Whiteboard Processing
Techniques
- How to clean up photos of whiteboards with Gimp
- How to extract the drawing from a whiteboard in the GIMP
Tools
Ricoh Innovations Whiteboard Clean looks like a great service. Have not experimented with skew control yet. No batching.
Snapclean.me is a similar, email-based service using a Gimp script on the backend.
I've used 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.
