Recognize rotated characters #1

Open kristianhentschel opened 9 years ago

Characters rotated by multiples of 90 degrees should still be recognized. Special notice should be given to ambiguous characters M and W.

Attempt 0: Try all four orientations, by copying the preprocessed image onto a new canvas for each, and running that through OCRAD, and use the confidence ratings provided by its verbose mode.

attempted with letter "E": confidence is 0 for all letters recognized at any orientation. Maybe confidence is only a relative value, if there are multiple matches for a single character, in that case it cannot help here.
