摘要： A method and system for updating a visual element model of a scene model associated with a scene captured in an image sequence. The visual element model includes a set of mode models for a visual t corresponding to a location of the scene. The method identifies a first mode model from the set of mode models for the visual element model as a candidate deletion mode model. The method then removes the identified candidate deletion mode model from the set of mode models for the visual element model, to update the visual element model for the video sequence, when a first temporal attribute associated with the candidate deletion mode model satisfies a first threshold and a second temporal attribute associated with a second mode model in the set of mode models satisfies a second threshold (Tk).
