The network structure of traditional ResNet-18-based classification model (without the relative distance-from-edge mechanism). The location-attention classification model was built on the backbone of ResNet-18 by concatenating the location-attention mechanism in the full-connection layer to improve the overall accuracy rate. Conv2D: convolution 2D.
