1. A system for detecting an infringement by a vehicle operator actively operating a vehicle, the system comprising:
one or more camera;
one or more sensor for detecting the actively-operated vehicle and triggering the one or more camera to capture a first image of at least a part of the vehicle operator when the actively-operated vehicle reaches an image capture point;
one or more flash for illuminating the vehicle or a part thereof with light at a narrow band when the actively-operated vehicle reaches the image capture point, wherein at least one of the one or more camera comprises a narrow band filter that lets through only or substantially only the wavelengths of light produced by the one or more flash and eliminates the majority of ambient light and/or light produced by the sun, and wherein the light produced by the one or more flash is able to penetrate a windshield of the actively-operated vehicle;
one or more computer processor for automatically analyzing the first image to detect an infringing act, wherein the automatic analyzing comprises:
determining the location of the vehicle operator in the first image;
creating a cropped image, based on the first image, showing only the vehicle operator and the vehicle operator's immediate surrounds;
determining the brightest pixels and the darkest pixels of the cropped image and applying an offset to the pixels of the cropped image to linearly scale the pixels between the brightest pixels and the darkest pixels to yield an enhanced cropped image;
classifying the enhanced cropped image to identify the enhanced cropped image as:
containing an infringement, or, not containing an infringement, wherein a confidence factor or threshold is used to determine whether the enhanced cropped image contains an infringement or does not contain an infringement,
wherein the infringement is one or more of: illegal phone or mobile device use; failure to wear a seatbelt; and, incorrect restraint.
