摘要:

近年来,在海量数据集上训练的大型基础模型在特征提取和通用特征表示方面展现出了卓越的能力。深度学习驱动的大型模型的持续进步,在加速无监督变化检测方法方面显示出巨大潜力,从而增强了变化检测技术的实际应用性。在此进展基础上,本文提出了MergeSAM,一种基于Segment Anything Model(SAM)的高分辨率遥感影像创新无监督变化检测方法。设计了两种新颖的策略,即MaskMatching和MaskSplitting,以应对物体分裂、合并及其他复杂变化等现实复杂性。所提出的方法充分利用了SAM的物体分割能力来构建捕获复杂变化的多时相掩码,将土地覆盖的空间结构嵌入到变化检测过程中。

英文摘要:

Recently, large foundation models trained on vast datasets have demonstrated exceptional capabilities in feature extraction and general feature representation. The ongoing advancements in deep learning-driven large models have shown great promise in accelerating unsupervised change detection methods, thereby enhancing the practical applicability of change detection technologies. Building on this progress, this paper introduces MergeSAM, an innovative unsupervised change detection method for high-resolution remote sensing imagery, based on the Segment Anything Model (SAM). Two novel strategies, MaskMatching and MaskSplitting, are designed to address real-world complexities such as object splitting, merging, and other intricate changes. The proposed method fully leverages SAM's object segmentation capabilities to construct multitemporal masks that capture complex changes, embedding the spatial structure of land cover into the change detection process.
