This app 'keystone corrects' a given image. Basically, it straightens merging lines to correct perspective as expected in photos of tall buildings, snapshots of display boards shot at an angle, etc. A discussion of the algorithm behind this app is given here: https://jkmsmkj.wordpress.com/2013/07/27/projective-transformations .
Any feature suggestions or comments are welcome. Thanks for trying the app (if you did, that is) and enjoy (the life, in general)!
