# Emily Gorcensky's "obnoxious" fizz-buzz (less-compact version) annotated for non-python geeks.
# Explanation via Twitter: https://twitter.com/EmilyGorcenski/status/1228407309656903680?s=20
# If you want to dive into the meanings of how it works: it models fizzbuzz by
# computing the isomorphism of the finite cyclic groups of the values of the
# fizzes and buzzes and whatnot.
#
# These abelian groups are mapped to the unit circle in the complex plane and
# Represented as roots of unity. Such a interpetation has a polynomial
# representation. Therefore, the cartesian product in the isomorphism is
# represented as polynomial multiplication.  The coefficients of a Polynomial

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
