An edge classiication and edge attribute estimation scheme is developed , implemented and analyzed based on a tool that is a generalization of wavelet transforms{so called signatures, a term used by Marr in 1976, however using this concept in a wider sense than Marr. Signatures, in this work, are multi-scale representations of local gray-level information… (More)
