Model-based Estimation of Texels and Placement Grids for Fast Realistic Texture Synthesis
نویسنده
چکیده
This paper describes basic steps of a new technique, called bunch sampling, that allows to realistically synthesise spatially homogeneous textures. A geometric shape of the bunch (acting as a texel) and spatial placement grid governing relative positions of the bunches are estimated from the training texture by using a generic Gibbs random field texture model with multiple pairwise pixel interactions. During the synthesis, the bunches are randomly sampled from the training texture and placed into the large-size goal image with due account of their spatial interdependence.

متن کاملCoherent Texture Synthesis for Photograph Relighting and Texture Replacement
In this thesis, we present a texture synthesis method for realistic rendering without acquiring the actual reflectance properties. The method is from the observation that most objects have texture repeatedly laid on different locations of their surface explicitly or implicitly. These samples form a pretty sparse set of BTFs. Our goal is to extract the underlying texture from photographs of the ...
متن کاملTexture analysis using Renyi's generalized entropies
We propose a texture analysis method based on Rényi’s generalized entropies. The method aims at identifying texels in regular textures by searching for the smallest window through which the minimum number of different visual patterns is observed when moving the window over a given texture. The results show that any of Rényi’s entropies can be used for texel identification. However, the second o...

متن کاملFast BTF Texture Modelling
This paper presents a novel fast model-based algorithm for realistic multispectral BTF texture modelling potentially capable of direct implementation inside the graphical card processing unit. The algorithm starts with range map estimation of the BTF texture followed by the spectral and spatial factorisation of an input multispectral texture image. Single orthogonal monospectral band-limited fa...
