Probabilistic Reasoning Models for Face Recognition
We introduce in this paper two probabilistic reasoning models (PRM-1 and PRM-2) which combine the Principal Component Analysis (PCA) technique and the Bayes classifier and show th...

A computational model of monkey grating cells for oriented repetitive alternating patterns
In 1992 neurophysiologists [5] found an new type of cells in areas V1 and V2 of the monkey primary visual cortex, which they called grating cells. These cells respond vigorously to...

Modeling Facial Skin Motion Properties in Video and Its Application to Matching Faces across Expressions
—In this paper, we propose a method to model the material constants (Young’s modulus) of the skin in subregions of the face from the motion observed in multiple facial expressi...
