  • Detection of anti aliasing in two-color images for improved compression
    Patent number: 8515161
    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.
    Type: Grant

  • Method for compression of two-color anti aliased images
    Patent number: 7580580
    Abstract: A method for compressing two color anti-aliased images takes advantage of the fact that when two color anti-aliased images are present, it is often the case that the two base colors appear in adjacent or continuous series or “runs” of pixels representing the same color. According to one embodiment to the present invention, these runs are identified and then the color and run length are encoded to produce increased compression efficiency.
