Figure 7

Dice coefficient of U-Net and DenseU-Net on the training set curve with the number of iterations. The U-Net has a Dice coefficient of 0.978 in the training set and a Dice coefficient of 0.945 in the validation set. The Dice coefficient of DenseU-Net is 0.987 in the training set and 0.955 in the validation set.
