LibreRealESRGANx4-restore
RRDBNet Real-ESRGAN super-resolution (4x upscaling), repackaged for LibreYOLO.
Source
Weights derived from xinntao/Real-ESRGAN
release RealESRGAN_x4plus.pth.
Copyright (c) 2021 Xintao Wang. Licensed under the BSD 3-Clause License.
The RRDBNet architecture lineage is XPixelGroup/BasicSR (Apache-2.0, Copyright 2018-2022 BasicSR Authors).
Modifications
State-dict metadata-wrap only: keys and learned parameters are unchanged; the
checkpoint is wrapped in the LibreYOLO v1.0 schema (task=restore, scale=4).
Tensor-level parity vs the official model is exact (max_abs_diff == 0, fp32).
See weights/convert_realesrgan_weights.py in the
LibreYOLO source repository.
Usage
from libreyolo import LibreYOLO
model = LibreYOLO("LibreRealESRGANx4-restore.pt")
res = model.predict("small.jpg") # res[0].restored is 4x the input
res[0].save("upscaled.png")
# large images: model.predict("big.jpg", tile=512) # seam-free tiling
