🐾 PAWS: Practical Video Super-Resolution

PAWS is a modular video super-resolution framework for training, evaluating, publishing, and running practical VSR models. This model repository hosts PAWS RealBasicVSR++ weights for x4 real-world video super-resolution, including the recommended HAT-LPIPS-TRes model and supporting ablation checkpoints.

For setup, inference commands, configuration details, and app usage, see the PAWS code repository:

📦 Model Files

File	Model	Format	Use
PAWS_RealBasicVSRPP_HAT_Stage2_LPIPS_TRes_REDSx4_G_EMA.pth	PAWS RealBasicVSR++-HAT-LPIPS-TRes	Raw EMA generator weights	Recommended research/inference checkpoint for test.py
PAWS_RealBasicVSRPP_HAT_Stage2_LPIPS_TRes_REDSx4_G_EMA.paws.pth	PAWS RealBasicVSR++-HAT-LPIPS-TRes	Published PAWS app artifact	Portable model for the demo app loader
PAWS_RealBasicVSRPP_HAT_Stage1_PSNR_REDSx4_G_EMA.pth	PAWS RealBasicVSR++-HAT-Stage1-PSNR	Raw EMA generator weights	Pre-GAN checkpoint
PAWS_RealBasicVSRPP_HAT_Stage2_LPIPS_TAvg_REDSx4_G_EMA.pth	PAWS RealBasicVSR++-HAT-LPIPS-TAvg	Raw EMA generator weights	Stage 2 ablation
PAWS_RealBasicVSRPP_HAT_Stage2_DISTS_REDSx4_G_EMA.pth	PAWS RealBasicVSR++-HAT-DISTS	Raw EMA generator weights	Stage 2 ablation
PAWS_RealBasicVSRPP_HAT_Stage2_LPIPS_SpatialD_REDSx4_G_EMA.pth	PAWS RealBasicVSR++-HAT-LPIPS-SpatialD	Raw EMA generator weights	Stage 2 ablation

EMA files are raw generator weights for test.py and research workflows. The .paws.pth file is a portable artifact created with tools.publish_model for the PAWS demo app. Only the recommended LPIPS-TRes model is released in the app artifact format.

🚧 Limitations

• The released models target x4 super-resolution.
• Results depend on the degradation patterns present in the input video.
• The models may hallucinate high-frequency texture under severe degradation.
• Large inputs may require tiled inference to fit available GPU memory.
