StupidCensor
a REVERSABLE image censoring tool
to reversably mosiac censor jpeg files
to temporarily remove image details
not allowed on most websites like
nudity and/or censored speech, the
original image can be completely restored
without any quality loss but shouldn’t
be recognizable by most automated scanning
tools or the naked eye
How it works
It changes the quant tables to cause 8×8
blocks to render as a single color, basically
its full mosiac pixelation, but it saves the
original quant tables in the jpeg so if you
run the same tool on it again it restores those
tables and the full image is restored!
Unfinished
I’m thinking I might also allow for different
pixel sizes, because 8×8 is not very obscuring
for large images, but in order to do that it
will be far more challenging because I’ll have
to decompress/recompress all of the image data.
Warning
NOT INTENDED for sensitive, private, or
illegal data
The reversable censoring methods are simple, open,
and obvious. It will only deter casual viewers
and automated image scanners used for flagging
content or censorship.
Useful applications
Handy for sharing LEGAL pのrnのgrムphソ,
avoiding copyright issues, and sharing images
that might otherwise violate terms of service.
Allowing you to collaborate on ero-manga translation
projects on platforms that don’t otherwise allow
such content.
Requirements
Python3 with standard modules
Installation
Just move the stupidcensor.py into your path somewhere
and make sure it has run permission.
Usage
stupidcensor.py -h for basic options but generally
use:
stupidcensor.py yourjpgfile -o newjpgfile
this will create a mosiac censored copy of your image
run it again on the new file to reverse it
use the -i option if you want to overwrite the original
check stupidcensor.py -h for more options
