This paper summarises our experience of using data analysers to enhance network multimedia services. By analysers we mean simple processing modules that extract information contained in various multimedia streams. They are categorised based on their location with respect to the network, the location being determined by balancing bandwidth requirements and(More)
Stochastic modelling of non-stationary vector time-series based on HMMs has been very successful for speech applications [5]. Recently it has been applied to a range of image recognition problems [7, 9]. Previously reported work [6] has investigated the use of HMMs to model human faces for identication purposes. Faces can be intuitively divided into regions(More)
