Figure 2

The architecture of U-Net. The network consists of two parts. The left half is feature extraction. After each pool layer, the scale of feature changes. There are five scales in total. The right half is upsampling. Every time the feature is upsampled, it will be fused with the same scale corresponding to the feature extraction part.
