Abstract
A method for identifying anti aliased images of two or three colors makes use of the fact that in most anti-aliasing techniques, the color values of the source images are known with sub-pixel accuracy, e.g., the boundaries of text characters are described with arbitrary high precision and averaging ensures that the destination pixel values are interpolations of the two source colors so that all of the color values of the image lie on a single line, or a single plane, in 3-dimensional color space.
