New diffusion models tackle image super-resolution with wavelet and latent space innovations
ByPulseAugur Editorial·[9 sources]·
Researchers have developed two new frameworks, SlimDiffSR and TOC-SR, to make diffusion models more efficient for image super-resolution tasks. SlimDiffSR focuses on remote sensing imagery by using a distilled teacher model and structured pruning techniques, achieving up to a 200x inference acceleration and a 20x reduction in parameters. TOC-SR creates compact diffusion backbones through feature-wise distillation and architecture discovery, resulting in a 6.6x parameter reduction and a 2.8x reduction in GMACs before distilling into a single-step generator. Both approaches aim to balance high reconstruction quality with significantly reduced computational costs for practical deployment.
