Abstract

A raw digital image consists of a 2D spatial arragement of pixels each of which results from measuring the light at a specific location of the image plane. Currently most of the artificial sensors (e.g. CCD cameras) have the rigid structure of an orthogonal grid, whereas most natural vision systems are based on non-regular arrangements of sensors [1]. Although arrays are certainly easier to manage technically, topological relations seem to play an even more important role for vision tasks in natural systems than precise geometrical positions.
