Definition: A virtual or physical representation of having accomplished something. These are often viewed as rewards in and of themselves.

Example: a badge, a level, a reward, points, really anything defined as a reward can be a reward.

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
