Abstract:

To address the issues of high sample dependence and poor multi-temporal data fusion effectiveness in multi-source image ship target detection, this paper proposes an adaptive decision fusion method based on D-S (Dempster-Shafer) evidence theory. Departing from the traditional fuse-then-detect framework, this method constructs a differentiated basic probability assignment model. It transforms the information interference generated by fusing samples from different time periods into complementary benefits, effectively overcoming the dependence on simultaneous-phase samples in multi-source fusion detection and achieving effective decision fusion of multi-source images. Experimental results show that the proposed method improves average precision (AP) by 0.7% and 2.92% respectively compared to single-source optical and synthetic aperture radar (SAR) image detection. Compared with conventional fusion detection algorithms, it reduces computational overhead while significantly enhancing detection accuracy.
