Abstract
The invention provides a method of evaluating the quality of an audiovisual sequence by: a) training, comprising allocating a subjective score NSto each of Ntraining sequences S(where i=1, 2, . . . , N) presenting degradations identified by a training vector MOwhich is given to each sequence Sin application of a first vectorizing method, in order to build up a database of Ntraining vectors MOwith subjective scores NS; b) classifying the Ntraining vectors MOintoclasses of scores as a function of the subjective scores NSthat have been allocated to them, so as to formtraining sets EA (where j=1, 2, . . . , k) which havesignificant training scores NSRallocated thereto; c) for each audiovisual sequence to be evaluated, generating a vector MO using said first vectorization method; and d) allocating to the audiovisual sequence for evaluation the significant training score NSRthat corresponds to the closest training set EA.
