Method and system for determining the dimensions of an object shown in a multimedia content item
First Claim
1. A method for determining at least a size dimension of objects shown in multimedia content items, comprising:
- receiving an input multimedia content item;
identifying a plurality of objects shown in the input multimedia content item;
generating at least one first signature for at least one first object of the plurality of objects and at least one second signature for at least one second object of the plurality of objects;
identifying, using the at least one first signature, at least one matching concept, wherein each matching concept of the at least one matching concept includes at least one signature that matches the at least one first signature;
wherein each matching concept comprises a cluster of signatures of multiple multimedia content items and metadata related to the multiple multimedia content items;
wherein each matching concept undergoes a cluster reduction process that comprises reducing a number of signatures of the matching cluster while remaining a minimal number of signatures that still identify all of the multiple multimedia content items;
wherein for each matching cluster the cluster reduction process comprises matching signatures of each of the multimedia content items associated with the matching cluster, with a reduced cluster having one or more signatures removed there from to provide results; and
determining whether to remove the one or more signatures from the concept based on the results;
determining an actual size of the at least one first object respective of the at least one matching concept, wherein the actual size of the at least one first object is determined respective of an actual size of the at least one matching concept maintained in a data warehouse;
determining a size scale between the at least one first object and the at least one second object of the plurality of objects using the at least one first signature and the at least one second signature; and
determining the at least size dimension of the at least one second object of the plurality of objects respective of the size scale and the actual size of the first object.

Abstract
A method and system for determining at least a size dimension of objects shown in multimedia content items are presented. The method includes receiving an input multimedia content item; identifying objects shown in the multimedia content item; generating at least a first signature for at least a first object of the plurality of objects and at least a second signature for at least a second object; identifying at least one concept that matches the at least a first object; determining an actual size of the first object respective of the match to the at least one concept; determining a size scale between the first object and the second object using the at least a first signature and the at least a second signature; and determining the at least size dimension of the second object respective of the size scale and the actual size of the first object.

8. A system for determining at least a size dimension of objects shown in a multimedia content item containing a plurality of objects, comprising:
-
an interface to a network for receiving an input multimedia content item; a processing unit; and a memory connected to the processing unit and configured to contain a plurality of instructions that when executed by the processor configure the system to; identify a plurality of objects shown in the input multimedia content item; identify, using the at least one first signature, at least one matching concept;
wherein each matching concept of the at least one matching concept includes at least one signature that matches the at least one first signature;
wherein each matching concept comprises a cluster of signatures of multiple multimedia content items and metadata related to the multiple multimedia content items;
wherein each matching concept undergoes a cluster reduction process that comprises reducing a number of signatures of the matching cluster while remaining a minimal number of signatures that still identify all of the multiple multimedia content items;
wherein for each matching cluster the cluster reduction process comprises matching signatures of each of the multimedia content items associated with the matching cluster, with a reduced cluster having one or more signatures removed there from to provide results; and
determining whether to remove the one or more signatures from the concept based on the results;determine an actual size of the at least one first object respective of the at least one matching concept, wherein the actual size of the at least one first object is determined respective of an actual size of the at least one matching concept maintained in a data warehouse; determine a size scale between the at least one first object and at least one second object of the plurality of objects using the at least one first signature and at least one second signature; and determine the at least size dimension of the at least one second object of the plurality of objects respective of the size scale and the actual size of the at least one first object. - View Dependent Claims (9, 10, 11, 12, 13, 14, 17, 18)
