A method and system for updating a visual element model of a scene model associated with a scene, the visual element model including a set of mode models for a visual element for a location of the scene. The method receives an incoming visual element of a frame of the image sequence and, for each mode model, classifies the respective mode model as either a matching mode model or a distant mode model, by comparing an appearance of the incoming visual element and a set of visual characteristics of the respective mode model. The method removes a distant mode model from the visual element model, based upon a first temporal characteristic of a matching mode model exceeding a maturity threshold and a second temporal characteristic of the distant mode model being below a stability threshold.
