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.
