Abstract

This paper presents a novel face detection method, which integrates the discriminating feature analysis of the input image, the statistical modeling of face and nonface classes, and the Bayes classifier for multiple frontal face detection. First, feature analysis derives a discriminating feature vector by combining the input image, its 1-D Haar wavelet representation, and its amplitude projections. Second, statistical modeling estimates the conditional probability density functions, or PDFs, of the face and nonface classes, respectively. Finally, the Bayes classifier applies the estimated conditional PDFs to detect multiple frontal faces in an image. Experimental results using 853 images (containing a total of 970 faces) from diverse image sources show the feasibility of the proposed face detection method.
