Abstract: In the method of hair color consultation, actual individual images of a person are continuously recorded by a video camera and are input into a computer in a continuous sequence in real time. Automatic image editing and processing is carried out in real time, in which the computer continuously marks hair regions of the individual images by an automatic analysis of close and similar pixel color values, of contiguous texture, and/or of contiguous morphological properties, and changes hair color of the hair regions according to predetermined specifications. Then the modified individual images with the changed hair color are displayed on the at least one screen and/or touch screen in real time so that the desired hair color may be selected. An apparatus for performing the method is also described.
