Abstract
Systems, methods and media for transitioning detecting content change in a streaming image system are disclosed. One embodiment provides a method for detecting a content change between image frames in a streaming image system. Embodiments may include selecting a change detection algorithm from a plurality of change detection algorithms and comparing a first image frame of m image stream with a second image frame of the image stream using the selected change detection algorithm. Embodiments may also include, in the event of detecting a content change between the first image frame and the second image frame, generating an indication of the content change. Further embodiments may include selecting the change detection algorithm based on a user's selection or system capabilities. Other further embodiments may include transmitting the indication of the content change.
