I made a simple GUI in python which essentially wraps OpenCV's getPerspectiveTransform/warpPerspective. It let's you select the four corners, chose an aspect ratio and do some simple postprocessing. I was working on edge detection, but it's not working well right now. I will try to put it on github.
