Abstract

The system presented is part of a general object recognition system. Images of faces are represented as graphs, labeled with topographical information and local features. New graphs of faces are generated by an elastic graph matching procedure comparing the new face with a composition of stored graphs: the face bunch graph. The result of this matching process can be used to generate composite images of faces and to determine facial attributes represented in the bunch graph, such as sex or the presence of glasses or a beard. Keywords: face analysis, sex discrimination, facial attributes, phantom faces, Gabor wavelets, elastic graph matching, bunch graph. 1 Introduction The system presented here has not primarily been designed for face processing or even sex identification. It is rather part of a larger effort to develop a general recognition system, which can be applied to faces [1] as well as to any other class of objects [2]. It has also been shown that it can deal with many differe...
