How to dewarp an image?

Hello, I made a thermogram of one face of a cube, from 45 degrees angle. Therefore, the face does not results on the picture as a square, but it looks like a trapeze. I would like to dewarp such image in order to get the square-shape back. How can I do it? Thanks everybody!
