Improved-Mask R-CNN: Towards an Accurate Generic MSK MRI instance segmentation platform (Data from the Osteoarthritis Initiative). (arXiv:2107.12889v2 [eess.IV] UPDATED)

Objective assessment of Magnetic Resonance Imaging (MRI) scans of
osteoarthritis (OA) can address the limitation of the current OA assessment.
Segmentation of bone, cartilage, and joint fluid is necessary for the OA
objective assessment. Most of the proposed segmentation methods are not
performing instance segmentation and suffer from class imbalance problems. This
study deployed Mask R-CNN instance segmentation and improved it (improved-Mask
R-CNN (iMaskRCNN)) to obtain a more accurate generalized segmentation for
OA-associated tissues. Training and validation of the method …
