  • Method for embedding digital information in an image
    Patent number: 6044182
    Abstract: A method of embedding digital data in a source image includes the steps of: a) generating a multi-level data image representing the digital data; b) convolving the multi-level data image with an encoding carrier image to produce a frequency dispersed data image; and c) adding the frequency dispersed data image to the source image to produce a source image containing embedded data. The data is recovered from the image by: a) cross correlating the source image containing embedded data with a decoding carrier image to recover the data image; and b) extracting the digital data from the recovered data image.
    Type: Grant

    Date of Patent: March 28, 2000
    Assignee: Eastman Kodak Company

  • Illuminant color detection
    Patent number: 5825916
    Abstract: A method for determining the color of an illuminant of a scene includes the steps of: forming a color digital image of the scene; forming a chromaticity bitmap of the digital image; smoothing the chromaticity bitmap; identifying a plurality of spokes in the smoothed chromaticity bitmap and projecting a plurality of beams across the smoothed chromaticity bitmap, each beam encompassing one of the spokes; identifying the intersection of the area occupied by the beams; and determining the central tendency of the intersection to determine the color of the illuminant.
