Abstract

A task-based video analytics system and method are provided, which can include dynamic allocation and sharing of video analytics resources. Video analytics tasks are created in response to trigger information, which can be based on stored business rules, events and/or data of interest. The tasks are forwarded to a video analytics task manager, which manages and distributes tasks to appropriate video analytics resources according to parameters such as scheduling, priority and/or events. Video from the appropriate video source, either a video stream or stored video, is only obtained after the video analytics task is received at the video analytics resource. Video analytics are performed on the video itself, not on video metadata. Data mining of non-video metadata can be used to identify stored video of interest. Configuration tuning can be used to modify a business rule and validate whether the modified rule would affect previous correct data.

Claims

1. A task-based video analytics processing system, comprising:

an event and data processor to initiate a video analytics task in response to generated trigger information and to generate a video analytics task request;

a video analytics task manager, in communication with the event and data processor, to receive and manage video analytics task requests and to route a selected video analytics task to its intended destination; and

a shared video analytics resource in communication with the video analytics manager and with at least one video source to obtain video to be analyzed in response to receipt of the selected video analytics task, and to perform requested video analytics on the obtained video.

2. The system of claim 1 wherein the event and data processor comprises a business rules module to convert the generated trigger information to the video analytics task request based on stored business rules.

3. The system of claim 1 wherein the shared video analytics resource comprises a plurality of shared video analytics resources including a selected shared video analytics resource to which the video analytics task manager routes the selected video analytics task.

4. The system of claim 1 wherein the event and data processor comprises a result surveillance module to associate an analyzed video task result with a pending video processing task.

5. The system of claim 1 further comprising a dedicated video analytics resource in communication with the event and data processor to generate the trigger information on the basis of which the video analytics task request is initiated in response to a result from activity at a real-time video source.

6. The system of claim 1 further comprising a business intelligence database to receive analyzed video task results and to generate reports based on stored business rules.

7. The system of claim 1 wherein the video analytics task manager comprises a scheduling module to schedule received video analytics task requests based on task scheduling data associated with the received video analytics task requests.

8. The system of claim 1 wherein the video analytics task manager comprises a prioritizing module to prioritize received video analytics task requests based on task priority data associated with the received video analytics task requests.

9. The system of claim 1 wherein the video analytics task manager comprises a buffering module to buffer a received video analytics task request in response to detection of conditions preventing execution of the associated video analytics task.

10. The system of claim 3 wherein the video analytics task manager comprises a license manager to manage a pool of video analytics licenses shared among the plurality of shared video analytics processing resources on an as-needed basis.

11. The system of claim 1 wherein the event and data processor further comprises a data mining module to selectively identify events of interest based on stored non-video metadata and to generate corresponding trigger information to request analysis of associated video.

12. The system of claim 1 wherein the event and data processor further comprises an administration module to generate a business rules modification task based on a received modification request in order to be able to detect a missed alert, and to generate a business rules modification validation task to ensure that the modified business rules detect the missed alert and still properly detect all previous alerts.

13. A method of task-based video analytics processing, comprising:

initiating a video analytics task request in response to received trigger information;

routing the video analytics task request to an associated shared video analytics resource;

obtaining video to be analyzed in response to receipt of the video analytics task request; and

performing the requested video analytics on the obtained video.

14. The method of claim 13 further comprising generating an analyzed video task result based on performance of the requested video analytics.

15. The method of claim 13 wherein the received trigger information comprises an analyzed video task result.

16. The method of claim 13 wherein the received trigger information comprises non-video metadata.

17. The method of claim 13 wherein the received trigger information is generated based on stored business rules.

18. The method of claim 13 wherein initiating the video analytics task comprises generating the video analytics task based on the received trigger information.

19. The method of claim 13 wherein performing the requested video analytics at the associated shared video analytics resource is independent of analytics performed at another video analytics resource.

20. The method of claim 13 wherein performing the requested video analytics on the obtained video comprises analyzing the video at a processing speed higher than a real-time processing speed.

21. The method of claim 13 wherein routing the video analytics task request to the associated shared video analytics resource includes determining whether conditions exist that prevent the video analytics task request from being executed by the associated video analytics resource.

22. The method of claim 13 further comprising:

selectively identifying events of interest based on stored non-video metadata; and

generating corresponding trigger information to request analysis of associated video.

23. The method of claim 13 further comprising:

generating a business rules modification task based on a received modification request in order to be able to detect a missed alert; and

generating a business rules modification validation task to ensure that the modified business rules detect the missed alert and still properly detect all previous alerts.

24. A computer-readable medium storing statements and instructions which, when executed, cause a processor to perform a method of task-based video analytics processing according to claim 13.
