Abstract

This paper presents analysis of impact of the image resolution on the efficacy of the automatic face recognition. During experimental studies three databases were tested, where the head in the photos is set at different angles. The effectiveness of face location detection was examined with the use of the skin color and geometric models. Next, we tested the influence of the head position and the image resolution on the people identification effectiveness. Effect of lowering the image resolution is presented in a FAR / FRR graph form.
