  • Method and apparatus for preserving font structure
    Patent number: 7639259
    Abstract: A method of preserving the structure of a font character being scaled comprises analyzing the font character to determine if the font character is complex. If the font character is complex, information concerning the strokes forming the font character is extracted. The strokes are then scaled to a desired size using the extracted stroke information thereby to form a scaled font character.

  • Method and apparatus for increasing contrast in a digital image
    Publication number: 20070031059
    Abstract: A method of enhancing contrast in a digital image comprises isolating pixels of the image having intensities falling within a low intensity range, determining at least one feature of the pixel distribution with the range and adjusting intensities of pixels in the image to make the pixels within the range more visually distinct. An apparatus for enhancing contrast in a digital image is also provided.

  • Method and apparatus for resizing images
    Publication number: 20060072853
    Abstract: A method of fractionally resizing an image comprises locating areas of sensitivity in the image. Adjustment lines in the image are selected at least partially based on the location of the located areas of sensitivity. The image is then resized along the adjustment lines. An apparatus for fractionally resizing an image is also provided.

  • Method and system for recognizing a candidate character in a captured image
    Publication number: 20060045322
    Abstract: A system and method of recognizing characters in a captured image, includes selecting a portion of the image encompassing a string of characters in the captured image to be recognized. The selected portion is examined to identify segments that potentially include the characters of the string. During the examining multiple tests on pixels in the selected portion are performed. The identified segments are then examined to recognize the string of characters.
