Methods for identifying relevant metadata for multimedia data of a large-scale matching system
First Claim
1. A method for identifying and associating metadata to input multimedia data elements, comprising:
- comparing an input first multimedia data element to at least one second multimedia data element by generating for each of said input first multimedia data element and said at least one second multimedia data element a first signature and a second signature, said first signature is a robust signature, and comparing between at least a first signature of said first multimedia data element and at least one of a first signature and a second signature of said at least one second multimedia data element;
collecting metadata of said at least one second multimedia data element when a match is found between said first multimedia data element and said at least one second multimedia data element;
associating, when said match is found between said first multimedia data element and said at least one second multimedia data element, at least a subset of said collected metadata of said at least one second multimedia data element with said first multimedia data element; and
storing said first multimedia data element and said associated metadata in a storage.

Abstract
A method for associate metadata to a multimedia content based on finding matches to similar multimedia content. A given input multimedia content is matched to at least another multimedia content with corresponding metadata. Upon determination of a match, the corresponding metadata is used as metadata of the given multimedia content. When a large number of multimedia data is compared a ranked list of metadata is provided. The most appropriate metadata is associated to the given multimedia content based on various criteria. The method can be implemented in any applications which involve large-scale content-based clustering, recognition and classification of multimedia data, such as, content-tracking, video filtering, multimedia taxonomy generation, video fingerprinting, speech-to-text, audio classification, object recognition, video search and any other application requiring content-based signatures generation and matching for large content volumes such as, web and other large-scale databases.

12. A system for collecting metadata for a first multimedia data element, comprising:
-
a plurality of computational cores configured to receive the first multimedia data element, each core having properties to be independent of each other core, each said core generates responsive to the first multimedia data element a first signature element and a second signature element, said first signature element is a robust signature; a storage unit for storing at least one second multimedia data element, metadata associated with said second multimedia data element, and at least one of a first signature and a second signature associated with said second multimedia data element, said first signature is a robust signature; and a comparison unit coupled to said plurality of computational cores and to said storage unit, wherein the comparison unit is configured to compare signatures of multimedia data elements for the purpose of determining matches between multimedia data elements; wherein responsive to receiving the first multimedia data element said plurality of computational cores generate a respective first signature of said first multimedia element and a second signature of said first multimedia data element, for the purpose of determining a match with said at least one second multimedia data element stored in said storage and associating at least a subset of metadata associated with said at least one second multimedia data element with said first multimedia data element. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)

21. A non-transitory computer readable medium having stored thereon computer executable code when executed causing a processor to perform the process of identifying and associating metadata to input multimedia data elements, comprising:
-
comparing an input first multimedia data element to at least one second multimedia data element by generating for each of said input first multimedia data element and said at least one second multimedia data element a first signature and a second signature, said first signature is a robust signature, and comparing between at least a first signature of said first multimedia data element and at least one of a first signature and a second signature of said at least one second multimedia data element; collecting metadata of said at least one second multimedia data element when a match is found between said first multimedia data element and said at least one second multimedia data element; associating at least a subset of said collected metadata with said first multimedia data element; and storing said first multimedia data element and said associated metadata in a storage.
