Principle:AUTOMATIC1111 Stable diffusion webui LDSR Upscaler
Definition
VQ-VAE autoencoder architecture used by the LDSR super-resolution upscaler.
Motivation
The LDSR upscaler relies on a VQ-VAE autoencoder to encode images into a discrete latent space before applying latent diffusion for super-resolution. Providing this architecture as a dedicated component enables the LDSR upscaling pipeline to function as a self-contained image enhancement option within the WebUI.
