    摘要:

    针对遥感图像在跨模态检索任务中存在图像冗余信息干扰、多尺度信息提取不足、全局与局部信息无法有效融合导致的检索精度较低等问题,提出一种适用于多尺度任务的遥感图文检索模型IGMR。首先,设计多维感知增强卷积模块MFE,提取局部信息的同时过滤冗余特征,并通过融合多注意力模块来关注图像高频信息,提升特征表达能力。其次,设计多尺度分块注意力网络RFPA,捕获不同尺度的上下文信息。随后,构建自适应特征融合模块AFFM,将提取到的全局与局部特征进行动态融合,增强对高质量信息的关注。在公开数据集RSICD和RSITMD上的实验结果表明,提出的IGMR方法在遥感跨模态检索任务中,平均召回率mR分别提高了1.83%、3.21%,检索精度达到了19.73%和31.83%,总体检索性能显著提升。

    Abstract:

    Aiming at the issues of interference from redundant information in images, insufficient multi-scale information extraction, and low retrieval accuracy caused by the ineffective integration of global and local information in cross-modal retrieval tasks for remote sensing images, this paper proposes a network model of multi-scale cross-modal remote sensing image retrieval (IGMR) suitable for multi-scale tasks. Firstly, a multi-dimensional perception enhanced convolution module (MFE) is designed to extract local information while filtering redundant features. It also integrates a multi-attention module to focus on the high-frequency information of images, thereby enhancing feature expression ability. Secondly, a multi-scale patch attention network (RFPA) is developed to capture contextual information at different scales. Subsequently, an adaptive feature fusion module (AFFM) is constructed to dynamically fuse the extracted global and local features, strengthening attention to high-quality information. Experimental results on the public datasets RSICD and RSITMD demonstrate that the proposed IGMR method increases the average recall rate (mR) by 1.83% and 3.21% respectively in remote sensing cross-modal retrieval tasks, with retrieval accuracies reaching 19.73% and 31.83%. The overall retrieval performance is significantly improved.
