                         semi-automatic tool for helping indexing people in historical 
                         photographs. In the proposed recognizer we cope with the scarcity 
                         of training samples and the lack of precision of the detector 
                         using a training scheme in two stages. The first stage uses an 
                         external face database to compute an average face that is used as 
                         a reference either at the second training stage and at the 
                         recognition step. We also added an auxiliary distance measure we 
                         call relative distance to reorder the results generated by the 
                         original Euclidean-based distance measure for 2D-PCA. Experimental 
                         results with the ORL database as the external face database and a 
                         real collection of historical photographs have shown the viability 
                         of the proposed tool. These experiments also indicated that both 
                         improvements proposed were indeed able to increase recognition 
                         rates.",
