Abstract:
A method for extracting an image of a foreground object from composite images, using a computer, comprising the steps of:(a) recording a first composite image that includes the foreground object disposed in front of a first background having a first arbitrary coloring;(b) recording a second composite image that includes the foreground object disposed in front of a second background having a second arbitrary coloring that is different than the first arbitrary coloring;(c) obtaining a set of color coordinates for each point in the first composite image and in the second composite image, said color coordinates defining a color for each point; and(d) triangulating the set of color coordinates for each point in each of the first and the second composite images, the step of triangulating returning an alpha value and a set of color coordinates for each point in the image of the foreground object, to define the image of the foreground object apart from any background.
