Fast BTF Texture Modelling
Original language description
This paper presents a fast model-based algorithm for realistic multispectral BTF tecapable of direct implementation inside the graphical card processing unit. The algorithm starts with range map estimation of the BTF texture followed by the spectral andspatial factorization of an input multispectral texture image. Single orthogonal monospectral components are decomposed into a multi-resolution grid and each resolution data are independently modelled by their dedicated Gaussian Markov random field model(GMRF). We estimate an optimal contextual neighbourhood and parameters for each GMRF. Finally single synthesized monospectral texture pyramids are collapsed into the fine resolution images and using the inverse Karhunen-Loeve transformation we obtain the smooth multispectral texture. Both multispectral and range information is combined in a bump mapping filter of the rendering hardware. The presented model offers huge BTF texture compression ration which cannot be achieved by any .
