REMOVING FISHEYE DISTORTION

visitor [alex] had a industrial plugin for fisheye lens adjustment as well as wondered precisely what type of magic was behind it. Was it really doing line detection? He dropped in a square grid to see what it spit out. The warped result suggested that the change was totally independent of the photo’s content. utilizing this result as a guide he was able to produce a similar transform utilizing Warp as well as save it as a script. The script produces practically similar results as well as now he understands precisely exactly how bit magic is involved.
