Biologically motivated face selective attention model

Abstract

In this paper, we propose a face selective attention model, which is based on biologically inspired visual selective attention for human faces. We consider the radial frequency information and skin color filter to localize a candidate region of human face, which is to reflect the roles of the V4 and the inferooral (IT) cells. The ellipse matching based on symmetry axis is applied to check whether the candidate region contain a face contour feature. Finally, face detection is conducted by face form perception model implemented by an auto-associative multi-layer perceptron (AAMLP) that mimics the roles of faces selective cells in IT area. Based on both the face-color preferable attention and face-form perception mechanism, the proposed model shows plausible performance for localizing face candidates in real time. © 2008 Springer-Verlag Berlin Heidelberg.
