Active vision techniques for visually mediated interaction

In this paper we introduce adaptive vision techniques used, for example, in video-conferencing applications. Radial basis function (RBF) networks have been trained for gesture-based communication with colour/motion cues to direct face detection and capture 'attentional frames'. These focus the processing for visually mediated interaction via an appearance-based approach with Gabor filter coefficients used as input to time-delay RBF networks. We use these methods for behaviour (user-camera) coordination in an integrated system.
