Affine-StableSR: Coupling Layer-based Lightweight Autoencoder and Stable Diffusion Model for Image Super-Resolution

Affine-StableSR is a compact and efficient super-resolution model that leverages pre-trained Stable Diffusion weights and normalizing-flow coupling layers to reduce parameter count while maintaining performance. The lightweight autoencoder based on affine coupling layers is combined with a frozen diffusion prior for image super-resolution.
