Change-LISA: Language-Guided Reasoning for Remote Sensing Change Detection (opens in new tab)

Remote sensing change detection (RSCD) is widely used for monitoring land-surface dynamics. Most models, however, output an unconditional ”all-changes” map and do not account for user intents expressed in natural language. This can lead to spurious masks under counterfactual (i.e., negative/mismatched) queries. This article studies language-guided reasoning change detection. Given a bitemporal image pair and a text instruction, the model outputs an instruction-conditioned change mask; the cor...
