Automatic detecting neutral faces will improve the accuracy of face recognition/authentication, speaker ID analysis, and make it is possible to do facial expression analysis automatically. This paper describes an automatic system to find neutral faces in images by using location and shape features

neutral pictures of objects [2] and, more recently, with emotionally negative words [3]. In the present study, we investigated the lateralization of these effects during the recognition of happy and neutral faces. The parietal effect refers to the nding that compared with ERPs for correctly rejected new

Abstract. This paper presents a technique for decomposing an unseen 3D face under any facial expression into an estimated 3D neutral face and expression deformations (the shape residue between the non-neutral and the estimated neutral 3D face). We show that this decomposition gives a robust facial

We present a Gaussian Mixture Model (GMM) fitting method for estimating the unknown neutral face shape for frontal facial ex-pression recognition using geometrical features. Subtracting the es-timated neutral face, which is related to the identity-specific compo-nent of the shape leaves us

ABSTRACT: Based on the premise that human head tilt is homologous to animal dominance displays, we hypothesized that when a head is bowed, the face should be perceived as submissive, sad, displaying inferiority emotions (i.e., shame, embar-rassment, guilt, humiliation, and respect) and

of a face-recognition system trained with neutral faces. There are other factors like pose and illumination which also lead to performance drops. Researchers have proposed methods to tackle the effects of pose and illumination; however, there has been little work on how to tackle expressions
