Chaowei Tan, Zhennan Yan, Shaoting Zhang, Kang Li, Dimitris N. Metaxas
2019 arXiv   pre-print
In this paper, we propose a novel framework to solve the MR knee cartilage segmentation task. The key contribution is the adversarial learning based collaborative multi-agent segmentation network.  ...  The 3D morphology and quantitative assessment of knee articular cartilages (i.e., femoral, tibial, and patellar cartilage) in magnetic resonance (MR) imaging is of great importance for knee radiographic  ...  In this paper, we propose a novel segmentation framework with collaborative multi-agent learning (shown in Fig. 2 ) for the task of knee cartilage labeling in large-sized and high-resolution 3D MR data  ...
