Find the native resolution(s) of upscaled material (mostly anime)

Start by executing:

$ getnative [--args] inputFile

If getnative could not be found, try executing this:

# Linux
$ python -m getnative [--args] inputFile

# Windows
$ py -3 -m getnative [--args] inputFile

or

Start by executing:

$ python -m getnative [--args] inputFile

That's it.

To run this script you will need:

• Python 3.6
• matplotlib
• Vapoursynth R45+
• descale
• ffms2 or lsmash or imwri
  *imwri: ImageMagick7 is required for macOS and Linux

Install it via:

$ pip install getnative

or

• Download all files from github
• Install all dependencies through pip install -r requirements.txt

Install these programs from their websites:

• Vapoursynth (includes imwri)

Once Vapoursynth is installed:

vsrepo.py install descale
vsrepo.py install ffms2
vsrepo.py install lsmas

Install getnative (and Python dependencies):

pip install getnative

Input Command:

$ getnative -k bicubic -b 0.33 -c 0.33 -dir "../../Downloads" "../../Downloads/unknown.png"

Terminal Output:

Using imwri as source filter

500/500

Output Path: /Users/infi/Downloads/results

This script's success rate is far from perfect. If possible, do multiple tests on different frames from the same source. Bright scenes generally yield the most accurate results. Graphs tend to have multiple notches, so the script's assumed resolution may be incorrect. Also, due to the current implementation of the autoguess, it is not possible for the script to automatically recognize 1080p productions. Use your eyes or anibin if necessary.
