18. The method of claim 15 , further comprising: building a background model of a scene from the video input; and if a gross change event is determined to have occurred in the video input, rebuilding the background model of the scene from the video input.
15. A method of video processing using memory and at least one processor, comprising: receiving video input; performing analysis of the video input, using the at least one processor, to determine if a gross change event has occurred in the video input and to produce one or more gross change primitives if a gross change event is determined to have occurred in the video input; generating view identification information using the at least one processor and the one or more gross change primitives; selecting one or more rules using the at least one processor and the view identification information; determining a response, using the at least one processor, based on the one or more selected rules and the one or more gross change primitives.
