What is Rule 110?

Rule 110 is an algorithm for a cellular automaton. The automaton works on of an infinite tape of 1s and 0s. It has a write head that can write to a specific position on the tape, and a read head that reads the position under the write head as well as the positions to either side. The set of three values read determines the value written by the write head according to the following rules:

Values Read	111	110	101	100	011	010	001	000
Value Written	0	1	1	0	1	1	1	0

If you notice, the value to write for each set of three values read corresponds to the position of the bits in the binary representation of the number 110. Hence, the name of the rule. Wikipedia has more information here.

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"
