Fig. 17From: Window detection in facade images for risk assessment in tunnelingDistributions of the detected opening-ratio per building. Solid blue lines indicate the distributions of opening-ratios based on the detections of our system corresponding to its classification threshold. Their peaks are highlighted by a purple triangle. The opening-ratios inferred from the system with a calibrated classifier are marked with a green asterisk. Dashed lines indicate manually labeled (red) and actual (yellow) ground truthBack to article page
