ABCNet: Attentive Bilateral Contextual Network for Efficient Semantic Segmentation of Fine-Resolution Remote Sensing Images

⭐ Welcome to my HomePage ⭐

In this repository, we implement the Attentive Bilateral Contextual Network which contains a spatial path and a contextual path to fully capture the long-range relationships and fine-grained details in fine-resolution remote sensing images.

The detailed results can be seen in the ABCNet: Attentive Bilateral Contextual Network for Efficient Semantic Segmentation of Fine-Resolution Remote Sensing Images.

The training and testing code can refer to GeoSeg.

• MACU-Net->A modified version of U-Net.
• BANet->A Transformer-based segmentation network.
• MAResU-Net->A ResNet-based network with attention mechanism.
• Multi-Attention-Network->A network with multi kernel attention mechanism.
