%K computer vision systems, contour, shape.
%X This work discuss an ongoing project that has been developed in order to investigate a new approach for object recognition in computer vision systems based on contour sets. This approach tries to take advantage of the two classical paradigms of shape analysis concentrate on the extraction of a single outline that internal information (e.g. eyes and mouth) is crucial for recognition. In our approach, the object is represented by a set of parametrized contours (hence, 1-D data), and statistical measures that capture 2-D region information are extracted from this countour set. We conjecture that future developments of this approach will allows to address non-standard problems for contour techniques (e.g. texture) with contour tools (e.g. parametric curvature). It is worth emphasizing that the proposed approach is not merely edge based vision, for parametric contour techiniques are explored.
