摘要

随着遥感技术的飞速发展和遥感图像的广泛应用,遥感物体检测已成为一个热门研究方向。然而,我们发现遥感物体检测面临三个主要挑战:尺度变化、小物体和复杂背景。针对这些挑战,我们提出了一种新型检测器--多尺度情境感知网络(MSCANet)。首先,我们引入了多尺度融合模块(MSFM),该模块提供各种尺度的感受野,以充分提取不同尺度物体的上下文信息。其次,我们提出了多尺度引导模块(MSGM),它融合了多个尺度的深层和浅层特征图,减少了小物体特征信息的损失。最后,我们引入了上下文感知下采样模块(CADM)。它能动态调整不同尺度的上下文信息权重,有效减少复杂背景的干扰。实验结果表明,所提出的 MSCANet 在具有挑战性的 RSOD 和 DIOR 数据集上取得了优异的性能结果,平均精度(mAP)分别达到 97.1% 和 73.4%,这表明所提出的网络适用于遥感物体检测,具有很高的参考价值。

MSCANet: A multi-scale context-aware network for remote sensing object detection

With the rapid development of remote sensing technology and the widespread application of remote sensing images, remote sensing object detection has become a hot research direction. However, we observe three primary challenges in remote sensing object detection: scale variations, small objects, and complex backgrounds. To address these challenges, we propose a novel detector, he Multi-Scale Context-Aware Network (MSCANet). First, we introduce a Multi-Scale Fusion Module (MSFM) that provides various scales of receptive fields to extract contextual information of objects at different scales adequately. Second, the Multi-Scale Guidance Module (MSGM) is proposed, which fuses deep and shallow feature maps from multiple scales, reducing the loss of feature information in small objects. Finally, we introduce the Context-Aware DownSampling Module (CADM). It dynamically adjusts context information weights at different scales, effectively reducing interference from complex backgrounds. Experimental results demonstrate that the proposed MSCANet achieves superior performance results with mean average precision (mAP) of 97.1% and 73.4% on the challenging RSOD and DIOR datasets, respectively, which indicates that the proposed network is suitable for remote sensing object detection and is of a great reference value.

期刊介绍: The Earth Science Informatics [ESIN] journal aims at rapid publication of high-quality, current, cutting-edge, and provocative scientific work in the area of Earth Science Informatics as it relates to Earth systems science and space science. This includes articles on the application of formal and computational methods, computational Earth science, spatial and temporal analyses, and all aspects of computer applications to the acquisition, storage, processing, interchange, and visualization of data and information about the materials, properties, processes, features, and phenomena that occur at all scales and locations in the Earth system’s five components (atmosphere, hydrosphere, geosphere, biosphere, cryosphere) and in space (see "About this journal" for more detail). The quarterly journal publishes research, methodology, and software articles, as well as editorials, comments, and book and software reviews. Review articles of relevant findings, topics, and methodologies are also considered.
