A method is provided herein for selecting a combination of a subset of weather stations from among a plurality of weather stations for estimating the weather at a specific location. The method may include: receiving an indication of a plurality of weather stations within a predefined area, where the predefined area includes a first location; determining, for each of the plurality of weather stations, a distance of the weather station from the first location; calculating, for a plurality of different combinations of subsets of the plurality of weather stations, an average distance of the weather stations of each of the plurality of different combinations from the first location; calculating, for each of the different combinations of subsets, an average location relative to the first location; and selecting a combination of a subset of the plurality of weather stations based on the average distance and the average location.

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.

A method for signature-enhanced multimedia content searching. The method includes searching through a plurality of input multimedia content elements by comparing a query to at least one tag assigned to each input multimedia content element, wherein at least one of the at least one tag assigned to each input multimedia content element is assigned based on at least one signature generated for the input multimedia content element, wherein each signature represents a concept, wherein each concept is a collection of signatures and metadata representing the concept.

A system and method customizing a display of a user device based on multimedia content elements. The method may include detecting a trigger event; identifying a user profile of the user device, wherein the user profile includes one or more signatures indicating a user interest; accessing signatures for a plurality of multimedia content elements; comparing the signatures of at least one of the plurality of multimedia content elements with the one or more signature of the user profile; and customizing the display of the user device, wherein the customized display includes the at least one interesting multimedia content element.

A system and method for determining sequentially relevant content. The method includes generating at least one signature for a multimedia content item stored in a mobile device; matching the generated at least one signature to a plurality of signatures of content items; and determining, based on the matching, at least one sequentially relevant content item.

A system and method for generating personalized multimedia content element clusters. The method includes determining, based on at least one interest, at least one personalized concept, wherein each personalized concept represents one of the at least one user interest; obtaining at least one multimedia content element related to a user; generating at least one signature for the at least one multimedia content element, each generated signature representing at least a portion of the at least one multimedia content element; determining, based on the generated at least one signature, at least one multimedia content element cluster, wherein each cluster includes a plurality of multimedia content elements sharing a common concept of the at least one personalized concept; and creating at least one personalized multimedia content element cluster by adding, to each determined cluster, at least one of the at least one multimedia content element sharing the common concept of the cluster.

A system and method for clustering multimedia content. The method includes: detecting at least one clustering trigger event related to at least one multimedia content element to be clustered; generating at least one signature for the at least one multimedia content element, each signature representing at least a portion of the at least one multimedia content element; determining, based on the generated at least one signature, at least one multimedia content element cluster, wherein each multimedia content element cluster includes a plurality of clustered multimedia content elements sharing at least one common concept with the at least one multimedia content element; and adding, to each determined cluster, the at least one multimedia content element.

A method and system for matching sequentially relevant content to at least one multimedia content item (MMCI) captured by a mobile device are provided. The method includes extracting at least one MMCI from the mobile device; generating a signature for the extracted at least one MMCI; matching the generated signature to a plurality of signatures of content items; and determining, based on the matching, at least one sequentially relevant content item.

Control of a three-dimensional virtual broadcast presentation is disclosed. The three-dimensional virtual broadcast presentation may be generated based on dynamic information such as traffic information, weather information, or other information that may be featured on a three-dimensional virtual broadcast presentation. A signal generated by a control device maneuvered by a presenter and reflecting positional information of the control device is received. A view of the three-dimensional virtual broadcast presentation is manipulated in response to the received signal, the manipulation of the virtual broadcast presentation at least partially based on positional information of the control device.
