Recognition of sketches in photos
Face recognition by sketches in photos makes an important complement to face photo recognition. It is challenging because sketches and photos have geometrical deformations and texture difference. Aiming to achieve better performance in mixture pattern recognition, we reduce difference between sketches and photos by synthesizing sketches from photos, and vice versa, and then transform the sketch-photo recognition to photo-photo/sketch-sketch recognition. Pseudo-sketch/pseudo-photo patches are synthesized with embedded hidden Markov model and integrated to derive pseudo-sketch/pseudo-photo. Experiments are carried out to demonstrate that the proposed methods are effective to produce pseudo-sketch/pseudo-photo with high quality and achieve promising recognition results. © 2011 Springer-Verlag Berlin Heidelberg.
