Deskew Text images (using Leptonica)

We just deskewed all over the place.

Installation

brew install leptonica
git clone [email protected]:TyGuy/deskew_text.git

Usage:

make clean && make
# ./deskew <filename_base>
# NOTE: .png file extension is assumed, don't add it
./deskew sample_image

Dev:

real simple, just edit files, run make, then the executable.

TODO:

Make usage easier:

• don't assume png, make it so you pass in full file name, and just ensure it's a raster image.
• print more helpful text
• let user customize it more (right now skew angle assumed between -45 and 45 degrees)

Other Ideas:

• de-warp
• use otsu threshold for binarization instead of
