Abstract
In this paper, we present an efficient algorithm of extracting the multiple facial features such as eyes, nose, and mouth. The face candidates are first obtained based on skin-color filtering inYC b C r color domain and skin-temperature values and then the elliptic measures are applied to extract a true face candidate and its boundary. A Sobel edge mask is performed and consequently horizontal projection operation is applied to locate the eyes referring to the maximum horizontal projection value in Y component. Once two eyes are located, the distance that crosses the center of eyes and extends to the face boundary, D 1 is determined. A heteroassociative memory neural network model is utilized to find the facial features. An input neuron vector X accepts D 1 and the output neurons vector Y maps it to the facial features such as eyes, nose and mouth.
