Exemplary detection results of our system. Green rectangles indicate true positive window detections whereas red rectangles indicate false detections. Windows are detected despite slightly occluding balcony rails (a) or partial occlusions due to flags or vegetation (c). Facade elements shaped similarly like windows may lead to misclassifications (b). No detection of store windows (b),(d)
