1. A method of determining a vanishing point related to an image, the method comprises the steps of:

  • (a) detecting line segments in the image;

    (b) determining intersections from pairs of line segments;

    (c) assigning a probability to each intersection of the pairs of line segments;

    (d) determining a local maximum corresponding to a plurality of probabilities; and

    (e) outputting an estimated vanishing point vector ν

    E that corresponds to the determined local maximum such that an estimated location of the vanishing point about the estimated vanishing point vector ν

    E results.
