Abstract:
A method of manipulating illumination effects associated with an image, the method comprising:filtering image data of an object to provide orientation data and energy data for a base image and an illuminated base image, the illuminated base image being a illuminated variation of the base image; generating an illumination function based upon illumination difference between the filtered base image and the filtered illuminated base image, the energy data of the filtered illuminated base image being related to the energy data of the filtered base image by the illumination function; normalizing the energy data of the filtered base image using a primary energy data relationship between the filtered base image and the filtered illuminated base image; and normalizing the energy data of the filtered illuminated base image using the primary energy data relationship, wherein the energy data of the filtered base image and the energy data of the filtered illuminated base image are normalized to remove the illumination difference between the filtered base image and the filtered illuminated base image.
