This simple script will take a picture of a whiteboard and use parts of the ImageMagick library with sane defaults to clean it up tremendously.
The script is here:
#!/bin/bash
convert "$1" -morphology Convolve DoG:15,100,0 -negate -normalize -blur 0x1 -channel RBG -level 60%,91%,0.1 "$2"
| #!/bin/bash -e | |

| # Purpose: Pack a Chromium extension directory into crx format | |
| if test $# -ne 2; then | |
| echo "Usage: crxmake.sh <extension dir> <pem path>" | |
| exit 1 | |
| fi | |
| dir=$1 |
