The paper considers automatic vision based modelling and recognition of sign language expressions using smaller units than words. Modelling gestures with subunits is similar to modelling speech by means of phonemes. To define the subunits a data–driven procedure is proposed. The procedure consists in partitioning time series of feature vectors obtained from video material into subsequences which form homogeneous clusters. The cut points are determined by an optimisation procedure based on… CONTINUE READING
