基于Transformer的遥感图像变化检测研究进展

    Research Progress of Transformer-based Remote Sensing Image Change Detection

    • 摘要: 光照、季节、气候、太阳高度和角度变化等因素的影响,以及目标区域的散乱性和尺度多变性,使得遥感图像变化检测领域面临着巨大的技术挑战。近年来,Transformer在自然语言处理、目标检测、图像分割等领域取得成功,成为遥感图像变化检测的研究热点。因此,综述了基于Transformer的最新研究进展,分析了基于纯Transformer和基于卷积神经网络(convolutional neural network,CNN)+Transformer混合架构的2类方法,对它们在多种遥感图像公共数据集上的性能进行了比较,总结了不同方法的优缺点,并展望了未来可能的发展趋势。

       

      Abstract: Due to complex factors, including illumination, seasons, phenology, solar height and angle changes, as well as the scattered and diverse nature of the target areas to be detected, along with the variability in scale and direction, remote sensing image change detection enfaces great technical challenges. In recent years, Transformer has demonstrated remarkable success in various fields such as natural language processing, object detection, and image segmentation, becoming a research focus. This paper reviews the latest research progress of Transformer-based remote sensing image change detection, and analyzes two types of methods based on pure transformer and convolutional neural Network (CNN) + Transformer. Then, a comparative analysis of the detection performance of different methods on public datasets is conducted, highliting the respective merits and limitations of various methods. Finally, future possible development trends are discussed.
