Claim One:
1. A device comprising: an imaging subsystem to provide image data representative of light incident on said imaging subsystem; one or more memory components, comprising at least a first memory component operatively for storing an input frame of the image data; and a processor, enabled for: receiving the input frame from the first memory component; generating a reduced resolution frame based on the input frame, the reduced resolution frame comprising fewer pixels than the input frame, in which a pixel in the reduced resolution frame combines information from two or more pixels in the input frame; attempting to identify transition pairs comprising pairs of adjacent pixels in the reduced resolution frame having differences between the pixels that exceed a pixel transition threshold; attempting to identify one or more linear features between two or more identified transition pairs in the reduced resolution frame; and providing an indication of one or more identified linear features in the reduced resolution frame.
