What is StableSR?
StableSR is an advanced image super-resolution model that builds upon Stable Diffusion technology. It introduces innovative features like time-aware encoding and controllable feature wrapping (CFW) to achieve high-quality image upscaling. The model has been specifically designed to handle real-world image super-resolution tasks with remarkable effectiveness.
Implementation Details
The model architecture combines multiple sophisticated components: a fixed autoencoder that transforms images into latent representations (with an 8x downsampling factor), a time-aware encoder for guidance, and a CFW module trained on synthetic paired data. The model offers multiple checkpoints, including variants optimized for different resolutions and a turbo version capable of 4-step sampling.
