The extension consists in introducing several spectral parameters for each BTF image which are linearly estimated in the second estimation step according to the original data. The method is easily implementable in a graphical hardware for purpose of real-time rendering. abstract (cze) Modelování hrubých textur pracuje s ohromným obrazovým prostorem - dvojsměrovou texturní funkcí (BTF). Tato 6ti dimenzionální funkce závisí na planárních texturních souřadnicích a na úhlech osvětlení a pohledu. Navrhujeme nový nelineární reflektanční model, který představuje zlepšení Lafortunova reflektančního modelu. Model restauruje všechny obrazy BTF databáze nezávisle pro každý úhel pohledu a tím výrazně redukuje velikost BTF prostoru. Tato metoda dovoluje dosáhnout kompresi BTF dat 1:15 action ARLID cav_un_auth*0129876 name International Conference on Pattern Recognition /17./ place Cambridge dates 23.08.2004-26.08.2004 country GB reportyear 2005 RIV BD permalink http://hdl.handle.net/11104/0013477 ID_orig UTIA-B 20040107 arlyear 2004 mrcbU63 Proceedings of the 17th IAPR International Conference on Pattern Recognition 1 0-7695-2128-2 80 83 Los Alamitos IEEE 2004 mrcbU67 Kittler J. 340 mrcbU67 Petrou M. 340 mrcbU67 Nixon M. 340
