A Deep Learning Segmentation Approach in Free-Breathing Real-Time Cardiac Magnetic Resonance Imaging

Figure 6

Comparison of the learning curves of proposed network and U-Net with cross-entropy (CE) loss, improved generalized Dice (IGD) loss, and data augmentation (DA). Dice curve (a, c) and loss curve (b, d) of training and validation sets, respectively. Note that the learning curves have been smoothed by moving average method.
