  • Patent number: 6885766
    Abstract: The present invention refers to a method for automatically correcting color defective areas in an image, which defective color areas were recorded with a color spectrum deviating from the actual color spectrum of said areas without color defects, wherein basic areas in the image are identified on the basis of features which are common for these recorded defective areas, said basic areas supporting an increased likelihood to include defective areas, and the processing is then reduced to the basic areas to identify borderlines and/or centres of the defective areas, and afterwards, it is identified whether the localized basic area or areas deemed to be defective are defective or not, and finally, if a localized basic area has been identified to be defective, a correction mask is created to correct the visual appearance of the defective area.

  • Publication number: 20020150291
    Abstract: The present invention relates to a method for correcting at least one color of a photographic image including at least one pattern area or image pattern with a predictably known color or memory color, said image being transferred to a digital representation, wherein the method comprises the following steps: said at least one pattern area or image pattern is being detected with respect to its presence and its location, and preferably also with respect to its dimensions; an existing color in the at least one detected pattern area or image pattern is being determined; at least one replacement color value (memory color) is being provided, said value being related to the respective at least one pattern area or image pattern and the determined existing color is replaced by said at least one replacement color value, to correct the color in the image pattern or image area.

  • Publication number: 20020126901
    Abstract: The invention relates to a method for automatically detecting a pre-defined image pattern in an original picture, wherein pixel data from said original picture are looked through by means of a processing step, including at least one transform, to find said pre-defined image pattern, wherein according to the invention said processing is split up into at least two stages, wherein a first stage with a coarse processing is to detect locations in the original picture imposing an increased likelihood that the pre-defined image pattern, can be found there, and wherein a second stage with a refined processing is applied to the locations to identify the pre-defined image pattern.
