Zusammenfassung:A destination texture (201) associated with a set of destination coordinates (a') is generated, the set of destination coordinates being indicative of a particular combination of illumination and viewing directions under which the corresponding destination texture is illuminated and observed. Generation of the destination texture is based on a plurality of source textures (211, 221, 231) associated with different sets of source coordinates (A'-F'), each set of source coordinates being indicative of a particular combination of illumination and viewing directions for which the corresponding source texture indicates spatial variations of appearance. The method comprises carrying out a statistical texture synthesis operation based on the source textures, the sets of source coordinates, and the set of destination coordinates to create a destination texture that is dissimilar to the source textures on a pixel-by-pixel basis while having similar statistical properties as the source textures.
