Load & Display Image using OpenCV

Let's start to create our first project!

1. Open OpenCV workspace: Click Start-->All Programs-->OpenCV-->OpenCV Workspace MSVC6
2. Create new C++ source file: Click File-->New-->C++ Source File. Put the file name & the folder. Now you have a blank editor to write the code.
3. Write the following code:

#include "cv.h" //main OpenCV header
#include "highgui.h" //GUI header

int main() {
// declare a new IplImage pointer
IplImage* myimage;

// load an image
myimage = cvLoadImage("sayyidsmile.jpg",1); //change the file name with your own image

//create a new window & display the image
cvNamedWindow("Smile", 1);
cvMoveWindow("Smile", 100, 100);
cvShowImage("Smile", myimage);

//wait for key to close the window
cvWaitKey(0);
cvDestroyWindow( "Smile" );
cvReleaseImage( &myimage );
return 0;

}

4. Add library in the project setting: Click Project-->Setting-->Link-->Object/Library Modules then write cv.lib cvaux.lib cxcore.lib highgui.lib. Make sure that you do this step anytime you create a new project.
5. Save and click "Execute Program" icon, then your window named "Smile" will appear.
