Evidencepartial
We report per-group IoU (%), mean IoU (mIoU↑), and average accuracy (aAcc↑).
Implicationpartial
Directly supported by experimental results table (Table I) showing mIoU values, with the method's performance being reported as best or second best.
Verificationpartial
partial
Evidencepartial
First, a global–local token refinement module consolidates semantic context on a compact bottleneck lattice, guided by boundary-aware regularization to remain robust under ambiguous supervision.
Implicationpartial
Explicitly stated as a core component of the method in the abstract and methodology section.
Verificationpartial
partial
Evidencepartial
Second, a gated detail bridge selectively injects fine-scale structural cues only once through cross-scale attention, preserving boundary and texture information while avoiding noise accumulation.
Implicationpartial
Explicitly stated as a core component of the method in the abstract and methodology section.
Verificationpartial
partial
Evidencepartial
Third, an uncertainty-guided class-aware point refinement selectively updates the least reliable pixels, improving rare and ambiguous structures with minimal computational overhead.
Implicationpartial
Explicitly stated as a core component of the method in the abstract and methodology section.
Verificationpartial
partial
Evidencepartial
Off-road semantic segmentation is fundamentally challenged by irregular terrain, vegetation clutter, and inherent annotation ambiguity. Unlike urban scenes with crisp object boundaries, off-road environments exhibit strong class-level similarity among terrain categories, resulting in thick and uncertain transition regions that degrade boundary coherence and destabilize training.
Implicationpartial
Directly and repeatedly stated in the abstract and related work section as the core problem definition.
Verificationpartial
partial
Evidencepartial
Existing decoder designs either rely on low-scale bottlenecks that oversmooth fine structural details, or repeatedly fuse high-detail features, which tends to amplify annotation noise and incur substantial computational cost.
Implicationpartial
Directly stated in the abstract as a limitation of prior work, forming the motivation for the new method.
Verificationpartial
partial
Evidencepartial
The resulting framework achieves noise-robust and boundary-preserving segmentation tailored to off-road environments, recovering fine structural details while maintaining deployment-friendly efficiency.
Implicationpartial
Directly stated in the abstract as a summary claim of the method's benefits, supported by the design rationale and experimental evaluation.
Verificationpartial
partial
Evidencepartial
As indicated by Eq. (2), semantic aggregation is intentionally performed before introducing any boundary-related cues, preventing early contamination of global semantics under ambiguous supervision.
Implicationpartial
Explicitly stated in the methodology section with a specific equation reference.
