DEVICE FOR STRUCTURING A MULTIMEDIA DOCUMENT REPRESENTING AN EVENT

摘要

The invention concerns a method and a device for structuring a representation of an event, said method comprising: a step which consists in spatio-temporal modelling of the type of event by hierarchical combination of the structural rules expressed in the form of hidden Markov models (HMM) with states associated at least with an observation symbol, a learning step with execution of an automated segmentation and class extraction to determine parameters A, B, pi of the HMM's, and a step of analyzing and restructuring a representation to be structured which consists in determining from the HMM parameters a sequence of Qs states which maximize Pr(Q,O/A,B, pi ), said sequence of Qs states corresponding to the structure of the representation. The invention also concerns a computer programme for implementing the method.
