FIRM: Fine-Grained Intra-Token Representation of Masks for Remote Sensing Reasoning Segmentation

Aug 14, 2026

This study addresses the issues of coarse boundaries and instance adhesion in remote sensing semantic segmentation caused by multi-target mixing within visual tokens. To overcome these limitations, we propose FIRM, a novel method that innovatively introduces intra-token sub-unit mask representations and a lightweight continuous rendering mechanism. By transcending single-label constraints through sub-unit prediction, lookup table transformation, and soft structural field marginalization, FIRM achieves fine-grained segmentation. Extensive experiments demonstrate state-of-the-art performance across five benchmarks. Notably, on the LASER dataset, FIRM attains GIoU/CIoU scores of 70.5/80.5 and improves the EarthReason metric by 3.0 points, significantly enhancing segmentation accuracy in complex scenes.
