An Automatic LiDAR-Camera Extrinsic Calibration Method for Sparse Point Clouds Using Boundary Features

ICRA 2026poster

Extrinsic calibration for LiDAR and camera using sparse point clouds can significantly reduce cost and improve efficiency. However, most target-based methods are designed for dense point clouds and are less effective in sparse scenarios, while targetless methods primarily rely on environmental featu…

UniME-V2: MLLM-as-a-Judge for Universal Multimodal Embedding Learning

AAAI 2026technical

Universal multimodal embedding models are essential in various tasks. Existing approaches typically use in-batch mining to identify hard negatives by measuring the similarity of query-candidate pairs. However, these methods often struggle to capture subtle semantic differences among candidates and l

CLIP-CID: Efficient CLIP Distillation via Cluster-Instance Discrimination

AAAI 2025technical

Contrastive Language-Image Pre-training (CLIP) has achieved excellent performance over a wide range of tasks. However, the effectiveness of CLIP heavily relies on a substantial corpus of pre-training data, resulting in notable consumption of computational resources. Although knowledge distillation h…

RWKV-CLIP: A Robust Vision-Language Representation Learner

EMNLP 2024main

Contrastive Language-Image Pre-training (CLIP) has significantly improved performance in various vision-language tasks by expanding the dataset with image-text pairs obtained from the web. This paper further explores CLIP from the perspectives of data and model architecture. To mitigate the impact o…
