An Exceptional Dataset For Rare Pancreatic Tumor Segmentation

ICASSP 2025accepted

Pancreatic NEuroendocrine Tumors (pNETs) are very rare endocrine neoplasms that account for less than 5% of all pancreatic malignancies, with an incidence of only 1–1.5 cases per 100,000. Early detection of pNETs is critical for improving patient survival, but the rarity of pNETs makes segmenting th…

DPSN: Dual Prior Knowledge Induced Tactile paving and Obstacle Joint Segmentation Network

IROS 2025

Accurate semantic segmentation of both tactile paving and the obstacle is crucial for the safe mobility of visually impaired individuals. However, existing methods face two major challenges: (i) discontinuous segmentation fragments; (ii) Inaccurate obstacle recognition. To address challenge (i), we

VILA-M3: Enhancing Vision-Language Models with Medical Expert Knowledge

CVPR 2025highlight

Generalist vision language models (VLMs) have made significant strides in computer vision, but they fall short in specialized fields like healthcare, where expert knowledge is essential. Current large multimodal models like Gemini and GPT-4o are insufficient for medical tasks due to their reliance o…

Communication-Efficient Vertical Federated Learning with Limited Overlapping Samples

ICCV 2023poster

Federated learning is a popular collaborative learning approach that enables clients to train a global model without sharing their local data. Vertical federated learning (VFL) deals with scenarios in which the data on clients have different feature spaces but share some overlapping samples. Existin…

Fair Federated Medical Image Segmentation via Client Contribution Estimation

CVPR 2023poster

How to ensure fairness is an important topic in federated learning (FL). Recent studies have investigated how to reward clients based on their contribution (collaboration fairness), and how to achieve uniformity of performance across clients (performance fairness). Despite achieving progress on eith…

Auto-FedRL: Federated Hyperparameter Optimization for Multi-Institutional Medical Image Segmentation

ECCV 2022poster

"Federated learning (FL) is a distributed machine learning technique that enables collaborative model training while avoiding explicit data sharing. The inherent privacy-preserving property of FL algorithms makes them especially attractive to the medical field. However, in case of heterogeneous clie…

GradViT: Gradient Inversion of Vision Transformers

CVPR 2022poster

In this work we demonstrate the vulnerability of vision transformers (ViTs) to gradient-based inversion attacks. During this attack, the original data batch is reconstructed given model weights and the corresponding gradients. We introduce a method, named GradViT, that optimizes random noise into na…
