Abstract: The disclosure provides for head pose and gaze angle estimation that includes using a face alignment method with an image of a two-dimensional (2D) face to generate a facial UV position image and facial UV texture image of the 2D face in which to decouple movement of the head and eyes of the 2D face. An eye UV texture image is extracted from the facial UV texture image and stored in a database. The eye region of the facial UV texture image may then be replaced with the eye UV texture image stored in the database to generate a modified facial UV texture image. The modified facial UV texture image is reconstructed to generate a modified 2D face image as training data stored in the database, and the head pose and gaze angles of a person are simultaneously estimated by training a convolutional neural network with the training data.

Abstract: The disclosure relates to technology for monitoring driver attentiveness in a vehicle. A driver distraction system collects vehicle data and scene information from the vehicle while traveling on a route. The vehicle data and scene information are then processed to generate a reference heat map. At the same time, the driver distraction system may capture a gaze of a driver to track a gaze direction and duration of the driver while driving the vehicle on the route. The gaze direction and duration are processed to generate a driver gaze heat map. The driver gaze heat map and reference heat map are analyzed to determine a level of driver distraction of the driver in the vehicle, and a recommendation or warning is output to the driver of the vehicle according to the level of driver distraction.
