Abstract
A system is provided for selecting a foreground region of an image, given a set of pixels defining the boundary of the foreground region of the image. The system includes a component to dilate the pixel set and a component to determine a foreground value (F) and to determine an opacity value (a) based on estimated foreground and background values for each pixel of the dilated set to facilitate a separation of the region from background portions of the image.
