Command line method for digitizing photos of whiteboards

About a month ago, after searching for an existing solution, I built a little script to take photo's of whiteboards and clean them up/make them into near perfect digital representations. Here's the script: #!/bin/bash convert $1 -morphology Convolve DoG:15,100,0 -negate -normalize -blur 0x1 -channel RBG -level 60%,91%,0.1 $2 Example Input: Input 1: http://i.imgur.com/CTSIPwm.jpg Input 2: http://i.imgur.com/37GXrwo.jpg Example Output: Output 1: http://i.imgur.com/Qf3jkBW.png Output 2: http://i.imgur.com/oNueb0L.png The basic procedure was outlined in this excellent post for cleaning up whiteboard photos using GIMP: http://matthew.mceachen.us/blog/how-to-clean-up-photos-of-whiteboards-with-gimp-403.html I just replicated the procedure using Imagemagick. Since I do a ton of work on whiteboards nearly every day, I found this really helpful for managing photos of my whiteboard work. I figured I should share this with you guys, since the HN community seems like the kind of people who'd make use of it.
