Building Footprint Extraction — FootprintNet checkpoints
Checkpoints for the BONAI building-footprint extraction project. Each folder holds the best checkpoint for one model run. The model family lineage is V0–V3 (ResNet-50 base), V4-Attention (RegNetY-6.4GF), V5-Attention (18-channel pruned), and V6 (SegFormer mit_b2) which is the current family.
Current best model: v6_8ch
