Abstract

In this work we investigate the visual appearance of real world surfaces and the dependence of appearance on scale viewing direction and illumination direction At fine scale\nsurface variations\ncause local intensity variation or image texture The appearance of this texture depends on both\nillumination and viewing direction and can be characterized by the BTF bidirectional texture\nfunction At sufficiently coarse scale\nlocal image texture is not resolvable and local image intensity\nis uniform The dependence of this image intensity on illumination and viewing direction is described\nby the BRDF bidirectional reflectance distribution function We simultaneously measure the BTF\nand BRDF of over \t different rough surfaces\neach observed with over \n\t\t different combinations of\nviewing and illumination direction The resulting BTF database is comprised of over \n\n\n\t\t image\ntextures To enable convenient use of the BRDF measurements\nwe t the measurements to two\nrecent models and obtain a BRDF parameter database These parameters can be used directly in\nimage analysis and synthesis of a wide variety of surfaces The BTF\nBRDF\nand BRDF parameter\ndatabases have important implications for computer vision and computer graphics and and each is\nmade publicly available.
