Enhancing Consistency of Flow-Based Image Editing through Kalman Control

NeurIPS 2025poster

Flow-based generative models have gained popularity for image generation and editing. For instruction-based image editing, it is critical to ensure that modifications are confined to the targeted regions. Yet existing methods often fail to maintain consistency in non-targeted regions between the ori…

MovieChat: From Dense Token to Sparse Memory for Long Video Understanding

CVPR 2024poster

Recently integrating video foundation models and large language models to build a video understanding system can overcome the limitations of specific pre-defined vision tasks. Yet existing systems can only handle videos with very few frames. For long videos the computation complexity memory cost and…

RectifID: Personalizing Rectified Flow with Anchored Classifier Guidance

NeurIPS 2024poster

Customizing diffusion models to generate identity-preserving images from user-provided reference images is an intriguing new problem. The prevalent approaches typically require training on extensive domain-specific images to achieve identity preservation, which lacks flexibility across different use…
