Automated tibiofemoral joint segmentation based on deeply supervised 2D-3D ensemble U-Net: Data from the Osteoarthritis Initiative

作者:

Highlights:

• We presented a robust automatic tibiofemoral joint segmentation framework based on deeply supervised 2D-3D ensemble U-Net

• Foreground oversampling is performed to combat class imbalance - one-third of the patch contains at least one foreground class

• Deep supervision (weighted auxiliary loss) is considered a form of regularization to alleviate the gradient vanishing problem

• The end-to-end framework provides an exceptional segmentation speed leadership (~ 62 seconds) per 3D volume
