FL-MedSegBench overview: datasets, modalities, tasks and federated learning methods

Overview of FL-MedSegBench — a unified pipeline for evaluating global and personalized federated learning across diverse medical segmentation datasets, modalities and tasks.

Overview

FL-MedSegBench is a benchmark for federated learning (FL) in medical image segmentation. It provides a unified experimental framework to systematically evaluate both global FL (gFL) and personalized FL (pFL) methods across diverse medical imaging scenarios.

27+ datasets

Public medical segmentation datasets spanning brain, heart, prostate, pancreas, eye, gland, polyp and tissue-level targets.

10+ modalities

MRI, ultrasound, endoscopy, histology, fundus / retinal imaging, microscopy and other clinical modalities.

13+ methods

Representative gFL and pFL baselines, all trained and evaluated under one standardized, reproducible pipeline.
