SketchThinker-R1: Towards Efficient Sketch-Style Reasoning in Large Multimodal Models

ICLR 2026poster

Despite the empirical success of extensive, step-by-step reasoning in large multimodal models, long reasoning processes inevitably incur substantial computational overhead, i.e., in terms of higher token costs and increased response time, which undermines inference efficiency. In contrast, humans of…

TIGeR: Text-Instructed Generation and Refinement for Template-Free Hand-Object Interaction

ICRA 2026poster

Pre-defined 3D object templates are widely used in 3D reconstruction of hand-object interactions. However, they often require substantial manual efforts to capture or source, and inherently restrict the adaptability of models to unconstrained interaction scenarios, e.g., heavily-occluded objects. To…

The Coherence Trap: When MLLM-Crafted Narratives Exploit Manipulated Visual Contexts

CVPR 2026

The detection and grounding of multimedia manipulation has emerged as a critical challenge in combating AI-generated disinformation. While existing methods have made progress in recent years, we identify two fundamental limitations in current approaches: (1) Underestimation of MLLM-driven deception

Coarse-to-Fine Cross-Modality Generation for Enhancing Vehicle Re-Identification with High-Fidelity Synthetic Data

ICRA 2025

Due to the critical issues of privacy and partial occlusion, license plate information is not always available in vehicle recognition systems. Consequently, researchers have increasingly turned towards vehicle re-identification (reID) techniques to bridge the gap between cross-view camera systems. D

Harnessing Uncertainty-aware Bounding Boxes for Unsupervised 3D Object Detection

ICCV 2025poster

Unsupervised 3D object detection aims to identify objects of interest from unlabeled raw data, such as LiDAR points. Recent approaches usually adopt pseudo 3D bounding boxes (3D bboxes) from clustering algorithm to initialize the model training. However, pseudo bboxes inevitably contain noise, and s…

Video2BEV: Transforming Drone Videos to BEVs for Video-based Geo-localization

ICCV 2025poster

Existing approaches to drone visual geo-localization predominantly adopt the image-based setting, where a single drone-view snapshot is matched with images from other platforms. Such task formulation, however, underutilizes the inherent video output of the drone and is sensitive to occlusions and vi…

VimoRAG: Video-based Retrieval-augmented 3D Motion Generation for Motion Language Models

NeurIPS 2025poster

This paper introduces **VimoRAG**, a novel video-based retrieval-augmented motion generation framework for motion large language models (LLMs). As motion LLMs face severe out-of-domain/out-of-vocabulary issues due to limited annotated data, **VimoRAG** leverages large-scale in-the-wild video databa…

Composed Image Retrieval with Text Feedback via Multi-grained Uncertainty Regularization

ICLR 2024poster

We investigate composed image retrieval with text feedback. Users gradually look for the target of interest by moving from coarse to fine-grained feedback. However, existing methods merely focus on the latter, i.e., fine-grained search, by harnessing positive and negative pairs during training. Thi…

Multi-View Consistent Generative Adversarial Networks for 3D-Aware Image Synthesis

CVPR 2022poster

3D-aware image synthesis aims to generate images of objects from multiple views by learning a 3D representation. However, one key challenge remains: existing approaches lack geometry constraints, hence usually fail to generate multi-view consistent images. To address this challenge, we propose Multi…
