This paper presents a method for recognition of cartographic symbols that is based on a structural model of a general 2D-curve. The presented method utilizes an algebraic description of a curve structure described in [7]. Feature extraction is based in the vectorized skeleton generated by the non-pixelwise thinning algorithm, [14]. From such representation, a structural description of a cartographic symbol is obtained. Finding a match between a model and a given, unknown 2D-shape, is performed through the devised, hybrid procedure, consisting of the structural matching algorithm with followed distance calculation in a parameter space. Experimental results shoen that the method gives satisfying recognition rates.
