Executive Summary

With the introduction of electronic personal documents (e.g. passports) in recent years the analysis of suitable photographs has become an important field of research. Such photographs for machine readable travel documents have to fulfill a set of minimal quality requirements defined by the International Civil Aviation Organization (ICAO). As some of the specified requirements are related to certain image regions only, these regions must be located in advance. In this paper, the authors present an automatic segmentation method for aligned color face images. The method is based on a convex variational energy formulation which is solved using weighted total variation.
