Comparing faces: a computational and perceptual study / Brodo, Linda; Tistarelli, Massimo; Bicego, Manuele; Lagorio, Andrea; Grosso, Enrico; Brelstaff, Gavin. - (2006), pp. 188-191. (Intervento presentato al convegno Proceedings of International Conference on Computer Vision Theory and Application (VISAPP06)).
Abstract:
The problem of extracting distinctive parts from a face is addressed. Rather than examining a priori specified
features such as nose, eyes, month or others, the aim here is to extract from a face the most distinguishing or
dissimilar parts with respect to another given face, i.e. finding differences between faces. A computational
approach, based on log polar patch sampling and evaluation, has been compared with results obtained from a
newly designed perceptual test involving 45 people. The results of the comparison confirm the potential of the
proposed computational method.
