The Improvement of Automated Crack Segmentation on Concrete Pavement with Graph Network

Figure 5

The structure of the whole network. The top-line describes the processing of the image in the U-Net. The number above the feature map presents the number of channels. The number beside the feature presents the size of the feature map. The following line describes the processing in the graph neural network branch. And the feature map in the U-Net and the graph network branch are fused after the first decoding.
