Abstract
A method and apparatus are disclosed for generating and maintaining multi-layered background models for use in background-foreground segmentation. The multi-layered background model captures various states of the background. Each additional layer in the background model is associated with a background object that has been moved. As a background object is moved, the corresponding pixel information can be transferred from one portion of an image to another corresponding to the new location of the background object. Each layer can be separately applied to a classifier to obtain an identification of the corresponding object.
