The paper and project describe model architecture, degradation synthesis, and inference options; output is an estimate rather than recovered evidence.
Real-ESRGAN (Wang et al., 2021) studies blind super-resolution using pure synthetic data. Its high-order degradation process chains several blur, noise, resizing, and compression operations, including sinc filters for ringing and overshoot artifacts. The generator retains ESRGAN’s RRDB blocks; the paper describes a U-Net discriminator with spectral normalization. The official repository lists general and anime-oriented models and supports tiled inference. Separately, GFPGAN documents Real-ESRGAN as a default background upsampler in its inference script. That documented configuration is not evidence of common usage or a guarantee of face-restoration quality. Generated detail is an estimate, not recovered source information.
Paper method: chain blur, noise, resizing, and compression during degradation synthesis.
Repository feature: general-photo and anime-oriented checkpoints are listed separately.
Repository feature: tiled inference can lower peak memory for large inputs, with boundary handling to consider.
GFPGAN repository: its documented inference command uses Real-ESRGAN as a background upsampler; this is one stated integration option.
Evaluate restoration against the target degradation and image type, checking identity preservation and hallucinated details. Report checkpoint, scaling factor, tile settings, and visual limitations. Avoid treating a sharper output as proof of an image’s original content.
