CaMiT: A Time-Aware Car Model Dataset for Classification and Generation

NeurIPS 2025poster

AI systems must adapt to the evolving visual landscape, especially in domains where object appearance shifts over time. While prior work on time-aware vision models has primarily addressed commonsense-level categories, we introduce Car Models in Time (CaMiT). This fine-grained dataset captures the t…

Cross-Modal Distillation for 2D/3D Multi-Object Discovery from 2D Motion

CVPR 2025poster

Object discovery, which refers to the task of localizing objects without human annotations, has gained significant attention in 2D image analysis. However, despite this growing interest, it remains under-explored in 3D data, where approaches rely exclusively on 3D motion, despite its several challen…

DIOD: Self-Distillation Meets Object Discovery

CVPR 2024poster

Instance segmentation demands substantial labeling resources. This has prompted increased interest to explore the object discovery task as an unsupervised alternative. In particular promising results were achieved in localizing instances using motion supervision only. However the motion signal intro…
