Abstract
A method and system of representing a virtual object in a view of a real environment is provided which includes providing image information of a first image of at least part of a human face captured by a camera, providing at least one human face specific characteristic, determining an image area of the face in the first image as a face region, determining at least one first light falling on the face according to the face region and the at least one human face specific characteristic, and blending in the virtual object on a display device in the view of the real environment according to at least one first light. The method further includes providing a plurality of face sample positions, providing for each of the plurality of face sample positions a radiance transfer function, determining image positions of the face sample positions in the first image, and determining a first light according to intensity information associated with the image positions of the face sample positions in the first image and the radiance transfer functions associated with the face sample positions in the first image.
