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"

This file contains code that, when run on Python 2.7.5 or earlier, creates
a string that should not exist: u'\Udeadbeef'. That's a single "character"
that's illegal in Python because it's outside the valid Unicode range.

It then uses it to crash various things in the Python standard library and
corrupt a database.

On Python 3... well, this file is full of syntax errors on Python 3. But
if you were to change the print statements and byte literals and stuff:
