I managed to scaled down a 640x480 pixels to 8x4 using the cv::Resize function, but as expected it will display a 8x4 window size right?

Now, I resized the window to a bigger size, but the image is still at 8x4pixels. I want it to fit on the bigger size.

Check my code below. image description

Resizewindow only changes the size of the displaying window, not the image that it displays. If you want to resize the image, call resize again with your size variable modified to the new dimensions. Although I fail to see the reason behind that... increasing an image from 8x4 to 260x150 and changing the aspect ratio.

this for the display purposes only. I just want the 8x4pixels to be shown on a bigger window. So there is no other way I can achieve this?

NOW I understand your problem... you used the methods in the wrong order. First, you declare your window with cvNamedWindow, then you use ShowImage and after that resize (or before, doesn't matter). The important thing is to always use namedwindow first.
