Improving Motion in Image-to-Video Models via Adaptive Low-Pass Guidance

CVPR 2026

Recent text-to-video (T2V) models have demonstrated strong capabilities in producing high-quality, dynamic videos. To improve the visual controllability, recent works have considered fine-tuning pre-trained T2V models to support image-to-video (I2V) generation. However, such adaptation frequently su

Silent Branding Attack: Trigger-free Data Poisoning Attack on Text-to-Image Diffusion Models

CVPR 2025poster

Text-to-image diffusion models have achieved remarkable success in generating high-quality contents from text prompts. However, their reliance on publicly available data and the growing trend of data sharing for fine-tuning make these models particularly vulnerable to data poisoning attacks. In this…

Collaborative Score Distillation for Consistent Visual Editing

NeurIPS 2023poster

Generative priors of large-scale text-to-image diffusion models enable a wide range of new generation and editing applications on diverse visual modalities. However, when adapting these priors to complex visual modalities, often represented as multiple images (e.g., video or 3D scene), achieving con…
