1. A method of generating range discontinuity information in an imaged scene, comprising the steps of:

  • a) locating intensity transitions in a pair of stereoscopically related images of said scene;

    b) locating identifiably corresponding intensity transitions in said related images;

    c) computing a parameter related to the range of said corresponding intensity transitions;

    d) defining closed regions of similar intensity in said scene;

    e) assigning to said regions parameter values derived from the computed parameter of corresponding intensity transitions lying within said regions; and

    f) locating the boundary between adjacent regions for which said assigned parameter values are substantially different.
