METHOD FOR IDENTIFYING A MULTIMEDIA DOCUMENT IN A REFERENCE BASE, CORRESPONDING COMPUTER PROGRAM AND IDENTIFICATION DEVICE
First Claim
1. A method for identifying a multimedia document, aimed at checking on whether or not the multimedia document to be identified is similar to at least one reference multimedia document referenced in a base of reference multimedia documents, comprising the following steps:
- allotting a number of votes to at least one reference multimedia document, each of said votes being significant of a proximity between a descriptor of said reference multimedia document and a descriptor of said multimedia document to be identified, andselecting, from among said at least one reference multimedia document, multimedia documents similar to said multimedia document to be identified, wherein the selecting step comprises the following sub-steps;
determining a probabilistic distribution of the number of votes allotted to a reference multimedia document, as a function of the total number of documents referenced in said base and of the total number of votes, given an assumption of random voting, andobtaining a threshold of selection of said similar multimedia documents, from among the reference multimedia documents, on the basis of said probabilistic distribution.

Abstract
A method is provided for identifying a multimedia document, aimed at verifying whether the multimedia document to be identified is similar or not to at least one multimedia document referenced in a base of reference multimedia documents. The method includes assignment of a number of votes to at least one reference multimedia document and selection of multimedia documents similar to the multimedia document to be identified. The selection step includes: determining a probabilistic distribution of the number of votes assigned to a reference multimedia document, as a function of the total number of documents referenced in the base and of the total number of votes, under a random voting assumption; and obtaining a threshold of selection of the similar multimedia documents from among the reference multimedia documents, on the basis of the probabilistic distribution.

11. A computer program product recorded on a computer-readable carrier, comprising program code instructions for implementing a method for identifying a multimedia document, aimed at checking on whether or not the multimedia document to be identified is similar to at least one reference multimedia document referenced in a base of reference multimedia documents, the method comprising:
-
allotting a number of votes to at least one reference multimedia document, each of said votes being significant of a proximity between a descriptor of said reference multimedia document and a descriptor of said multimedia document to be identified, and selecting, from among said at least one reference multimedia document, multimedia documents similar to said multimedia document to be identified, wherein the selecting step comprises the following sub-steps; determining a probabilistic distribution of the number of votes allotted to a reference multimedia document, as a function of the total number of documents referenced in said base and of the total number of votes, given an assumption of random voting, and obtaining a threshold of selection of said similar multimedia documents, from among the reference multimedia documents, on the basis of said probabilistic distribution.

12. A device for identifying a multimedia document, aimed at checking on whether or not the multimedia document to be identified is similar to at least one reference multimedia document referenced in a base of reference multimedia documents, comprising:
-
means for allotting a number of votes to at least one reference multimedia document, each of said votes being significant of a proximity between a descriptor of said reference multimedia document and a descriptor of said multimedia document to be identified, and selecting means for selecting, from among said at least one reference multimedia document, multimedia documents similar to said multimedia document to be identified, wherein said selecting means comprises; means for determining a probabilistic distribution of a number of votes allotted to a reference multimedia document, as a function of a total number of documents referenced in said base and of the total number of votes, given an assumption of random voting, and means for obtaining a threshold of selection of said similar multimedia documents, from among the reference multimedia documents, on the basis of said probabilistic distribution.
