A new data processing method based on a biological model of the compound eye: Direction quantization representation

This paper presents a new data representation method called direction quant ization representation (DQR) which is motivated by a simplified geometric m odel of biological compound eye and used in describing the shape of convex hulls of objects. Advantages of DQR include high efficiency and stability i n numerical computation, convenience for semidynamic maintenance, suitabili ty for parallel implementation, and applicability to various convex set rel ated problems. Several practical applications are presented which show the feasibility and powerfulness of DQR.
