Abstract (en)
[origin: WO2005081190A1] According to the invention, hair colors are assigned to a plurality of hair color classes while a hair region is provided with pixels in a digital image, to which coding data that is coded according to the HLS color space is allocated, at least one predefined luminance value according to the hair color class being associated with each pixel in the hair color region of a hair color class in the HLS color space. Verification is made as to whether the original hair color and the target hair color are assigned to the same hair color class, and the original hair color coding data assigned to the original hair color is transformed, within the HLS color space, onto the target hair color coding data allocated to the target hair color in case the original hair color and the target hair color are assigned to different hair color classes while the at least one luminance value of the hair color class of the original hair color is replaced by the at least one luminance value of the hair color class of the target hair color.
