Jun 11, 2013 at 12:59 comment added Wandering Logic Your link doesn't give any relevant information. What is the "marker?" on the paper? What does the app do? Does it simply make sure that the blue line on graph paper are actually equally spaced vertical and horizontal lines in the resulting jpg? You might start by looking up "Hough transform" for one way to detect the lines and then "keystone effect" for the linear transformation you need to perform to make the lines parallel.
