1. A method for detecting electronic device use by a driver of a vehicle, the method comprising: acquiring a first image including a vehicle from an associated image capture device positioned to view oncoming traffic; locating a first region of the vehicle in the first image; processing pixels of the first region of the first image for computing a feature vector describing a windshield region of the vehicle; applying the feature vector to a classifier for classifying the first image into respective classes including at least classes for candidate electronic device use and candidate electronic device non-use; acquiring a second image including the vehicle from an associated image capture device positioned to view oncoming traffic; locating a second region of the vehicle in the second image; processing pixels of the second region of the second image for computing a feature vector describing a side window region of the vehicle; applying the feature vector to a classifier for classifying the second image into respective classes including at least classes for candidate electronic device use and candidate electronic device non-use; and, outputting the classification of the first image and the classification of the second image.
