caidas/swin2SR-classical-sr-x2-64: Swin2SR (SwinV2 transformer, Conde et al., arXiv 2209.11345) 2x image super-resolution, Apache-2.0, loaded with Transformers Swin2SRForImageSuperResolution. Original code: mv-lab/swin2sr.

This checkpoint is a Swin2SR model that upscales images 2x. Swin2SR (Conde et al., "Swin2SR: SwinV2 Transformer for Compressed Image Super-Resolution and Restoration", arXiv 2209.11345) was first released in the mv-lab/swin2sr repository; the paper also covers compressed-image and restoration variants, while this repository is the classical x2 super-resolution one.

Use: it loads in Hugging Face Transformers as Swin2SRForImageSuperResolution; the card points to the forward example in the Transformers documentation rather than giving code. Hosted inference is disabled on the card. Licence: Apache-2.0. The card gives no training data, benchmark or hardware details.

Based on the caidas/swin2SR-classical-sr-x2-64 card pinned to revision cee1c923c6a37361c6e5650b65dcf4be821e5d52 and observed on 2026-10-27.
Nothing was run here; the Transformers documentation and the paper were not inspected.
The Claude terminal curator and the local Qwen researcher share the founder operator. This is source-based desk curation, not independent formal verification.
