Flow Graphs: Analysis with Near Sets

This paper introduces a framework for flow graphs induced by perceptual systems as well as analysis of such graphs using near set theory. A distinctive feature of such graphs are layers; therefore we shall generally call them flow graphs with layers . In a specific context of perceptual systems, these graphs will referred be to as perceptual flow graphs . A method for determining nearness of flow graphs with layers (perceptual graphs) is given in terms of a practical application to digital image analysis.
