1. A method of detecting signs in an image comprising the steps of:

  • a) providing a multiplicity of sign images;

    b) computing the MSER of each said sign image to provide a template database;

    c) computing the affine coordinate system of each said template database image MSER;

    d) computing a normalized image of each said template database image MSER;

    e) providing a digitized input image believed to contain sign image elements;

    f) computing the MSER of each said sign image element to provide a set of input image MSERs;

    g) computing the affine coordinate system of each said input image MSER;

    h) computing a normalized image of each said input image MSER;

    i) comparing each template database image MSER with each input image MSER in turn until at least one match is obtained with the best match being selected in the case of multiple matches occurring.
