Description

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"

My favorite command line options and best practices

• Bash/zsh completion
• use Tab to populate command line, narrows down options as you go, fills in container names, ID's, images, volumes. Huge time saver.
