An Empirical Study of Federated Prompt Learning for Vision Language Model

IJCAI 2025

The Vision Language Model (VLM) excels in aligning vision and language representations, and prompt learning has emerged as a key technique for adapting such models to downstream tasks. However, the application of prompt learning with VLM in federated learning (FL) scenarios remains underexplored. Th

Pixel-wise Divide and Conquer for Federated Vessel Segmentation

IJCAI 2025

Accurate vessel segmentation is essential for diagnosing and managing vascular and ophthalmic diseases. Traditional learning-based vessel segmentation methods heavily rely on high-quality, pixel-level annotated datasets. However, segmentation performance suffers significantly when applied in federat

Enhancing the Transferability of Adversarial Examples with Random Patch

IJCAI 2022poster

Adversarial examples can fool deep learning models, and their transferability is critical for attacking black-box models in real-world scenarios. Existing state-of-the-art transferable adversarial attacks tend to exploit intrinsic features of objects to generate adversarial examples. This paper prop…

Camera-Space Hand Mesh Recovery via Semantic Aggregation and Adaptive 2D-1D Registration

CVPR 2021poster

Recent years have witnessed significant progress in 3D hand mesh recovery. Nevertheless, because of the intrinsic 2D-to-3D ambiguity, recovering camera-space 3D information from a single RGB image remains challenging. To tackle this problem, we divide camera-space mesh recovery into two sub-tasks, i…

Improving Monocular Depth Estimation by Leveraging Structural Awareness and Complementary Datasets

ECCV 2020poster

Monocular depth estimation plays a crucial role in 3D recognition and understanding. One key limitation of existing approaches lies in their lack of structural information exploitation, which leads to inaccurate spatial layout, discontinuous surface, and ambiguous boundaries. In this paper, we tackl…
