摘要： A hand washing monitoring system (1) comprising a camera (2), a processor (4), the processor being adapted to receive from the camera images of hand washing activity. The processor analyses mutual motion of hands to determine if the hands mutually move in desired poses, and if so, the durations of the patterns; and generates a hand washing quality indication according to the analysis. The processor extracts information features from the images and generates feature vectors based on the features, including bimanual hand and arm shape vectors, and executes a classifier with the vectors to determine the poses. The processor uses edge segmentation and pixel spatio-temporal measurements to form at least some of the feature vectors.

摘要： An equipment for the automatic assessment of road signs and panels, the equipment performing, for the purpose, a retroreflection measurement of the white element of the signs or panels, and a measurement of the contrast between the white element of the sign or panel and a characteristic element of same (borders or text) in order to ensure a particular level of legibility. To this end, a vehicle (1) is equipped with a pulsed infrared illumination system (3), a system of stereoscopic cameras (2), a GPS (11), an odometer (12), a computer (5) mounted on an industrial rack, a data storage system (8), an event keyboard (7), and a TFT monitor (6) for viewing results. The infrared illumination system (3) is synchronized with the cameras (2). In this way, the infrared illuminator (3) illuminates the road area in alternate images, thereby providing illuminated road images and non-illuminated road images.
