Abstract: Highlights•Global Context Feature Extraction (GCFE) module is proposed, which can extract multi-scale global contextual information.•A Dual Scale Feature Aggregation (DSFA) module is proposed to fuse the features from different scales.•A learnable Gabor convolution layer is designed to enhance its ability to capture the edge and contour information of object.•A Spatial Attention (SA) mechanism is designed to further enhance the spatial structure information of object.
