Data-Efficient Crosswalk Segmentation from Overhead CCTV via Confidence- and Geometry-Guided Pseudo-Labeling
The 88.91% IoU figure is measured on the held-out manually labelled CCTV validation set. The separately reported 98.52% value is an internal second-stage pseudo-label agreement measure, not human-ground-truth validation accuracy.
