Abstract
A system for providing augmented reality detects foreground occluders in an image of a video stream. One or more virtual objects are then rendered appropriately with respect to the occluders. Location information associated with the image is used to retrieve a three dimensional representation of the location where the image was taken. Features that are expected to appear in the image based on the three dimensional location but that cannot be located are used to determine regions of the image that are likely to include foreground occluders. Pixels in these regions are used to train a color model that classifies pixels as either part of the background of the image or part of one or more foreground occluders. The pixels in the image are classified using the model, and one or more virtual objects are rendered so that they appear behind any foreground occluders.
