本文提出DC-Mamba框架,通过双时相可变形对齐与尺度稀疏变化放大两个轻量模块,在ChangeMamba基线上显著提升遥感变化检测的F1和IoU,有效抑制伪变化并增强细微目标。

摘要:

遥感变化检测(RSCD)对于识别土地覆盖变化至关重要,然而现有方法,包括最先进的State Space Models(SSMs),通常缺乏处理几何失配的显式机制,并且难以区分细微的真实变化与噪声。为了解决这一问题,我们提出了DC-Mamba,一个基于ChangeMamba骨干网络构建的“先对齐后增强”框架。该框架集成了两个轻量级、即插即用的模块:(1)Bi-Temporal Deformable Alignment(BTDA),在语义特征层面显式引入几何感知以校正空间失配;(2)Scale-Sparse Change Amplifier(SSCA),利用多源线索在最终分类前选择性地放大高置信度变化信号,同时抑制噪声。这种协同设计首先通过BTDA建立几何一致性以减少伪变化,然后利用SSCA锐化边界并增强细小或微弱目标的可视性。实验表明,我们的方法在强大的ChangeMamba基线上显著提升了性能,F1-score从0.5730提高到0.5903,IoU从0.4015提高到0.4187。结果证实了“先对齐后增强”策略的有效性,为RSCD中几何层面和特征层面的挑战提供了一种鲁棒且易于部署的解决方案。

英文摘要:

Remote sensing change detection (RSCD) is vital for identifying land-cover changes, yet existing methods, including state-of-the-art State Space Models (SSMs), often lack explicit mechanisms to handle geometric misalignments and struggle to distinguish subtle, true changes from noise.To address this, we introduce DC-Mamba, an "align-then-enhance" framework built upon the ChangeMamba backbone. It integrates two lightweight, plug-and-play modules: (1) Bi-Temporal Deformable Alignment (BTDA), which explicitly introduces geometric awareness to correct spatial misalignments at the semantic feature level; and (2) a Scale-Sparse Change Amplifier(SSCA), which uses multi-source cues to selectively amplify high-confidence change signals while suppressing noise before the final classification. This synergistic design first establishes geometric consistency with BTDA to reduce pseudo-changes, then leverages SSCA to sharpen boundaries and enhance the visibility of small or subtle targets. Experiments show our method significantly improves performance over the strong ChangeMamba baseline, increasing the F1-score from 0.5730 to 0.5903 and IoU from 0.4015 to 0.4187. The results confirm the effectiveness of our "align-then-enhance" strategy, offering a robust and easily deployable solution that transparently addresses both geometric and feature-level challenges in RSCD.
