| === Tools ===
| |
| | |
| [http://beta.rii.ricoh.com/betalabs/content/whiteboard-clean Ricoh Innovations Whiteboard Clean] looks like a great service. Have not experimented with skew control yet. No batching.
| |
| | |
| One of the challenges with this and other scripts is that it focuses on outlines, which means that filled images sometimes get processed out. May want to find a script that does background whitening for these images.
| |
| | |
| [http://snapclean.me/ Snapclean.me] is a similar, email-based service using a Gimp [https://github.com/kyleburton/sandbox/blob/master/gimp/clean-whiteboard-photo.scm script] on the backend.
| |
| | |
| I've used [http://www.fmwconcepts.com/imagemagick/whiteboard/index.php Fred's command-line Imagemagick script] with the following parameters:
| |
| | |
| -e both -t 30 -s 1
| |
| | |
| Experiment with -t between 20 and 40 for best results. It has limitations, the biggest of which is that you need to have a deeper understanding of the algorithm in order to manipulate the parameters.
