1. A method comprising:
- acquiring, by a video acquisition module utilizing at least hardware, a digitized video comprising pixel data;
performing pixel differentiation to locate differentiations in the pixel data in a video frame of the digitized video, by a pixel differentiation module;
defining an area of interest in the pixel data of the video frame, by the pixel differentiation module, the area of interest comprising a pool of light produced by a headlight of a vehicle on the ground with an identifiable edge in front of the vehicle; and
detecting attribute information of the area of interest by an attribute detector to track edges of the pool of light to determine a distance and a sideways separation of the vehicle and to compare the edges with other attribute information for the vehicle to determine a speed of the vehicle.

Abstract
Vehicular situational awareness systems, method and arrangements are disclosed herein. In one embodiment digitized video can be acquired by a camera on a vehicle, and utilizing pixel differentiation at least one area of interest in the digitized video can be identified. The area of interest could be, for example, a group of pixels that represent another vehicle, a sign etc. Attribute information for the area of interest, such as size, movement etc. of an object, can be acquired and then it can be determined if the attribute information is significant enough or important enough to set an alarm condition and notify the driver.
