1. A method for segmenting foreground and background regions on a digitized image, the method being carried out by a computer having a processor and a system memory, comprising: estimating a complete background surface of the image, by segmenting the image into initial regions, identifying background regions from the initial regions, and interpolating a complete background surface with the background regions; rectifying pixels of the image with the estimated background surface to normalize the image; and comparing normalized pixels with a threshold color to determine a final segmentation of background regions.
