How To Use
Install libraries
A record is kept in requirements.txt, and can be installed with:
pip install -r requirements.txt
However, after doing this, you must also install image slicer with:
pip install -e submodules/image_slicer
And also install BasicSR with:
pip install -e submodules/BasicSR
Download anime model:

For a single image:
python3 frame_esrgan.py -m /path/to/RealESRGAN_x4plus_anime_6B.pth -i path/to/img -o path/to/img.png
If memory usage is too high and you need to split frames and stitch back together use the -s, --split argument. Default number of splits is 4, but you can make as many as you want.
If you want to change the final size, one can now add the -r or the --resize argument, followed by a string indicating the desired resolution, for example we would add -r 1920x1080 to resize the output to that size.
Please note that the output of a single image must be a PNG due to alpha channel. Will be fixed in the future hopefully
For a video:
python3 anime_upscaler.py -m /path/to/RealESRGAN_x4plus_anime_6B.pth -i path/to/video -o path/to/desired/output -s -a
If you do not want audio, remove the -a at the end
