    This study introduces a novel bidirectional spatial-adaptive network (BSANet) for weakly-supervised object detection in remote sensing images. BSANet effectively addresses challenges with small or rare objects, improving detection accuracy.

    Area of Science:

    • Computer Science
    • Remote Sensing
    • Artificial Intelligence

    Background:

    • Weakly-supervised object detection (WSOD) methods in remote sensing images (RSIs) struggle with small-scale instances, rare poses, and crowded scenes.
    • Current WSOD approaches often overlook valuable candidate proposals by focusing solely on top-scoring regions.

    Purpose of the Study:

    • To develop an advanced WSOD network for RSIs that mitigates challenges posed by scale, pose variations, and crowded scenes.
    • To improve the excavation of entire instances and enhance feature learning by addressing limitations of existing methods.

    Main Methods:

    • Proposes a data-driven bidirectional spatial-adaptive network (BSANet) incorporating a forward-reverse spatial dropout (FRSD) module.
    • The FRSD module acts as a data-driven hard attention mechanism, adaptively sampling and reconstructing spatial regions to uncover latent features.

  • Introduces a soft attention branch to model both pixel-level and region-level attention, leveraging complementary benefits.

    • Main Results:

    • The proposed BSANet effectively reduces instance ambiguity caused by extreme scales, poses, and crowded scenes.
    • Experimental results on NWPU VHR-10.v2 and DIOR datasets demonstrate significant improvements in detection performance.
    • The method achieves new state-of-the-art results on challenging remote sensing object detection benchmarks.

    Conclusions:

    • The BSANet offers a robust solution for weakly-supervised object detection in remote sensing images.
    • The integration of bidirectional spatial adaptation and combined soft/hard attention mechanisms enhances the ability to detect challenging objects.
    • This work advances the field of WSOD in remote sensing by setting a new performance benchmark.
