studiosr 0.1.5

Python library to accelerate super-resolution research

StudioSR

StudioSR is a Pytorch library providing implementations of training and evaluation of super-resolution models. StudioSR aims to offer an identical playground for modern super-resolution models so that researchers can readily compare and analyze a new idea. (inspired by PyTorch-StudioGan)

Installation

From PyPI

pip install studiosr

From source (Editable)

git clone https://github.com/veritross/studiosr.git
cd studiosr
python3 -m pip install -e .

Documentation

Documentation along with a quick start guide can be found in the docs/ directory.

Quick Example

$ python -m studiosr --image image.png --scale 4 --model swinir

from studiosr.models import SwinIR
from studiosr.utils import imread, imwrite

model = SwinIR.from_pretrained(scale=4).eval()
image = imread("image.png")
upscaled = model.inference(image)
imwrite("upscaled.png", upscaled)

Benchmark

• The evaluation metric is PSNR.
• "+" indicates the result of self-ensemble.
