HyperTextHero: Digitizing Photos of Whiteboards Using the Command Line

Make sure you have ImageMagick installed.
Save the following somewhere such as ~/code/whiteboardClean.sh and don’t forget to make it executable with chmod +x ~/code/whiteboardClean.sh:

:::bash #!/bin/bash convert $1 -morphology Convolve DoG:15,100,0 -negate -normalize -blur 0x1 -channel RBG -level 60%,91%,0.1 $2
Add an alias to the above in your ~/.bashrc:

:::bash alias wbclean="~/code/whiteboardClean.sh"
To convert photo of a whiteboard to a cleaner diagram of the same you can now do:

:::bash cd /location/of/photo.jpg wbclean photo.jpg diagram.png
