blitzdrt's Introduction

blitzDrt

Tool to correct perspective distortion

  • Does not correct verticals (column separators, table lines) yet.
  • Uses Blitz++ and ImageMagick++ library.
  • "drt" comes from "discrete radon transformation", the intermediate result when rotating the image by -x° to x° to find optimal deskewing angle for top and bottom of the page.

Installation

Requires ImageMagick++, libfft3, blitz and boost_program_options.

ImageMagick++, libfftw3 and boost_program_options can be installed with make deps-ubuntu.

If blitz is not available in your distro, you can build from source with make install-blitz (might require make install-cmake first for an up-to-date CMake).

Run make install to build and install the tool, it will be available as productiveDrt in your $PATH.

Uninstall with make uninstall

Usage

Example: ./productiveDrt --if input.png --of output.png --doTrans

Help: ./productiveDrt --help

Tries to detect if text is on page - to prevent deskewing of e. g. architectural plans or hatchings.

Warning: output files are not suitable for archival. Metadata could be lost (imagemagick).
