METHOD FOR DETECTING DRIVER CELL PHONE USAGE FROM SIDE-VIEW IMAGES
First Claim
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.

11. A system configured to perform image analysis for detecting electronic device use by a driver of a vehicle comprising:
-
at least one an image capture device operably connected to a data processing device that captures a first image of a target vehicle including a windshield region and a second image of the target vehicle including a side window region; and a processor-usable medium embodying computer code, said processor-usable medium being coupled to said data processing device, said computer program code comprising instructions executable by said processor and configured for; locating a windshield region of the vehicle in the first image; processing pixels of the windshield region of the first image for computing a feature vector describing the windshield region of the vehicle; applying the feature vector to a classifier for classifying the image into respective classes including at least classes for candidate electronic device use and candidate electronic device non-use; locating a side window region of the vehicle in the second image; processing pixels of the windshield region of the second image for computing a feature vector describing the 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 classifications of the first and second images. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
