Abstract
In this paper we present a new model for video sequence processing that is aimed at extraction of the data describing the mouth shape in the image. The proposed technique can be used in any lip-reading related application. One of such applications, chosen for our experiments, is speech onset and offset detection. The experiments that are described here are aimed at detecting boundaries of the speech on the basis of visual modality only. This paper describes the data processing technique and the results of the experiments.
