Steering One-Step Diffusion Model with Fidelity-Rich Decoder for Fast Image Compression

AAAI 2026technical

Diffusion-based image compression has demonstrated impressive perceptual performance. However, it suffers from two critical drawbacks: (1) excessive decoding latency due to multi-step sampling, and (2) poor fidelity resulting from over-reliance on generative priors. To address these issues, we propo

OSCAR: One-Step Diffusion Codec Across Multiple Bit-rates

NeurIPS 2025poster

Pretrained latent diffusion models have shown strong potential for lossy image compression, owing to their powerful generative priors. Most existing diffusion-based methods reconstruct images by iteratively denoising from random noise, guided by compressed latent representations. While these approac…

Regressive Domain Adaptation for Unsupervised Keypoint Detection

CVPR 2021poster

Domain adaptation (DA) aims at transferring knowledge from a labeled source domain to an unlabeled target domain. Though many DA theories and algorithms have been proposed, most of them are tailored into classification settings and may fail in regression tasks, especially in the practical keypoint d…
