1. An imaging system having a memory with stored thereon executable instructions, and stored reference imaging data including a historical localization dictionary database having geo-located driving image sequences and other features acting as signatures for distinct locations, such that each reference image is applied to a threshold to produce a binary representation, the imaging system comprising:

  • a sensor to acquire a sequence of input images of a dynamic scene;

    an encoder to determine, for each input image in the sequence, a histogram of each input image in the sequence indicating a number of vertical edges at each bin of the input image and to threshold the histogram to produce a binary representation of the input image; and

    a visual odometer to compare the binary representations of each input image in the sequence and each reference image in the database, by matching one or more input image against one or more reference image in the database,wherein the visual odometer determines a location of the input image based on a match between the one or more input image and the one or more reference image.
