    面向遥感图像场景分类的特征对比域适应网络

    Feature Contrast Domain Adaptation Network for Remote Sensing Image Scene Classification

    • 摘要: 遥感图像场景分类能够提供实时的地表信息,对于复杂环境态势感知具有重要意义。遥感图像训练和测试数据通常来自不同分布,导致算法模型泛化性能差。针对场景分类任务中目标域与源域数据存在差异的问题,提出一种特征对比域适应网络,提取遥感图像域风格特征,构建域对比特征转换方法,实现遥感图像跨域场景分类。所提方法在公开遥感数据集上开展实验, 较国际同类方法具有更优的性能。

       

      Abstract: Remote sensing image scene classification plays a crucial role in providing real-time surface information, particularly for complex environmental situational awareness. However, the discrepancy between taining and testing data in remote sensing images often leads to poor generalization performance of the models. To address the issue of differences between the target domain and the sowrce domain in scene classification tasks, this paper proposes a feature contrast domain adaptation network, which facilitates remote sensing image cross-domain scene classification. This network can extract the domain-specific style features for remote sensing images and construct the domain contrast features transformation method to achieve cross-domain scene classification of remote sensing images. Experimental evaluations conducted on publicly available remote sensing datasets demonstrate that the proposed method outperforms the other domain adaptation methods.
