[0018] Technical terms:
[0019] Atrous Transformation Feature Pyramid Module (AT-FPM);
[0020] Stage Feature Attention Module (StageFeatureAttention, SF-Attention);
[0021] Feature Pyramid Module (Feature PyramidModule, FPM);
[0022] Atrous Spatial Pyramid Pooling.
[0023] The design concept of the present invention is to propose a soft weighted multi-stage feature network composed of an atrous transform feature pyramid module (AT-FPM) and a stage feature attention module (SF-Attention). In AT-FPM, a concept of adopting different transformation functions for different stage features is proposed. Specifically, for deep stage features, the adaptive feature transformation function of the feature pyramid module is replaced by hollow space pyramid pooling, which expands the overall receptive field of the network and better extracts the features and global information of large-scale targets; while for the shallow layer features, the adaptive transformation function is used ...
