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 quantization representation (DQR) which is motivated by a simplified geometric model of biological compound eye and used in describing the shape of convex hulls of objects. Advantages of DQR include high efficiency and stability in numerical computation, convenience for semidynamic maintenance, suitability for parallel implementation, and applicability to various convex set related problems. Several practical applications are presented which show the feasibility and powerfulness of DQR.
