2D CNN/U-Net

← model structures and inputs · JSON report · mapped fields NPZ
Training-set diagnostic only. Run 18h01, one weak point-dilated target and unvalidated registration. AP/IoU/Dice below measure fit to this same run, not generalization. Native resolution and transfer back to CAD differ by model. Gray CAD nodes are more than 10 mm from direct mapped support.
