摘要: 目标检测在自然场景和遥感场景中的研究极具挑战。尽管许多先进的算法在自然场景下取得了优异的成果,但是遥感图像的复杂性、目标尺度的多样性及目标密集分布的特性,使得针对遥感图像目标检测的研究步伐缓慢。本文提出一个新颖的多类别目标检测模型,可以自动学习特征融合时的权重,并突出目标特征,实现在复杂的遥感图像中有效地检测小目标和密集分布的目标。模型在公开数据集DOTA和NWPU VHR-10上的实验结果表明检测效果超过了大多数经典算法。

Abstract: The research of object detection in natural scenes and remote sensing scenes is extremely challenging. Although many advanced algorithms have achieved excellent results in natural scenes, the complexity of remote sensing images, the diversity of object scales, and the dense distribution of object make the research on remote sensing image object detection slow. This paper proposes a novel multi-category object detection model which can automatically learn the weights of feature fusion and highlight object features at the same time. As a result, the model achieves effective detection of small objects and densely distributed objects in complex remote sensing images. The experimental results of the model on public datasets DOTA and NWPU VHR-10 show that the detection effect exceeds that of most classical algorithms.
