Like Human Rethinking: Contour Transformer AutoRegression for Referring Remote Sensing Interpretation

Le résumé fourni par la source

Referring remote sensing interpretation holds significant application value in various scenarios such as ecological protection, resource exploration, and emergency management. However, referring remote sensing expression comprehension and segmentation (RRSECS) faces critical challenges, including micro-target localization drift problem caused by insufficient extraction of boundary features in existing paradigms. Moreover, when transferred to remote sensing domains, polygon-based methods encounter issues such as contour-boundary misalignment and multi-task co-optimization conflicts problems. In this paper, we propose SeeFormer, a novel contour autoregressive paradigm specifically designed for RRSECS, which accurately locates and segments micro, irregular targets in remote sensing imagery. We first introduce a brain-inspired feature refocus learning (BIFRL) module that progressively attends to effective object features via a coarse-to-fine scheme, significantly boosting small-object localization and segmentation. Next, we present a language-contour enhancer (LCE) that injects shape-aware contour priors, and a corner-based contour sampler (CBCS) to improve mask-polygon reconstruction fidelity. Finally, we develop an autoregressive dual-decoder paradigm (ARDDP) that preserves sequence consistency while alleviating multi-task optimization conflicts. Extensive experiments on RefDIOR, RRSISD, and OPTRSVG datasets under varying scenarios, scales, and task paradigms demonstrate transformative performance gains: compared to the baseline PolyFormer, our proposed SeeFormer improves oIoU and mIoU by 27.58% and 39.37% for referring image segmentation and by 18.94% and 28.90% for visual grounding on the RefDIOR dataset.
