  • PRINTING INK, ITS USE FOR THE AUTHENTICATION OF ARTICLES, ARTICLES OBTAINED THEREBY AND AUTHENTICATION METHODS
    Publication number: 20170260413
    Abstract: A printing ink having a first fluorescent dye acting as donor and a second fluorescent dye acting as acceptor. The first fluorescent dye, upon excitation by electromagnetic radiation falling within an excitation wavelength range ?1a of the first fluorescent dye, is capable of emitting electromagnetic radiation in at least one first emission wavelength range ?1e, said first emission wavelength range ?1e of the first fluorescent dye overlapping with at least one excitation wavelength range ?2a of the second fluorescent dye, to thereby excite the second fluorescent dye to emit electromagnetic radiation in a second emission wavelength range ?2e.

  • Identifying one- or two-dimensional bar codes via weighted image data combination
    Patent number: 9495572
    Abstract: A method for identifying a one- or two-dimensional barcode in input image data, the method comprising the steps of: obtaining first image data of a first image of the object, said first image being acquired using a first illumination wavelength; obtaining second image data of a second image of the object, said second image being acquired using a second illumination wavelength being different from said first illumination wavelength; calculating a weighting factor based on a statistical processing of pixel values of the first image data and pixel values of the second image data; and generating third image data by calculating a weighted combination using the pixel values of said first image data, the pixel values of said second image data, and said weighting factor.
