A method for noise removal from color barcode images includes acquiring a barcode image using a color imaging array and separating the barcode image into color channels. Weighting factors are associated with the color channels and at least one weighting factor is reduced. The weighting factors are applied to the color channels to produce a first transformed image. A portion of the first transformed image is analyzed to produce a first set of decoded data from the barcode.
