For each space, we use the single Gaussian model based on the Mahalanobis metric and a Gaussian mixture density model to segment faces from scene backgrounds. In the case of the mixture density model, the skin chrominance distribution is estimated by use of the expectation-maximisation (EM) algorithm. Feature extraction is performed on the segmented images by use of invariant Fourier-Mellin moments. A multilayer perceptron neural network (NN), with the invariant moments as the input vector, is then applied to distinguish faces from distractors. With the single Gaussian model, normalized color spaces are shown to produce the best segmentation results, and subsequently the highest rate of face detection. The results are comparable to those obtained with the more sophisticated mixture density model. However, the mixture density model improves the segmentation and face detection results significantly for most of the un-normalized color spaces. Ultimately, we show that, for each chrominance space, the detection efficiency depends on the capacity of each model to estimate the skin chrominance distribution and, most importantly, on the discriminability between skin and \"non-skin\" distributions.","PeriodicalId":360065,"journal":{"name":"Proceedings Fourth IEEE International Conference on Automatic Face and Gesture Recognition (Cat.

Objects are segmented from a complex background using a stereo disparity histogram that represents the range information of the objects. A matching pixel count (MPC) disparity measure is introduced to enhance the matching accuracy. To detect the facial regions among segmented objects, a skin-color transform technique is used with the general skin color distribution (GSCD) modeled by a 2D Gaussian function in a color synthetic normalization (CSN) color space. The motion detection technique of AWUPC (adaptive weighted unmatched pixel count) is defined on the skin-color transformed image where the adaptive threshold value for the motion detection is determined according to the probability of skin color. AWUPC transforms the input color image into a gray-level image that represents the probability of both the skin color and motion information. The experimental results show that the proposed algorithm can detect a moving human object in various environments such as skin color noise and complex background. It can be useful in MPEG-4 SNHC.","PeriodicalId":360065,"journal":{"name":"Proceedings Fourth IEEE International Conference on Automatic Face and Gesture Recognition (Cat.
