• DesertFormer achieves a mean Intersection-over-Union (mIoU) of 64.4% and pixel accuracy of 86.1% on a purpose-built dataset of 4,176 annotated off-road images.result 95%
• DesertFormer represents a +24.2% absolute improvement in mIoU over a DeepLabV3 MobileNetV2 baseline (41.0% mIoU).result 95%
• DesertFormer is based on SegFormer B2 with a hierarchical Mix Transformer (MiT-B2) backbone.method 95%
• The system classifies terrain into ten ecologically meaningful categories: Trees, Lush Bushes, Dry Grass, Dry Bushes, Ground Clutter, Flowers, Logs, Rocks, Landscape, and Sky.technical 95%
• Desert landscapes present unique challenges for semantic segmentation due to low chromatic contrast between terrain categories, extreme lighting variability, and sparse vegetation.technical 90%
• The primary confusion patterns identified in failure analysis are Ground Clutter to Landscape and Dry Grass to Landscape.limitation 90%
• The model was trained on a purpose-built dataset of 4,176 annotated off-road images at 512x512 resolution.method 95%
