  • SYSTEM AND METHOD FOR FILTERING AND BINARIZATION OF IMAGES IN THE PRESENCE OF SPECULAR NOISE
    Publication number: 20070154108
    Abstract: In order to render information contained in images more detectable in the presence of noise, the present invention discloses a system and method to binarize the images in the presence of noise. The method of this invention comprises the steps of applying a dynamic range reducing filter to the digitized image values, obtaining a range reduced image; applying an edge detecting filter to the range reduced image, obtaining a filtered image; and then, adaptively binarizing the digitized image utilizing the corresponding filtered image to obtain an adaptive threshold.
