DynamicCity: Large-Scale 4D Occupancy Generation from Dynamic Scenes

ICLR 2025spotlight

Urban scene generation has been developing rapidly recently. However, existing methods primarily focus on generating static and single-frame scenes, overlooking the inherently dynamic nature of real-world driving environments. In this work, we introduce DynamicCity, a novel 4D occupancy generation f…

Bridging the Gap: A Unified Video Comprehension Framework for Moment Retrieval and Highlight Detection

CVPR 2024poster

Video Moment Retrieval (MR) and Highlight Detection (HD) have attracted significant attention due to the growing demand for video analysis. Recent approaches treat MR and HD as similar video grounding problems and address them together with transformer-based architecture. However we observe that the…

Metric from Human: Zero-shot Monocular Metric Depth Estimation via Test-time Adaptation

NeurIPS 2024poster

Monocular depth estimation (MDE) is fundamental for deriving 3D scene structures from 2D images. While state-of-the-art monocular relative depth estimation (MRDE) excels in estimating relative depths for in-the-wild images, current monocular metric depth estimation (MMDE) approaches still face chall…
