Robust Fitting of Implicit Polynomials with Quantized Coefficients to 2D Data
This work presents a new approach to contour representation and coding. It consists of an improved fitting of high-degree (4th to 18th ) implicit polynomials (IPs) to the contour,...

Symbol Recognition Using a Concept Lattice of Graphical Patterns
Abstract. In this paper we propose a new approach to recognize symbols by the use of a concept lattice. We propose to build a concept lattice in terms of graphical patterns. Each m...
