Patent ID: 7107251

Claim:
A method of evaluating an audiovisual sequence, the method being characterized in that it implements: a) training, comprising allocating a subjective score NS i to each of N 0 training sequences S i (where i=1, 2, . . . , N 0 ) presenting degradations identified by a training vector MO i comprising objective measurements taken from the signals of the audiovisual sequence which is given to each sequence S i in application of a first vectorizing method, in order to build up a database of N 0 training vectors MO i with corresponding subjective scores NS i ; b) classifying the N 0 training vectors MO i into k classes of scores as a function of the subjective scores NS i that have been allocated to them, so as to form k training sets EA j (where j=1, 2, . . . , k) which have k significant training scores NSR j allocated 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 NSR j that corresponds to the training set EA j containing the vector that is closest to the vector MO in the sense of vector quantification.
