Research questionHow can paddy rice be segmented reliably in hilly terrain despite terrain-induced appearance changes?In hilly regions, terrain changes the optical appearance of rice and increases confusion with visually similar vegetation. Segmentation must limit false positives on steep slopes while avoiding missed rice areas elsewhere.

Evidence includes internal Area A testing, a geographically held-out and steeper Area B with lower rice prevalence, matched August 2024 imagery without adaptation, ablations, slope-stratified analysis, and cross-year seasonal analysis.research paper · Sep 7, 2026
