and open a Win32 console program file. Add the required library file as I have shown in my previous post.
Here is a program to read a picture file from a location in your system and display the picture.

Add the required header files as shown below and execute the program by pressing F5 .


Here I am showing the output of the above program.



Now you have understood the basics of running a OpenCV program with Visual C++.
I will explain more in coming posts.Stay with me....
