Abstract

A method that generates a chromakey image and then generates a color corrected, spill suppressed chromakey image. The application identifies the edges of non-transparent objects in the image and determines whether the edges are dark. If the edges are dark, then the application subtracts the color corrected, spill suppressed chromakey image from the chromakey image. The subtraction generates an outline image that includes a bright outline of the objects with the dark edges, while the objects themselves in the outline image are almost entirely black. The application then darkens, based on the outline image, the pixels of the color corrected, spill suppressed chromakey image.
