LUSD: Localized Update Score Distillation for Text-Guided Image Editing

ICCV 2025poster

While diffusion models show promising results in image editing given a target prompt, achieving both prompt fidelity and background preservation remains difficult. Recent works have introduced score distillation techniques that leverage the rich generative prior of text-to-image diffusion models to…

Diffusion Sampling with Momentum for Mitigating Divergence Artifacts

ICLR 2024poster

Despite the remarkable success of diffusion models in image generation, slow sampling remains a persistent issue. To accelerate the sampling process, prior studies have reformulated diffusion sampling as an ODE/SDE and introduced higher-order numerical methods. However, these methods often produce d…

DiffusionLight: Light Probes for Free by Painting a Chrome Ball

CVPR 2024poster

We present a simple yet effective technique to estimate lighting in a single input image. Current techniques rely heavily on HDR panorama datasets to train neural networks to regress an input with limited field-of-view to a full environment map. However these approaches often struggle with real-worl…
