摘要： A machine-implemented method for automated detection of drowsiness, which includes receiving from an imaging device directed at the face of an operator a series of images of the face of the operator onto processing hardware, on the processor detecting facial landmarks of the operator from the series of images to determine the level of talking by the operator, the level of yawning of the operator, the PERCLOS of the operator, on the processor detecting the facial pose of the operator from the series of images to determine the level of gaze fixation by the operator, on the processor calculating the level of drowsiness of the operator by ensembling the level of talking by the operator, the level of yawning of the operator, the PERCLOS of the operator and the level of gaze fixation by the operator, and generating an alarm when the calculated level of drowsiness of the operator exceeds a predefined value.

摘要： An operator behavior recognition system comprising hardware including at least one processor, a data storage facility in communication with the processor and input/output interfaces in communication with the processor, the hardware being configured to implement a set of convolutional neural networks (CNNs) including: an object detection group into which at least one image is received from an image source for detecting at least one object in the image and to delineate the object from the image for further processing, at least one of the objects being detected being a face of a person; a facial features extraction group into which the image of the person's face is received and from which facial features from the person's face are extracted; and a classifier group which assess the facial features received from the facial feature extraction group in combination with objects detected by the object detection group to classify predefined operator behaviors.
