Abstract:

The current synthetic aperture radar (SAR) ship instance segmentation models fail to realize mask interaction or the interaction performance is limited, resulting in low detection accuracy. To solve this problem, a SAR ship instance segmentation method based on mask attention interaction (MAI) is proposed, called MAI-Net. Firstly, MAI-Net uses the atrous spatial pyramid pooling (ASPP) to obtain multi-resolution feature responses and enhance the background identification capability. Secondly, MAI-Net uses a non-local block (NLB) to suppress useless information and realize spatial feature self-attention. Finally, MAI-Net proposes the concatenation shuffle attention block (CSAB), which can balance the contribution of different features and further improve the instance segmentation accuracy. The results on the public polygon segmentation SAR ship detection dataset (PSeg-SSDD) show that the SAR ship instance segmentation accuracy of MAI-Net is higher than that of the other eleven comparison models, the accuracy is 61.1%, 1.5% higher than the suboptimal model.

Key words: synthetic aperture radar (SAR), deep learning, instance segmentation, mask attention interaction
