Abstract:

In order to solve the problem of low quality of multimodal ship image fusion recognition, an end-to-end low rank bilinear pooling attention network is constructed. Firstly, the original feature vector of each modal are reconstructed based on the cross-modal category center, so that different modal features can pay more attention to the common category information. Then, bilinear pooling is used to capture the interactive information of different modal images, and the weight low rank decomposition is introduced to reduce the scale of network parameters. Finally, the interaction and complementarity of modal information are realized by feature cascaded, and the joint loss is designed to improve the effect of network cross-modal fusion recognition. The experimental results show that compared with the existing fusion methods, the proposed method can effectively improve the fusion recognition effect of multimodal remote sensing ship images, and achieve high recognition accuracy on the public remote sensing ship datasets.

Key words: ship recognition, bilinear pooling, cross-modal category center, attention weighting, cross-modal joint loss
