20130021340 | METHOD AND APPARATUS FOR OBTAINING LIGHTING INFORMATION AND MATERIAL INFORMATION IN IMAGE MODELING SYSTEM - An apparatus and method for obtaining lighting information and material information in an image modeling system are provided. A material constant of a same material region and lighting information of the same material region may be extracted by applying color channel pixel values, depth values, and viewpoint information to a linear system in which a pixel value is defined by a material constant and a combination of a geometry component with a lighting component. | 01-24-2013 |
