Abstract

A method and system for providing contextual filters respective of an identified context of a plurality of multimedia content elements are provided. The method comprises receiving the plurality of multimedia content elements; generating at least one signature for each of the plurality of multimedia content elements; determining a context of each of the plurality of multimedia content elements based on its respective at least one signature, wherein a context is determined as the correlation among a plurality of cluster of signatures; and providing at least one contextual filter respective of the context of each of the plurality of multimedia content elements.

Claims

1. A method for providing contextual filters respective of an identified context of a plurality of multimedia content elements, comprising:

receiving the plurality of multimedia content elements;

generating at least one signature for each of the plurality of multimedia content elements;

determining a context of each of the plurality of multimedia content elements based on its respective at least one signature, wherein a context is determined as the correlation among a plurality of cluster of signatures; and

providing at least one contextual filter respective of the context of each of the plurality of multimedia content elements.

2. The method of claim 1, wherein the at least one contextual filter enables at least one of:

editing of the content of the multimedia content element and editing of the content of each of the plurality of multimedia content elements.

3. The method of claim 1, wherein receiving the plurality of multimedia content elements further comprising:

receiving a uniform resource locator (URL) of the web-page;

downloading the web-page respective of the received URL; and

analyzing the web-page to identify the existence of each of the plurality of multimedia content elements.

4. The method of claim 1, further comprising:

storing in a data warehouse determined contexts and the at least one contextual filter.

5. The method of claim 3, wherein generating the at least one contextual filter further comprising:

generating a signature for the determined context;

retrieving potential contextual filters from a data warehouse;

generating a signature for an initial context respective of each of the retrieved potential contextual filters;

performing signature matching between the signature of the context and the signature generated for each initial context to identify a closest matching initial context; and

determining the contextual filter to the potential contextual filter respective of the closest matching initial context.

6. The method of claim 4, further comprising:

identifying one or more portions of multimedia content in each of the plurality of multimedia content elements;

generating at least one signature for each of the identified portions;

analyzing the at least one signature using at least one of the previously generated signatures maintained in the data warehouse;

determining the context of the multimedia content element based on the signatures and the analysis; and

generating at least one contextual filter respective of the context of the multimedia content element and based on the signatures and the analysis.

7. The method of claim 1, wherein the at least one signature is robust to noise and distortion.

8. The method of claim 1, wherein each of the plurality of multimedia content elements is at least one of:

an image, graphics, a video stream, a video clip, an audio stream, an audio clip, a video frame, a photograph, images of signals, and portions thereof.

9. A non-transitory computer readable medium having stored thereon instructions for causing one or more processing units to execute the method according to claim 1.

10. A system for providing contextual filters respective of an identified context of a plurality of multimedia content elements, comprising:

a network interface for receiving a plurality of multimedia content elements;

a processor; and

a memory coupled to the processor, the memory contains instructions that when executed by the processor cause the system to;

generate at least one signature for each of the plurality of multimedia content elements;

determine a context of each of the plurality of multimedia content elements based on its respective at least one signature, wherein a context is determined as the correlation among a plurality of cluster of signatures; and

provide at least one contextual filter respective of the context of each of the plurality of multimedia content elements.

11. The system of claim 10, wherein the at least one contextual filter enables at least one of:

editing of the content of the multimedia content element and editing of the content of each of the plurality of multimedia content elements.

12. The system of claim 10, wherein the system is further configured to:

receive a uniform resource locator (URL) of the web-page;

download the web-page respective of the received URL; and

analyze the web-page to identify the existence of each of the plurality of multimedia content elements.

13. The system of claim 10, wherein the system is further configured to:

store in a data warehouse determined contexts and the at least one contextual filter.

14. The system of claim 11, wherein the system is further configured to:

generate a signature for the determined context;

retrieve potential contextual filters from a data warehouse;

generate a signature for an initial context respective of each of the retrieved potential contextual filters;

perform signature matching between the signature of the context and the signature generated for each initial context to identify a closest matching initial context; and

determine the contextual filter to the potential contextual filter respective of the closest matching initial context.

15. The system of claim 10, wherein the system is further configured to:

identify one or more portions of multimedia content in each of the plurality of multimedia content elements;

generate at least one signature for each of the identified portions;

analyze the at least one signature using at least one of the previously generated signatures maintained in the data warehouse;

determine the context of the multimedia content element based on the signatures and the analysis; and

generate at least one contextual filter respective of the context of the multimedia content element and based on the signatures and the analysis.

16. The system of claim 10, wherein the at least one signature is robust to noise and distortion.

17. The server of claim 10, wherein each of the plurality of multimedia content elements is at least one of:

an image, graphics, a video stream, a video clip, an audio stream, an audio clip, a video frame, a photograph, images of signals, combinations thereof, and portions thereof.
