Abstract

This paper describes a novel approach to visual speech recognition. The intensity of each pixel in an image sequence is considered as a function of time. One-dimensional Fourier transform is applied to this intensity-versus-time function to model the lip movements. We present experimental results performed on two databases of ten English digits and letters, respectively.
