Correction Training for Diffusion Models

Donghoon Ahn, Runqian Wang, Alexei A. Efros +2

Iterative sampling in diffusion models can lead to error accumulation due to exposure bias. The denoiser is trained on real images interpolated with noise, but at inference its inp…

TAG: Tangential Amplifying Guidance for Hallucination-Resistant Sampling

Hyunmin Cho, Donghoon Ahn, Susung Hong +3

Diffusion models achieve state-of-the-art image generation but often produce semantic inconsistencies, or hallucinations. Existing inference-time guidance methods rely on external…

Vid-CamEdit: Video Camera Trajectory Editing with Generative Rendering from Estimated Geometry

Junyoung Seo, Jisang Han, Jaewoo Jung +9

We introduce Vid-CamEdit, a novel framework for video camera trajectory editing, enabling the re-synthesis of monocular videos along user-defined camera paths. This task is challen…

Where and How to Perturb: On the Design of Perturbation Guidance in Diffusion and Flow Models

Donghoon Ahn, Jiwon Kang, Sanghyun Lee +7

Recent guidance methods in diffusion models steer reverse sampling by perturbing the model to construct an implicit weak model and guide generation away from it. Among these approa…

Identity-preserving Distillation Sampling by Fixed-Point Iterator

SeonHwa Kim, Jiwon Kim, Soobin Park +5

Score distillation sampling (SDS) demonstrates a powerful capability for text-conditioned 2D image and 3D object generation by distilling the knowledge from learned score functions…

A Noise is Worth Diffusion Guidance

Donghoon Ahn, Jiwon Kang, Sanghyun Lee +9

Diffusion models excel in generating high-quality images. However, current diffusion models struggle to produce reliable images without guidance methods, such as classifier-free gu…

Geometry-Aware Score Distillation via 3D Consistent Noising and Gradient Consistency Modeling

Min-Seop Kwak, Donghoon Ahn, Ines Hyeonsu Kim +2

Score distillation sampling (SDS), the methodology in which the score from pretrained 2D diffusion models is distilled into 3D representation, has recently brought significant adva…

Self-Rectifying Diffusion Sampling with Perturbed-Attention Guidance

Donghoon Ahn, Hyoungwon Cho, Jaewon Min +6

Recent studies have demonstrated that diffusion models are capable of generating high-quality samples, but their quality heavily depends on sampling guidance techniques, such as cl…

Debiasing Scores and Prompts of 2D Diffusion for View-consistent Text-to-3D Generation

Susung Hong, Donghoon Ahn, Seungryong Kim

Existing score-distilling text-to-3D generation techniques, despite their considerable promise, often encounter the view inconsistency problem. One of the most notable issues is th…
