Abstract:
1. A method for automatically describing an unknown multimedia object in which the unknown object is associated with a plurality of reference multimedia objects depending on a probability of membership to each considered type of said plural reference multimedia objects such that multimedia objects having memberships in each considered type of said plural reference multimedia objects and a lower affinity to elected multimedia objects having memberships in each type of said plural reference multimedia objects are excluded, the method comprising the steps of: measuring at least one physical characteristic of the unknown multimedia object and comparing the at least one physical characteristic of the unknown multimedia object with measurements of characteristics which best represent each type of said plural reference multimedia objects; using at least one probabilistic relation for each type of said plural reference multimedia objects to obtain a probability that the unknown multimedia object is a member of the type of said plural reference multimedia objects considered based on a result of the comparison of the at least one measured physical characteristics of the unknown object to the measurements of the characteristics which best represent each type of said plural reference multimedia objects; electing the multimedia objects having memberships in each type of said plural reference multimedia objects which form a majority of probabilities associated with each type of said plural reference multimedia objects considered and which are co-designated by an associated affinity relation using obtained probabilities that the unknown multimedia objects are members of different types of said plural reference multimedia objects in combination with a series of affinity relations between each type of said plural reference multimedia objects such that the multimedia objects having memberships in each considered type of said plural reference multimedia objects and the lower affinity to the elected multimedia objects having memberships in each type of said plural reference multimedia objects are excluded.
