Systems, Methods, and Media for Detecting Content Change in a Streaming Image System

A machine-accessible medium, containing instructions effective, when executing in a data processing system, to cause said data processing system to perform operations comprising:

• selecting by a content change detector a change detection algorithm from a plurality of change detection algorithms;
• comparing by the content change detector a first image frame of an image stream with a second image frame of the image stream using the selected change detection algorithm;
• and
• in the event of detecting a content change between the first image frame and the second image frame, generating by the content change detector an indication of the content change.

A content change detector system, the system comprising:

• a component interface module, the component interface module being adapted to receive an image frame to be compared;
• a plurality of change detection modules, each of the change detection modules having an associated change detection algorithm, the plurality of change detection modules being adapted to compare the received image frame with a previous image frame using its associated change detection algorithm;
• and
• an algorithm, selector in communication with the component interface module, the algorithm selector being adapted to select one of the plurality of change detection algorithms for comparing the received image frame with the previous image frame.
