Picture Craziness

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"

Results

# systemctl start disable-transparent-huge-pages
# systemctl status disable-transparent-huge-pages
# cat /sys/kernel/mm/transparent_hugepage/enabled
