DepthLM: Metric Depth from Vision Language Models

ICLR 2026oral

Vision language models (VLMs) can flexibly address various vision tasks through text interactions. Although successful in semantic understanding, state-of-the-art VLMs including GPT-5 still struggle in understanding 3D from 2D inputs. On the other hand, expert pure vision models achieve super-human…

EgoAVU: Egocentric Audio-Visual Understanding

CVPR 2026

Understanding egocentric videos plays a vital role for embodied intelligence. Recent multi-modal large language models (MLLMs) can accept both visual and audio inputs. However, due to the challenge of obtaining text labels with coherent joint-modality information, whether MLLMs can jointly understan

Cohere3D: Exploiting Temporal Coherence for Unsupervised Representation Learning of Vision-Based Autonomous Driving

ICRA 2025

Multi-frame temporal inputs are important for vision-based autonomous driving. Observations from different angles enable the recovery of 3 D object states from 2 D images as long as we can identify the same instance from different input frames. However, the dynamic nature of driving scenes leads to

Flash3D: Super-scaling Point Transformers through Joint Hardware-Geometry Locality

CVPR 2025highlight

Recent efforts recognize the power of scale in 3D learning (e.g. PTv3) and attention mechanisms (e.g. FlashAttention).However, current point cloud backbones fail to holistically unify geometric locality, attention mechanisms, and GPU architectures in one view.In this paper, we introduce Flash3D Tran…

Generative Data Mining with Longtail-Guided Diffusion

ICML 2025poster

It is difficult to anticipate the myriad challenges that a predictive model will encounter once deployed. Common practice entails a reactive, cyclical approach: model deployment, data mining, and retraining. We instead develop a proactive longtail discovery process by imagining additional data durin…

VLM-AD: End-to-End Autonomous Driving through Vision-Language Model Supervision

CoRL 2025poster

Human drivers rely on commonsense reasoning to navigate diverse and dynamic real-world scenarios. Existing end-to-end (E2E) autonomous driving (AD) models are typically optimized to mimic driving patterns observed in data, without capturing the underlying reasoning processes. This limitation constr…

ViP-LLaVA: Making Large Multimodal Models Understand Arbitrary Visual Prompts

CVPR 2024poster

While existing large vision-language multimodal models focus on whole image understanding there is a prominent gap in achieving region-specific comprehension. Current approaches that use textual coordinates or spatial encodings often fail to provide a user-friendly interface for visual prompting. To…
