The Bidirectional Texture Function (BTF) is the recent most advanced representation of visual properties of surface materials. It specifies their altering appearance due to varying illumination and viewing conditions. Corresponding huge BTF measurements require a mathematical representation allowing simultaneously extremal compression as well as high visual fidelity. We present a novel Markovia...

A gray-level image texture descriptors based on fractal dimension estimation is proposed in this work. The proposed method estimates the fractal dimension using probability (Voss) method. The descriptors are computed applying a multiscale transform to the fractal dimension curves of the texture image. The proposed texture descriptor method is evaluated in a classification task of well known ben...

Many objects have patterns that vary in appearance at different surface locations. We say that these are differences in materials, and we present a material-space approach for interactively designing such textures. At the heart of our approach is a new method to pre-calculate and use a 3D texture tile that is periodic in the spatial dimensions (s, t) and that also has a material axis along whic...

Reconstruction of archaeological finds from fragments, is a tedious task requiring many hours of work from the archaeologists and restoration personnel. In this paper we present a framework for the full reconstruction of the original objects using texture and surface design information on the sherd. The texture of a band outside the border of pieces is predicted by inpainting and texture synthe...

Three replicate trials were conducted to compare sensory descriptive profiles of cooked broiler breast fillets categorized by raw meat color lightness or CIE L* values. In each trial, 20 light, 20 dark, and 30 random fillets (42-d-old birds and deboned at 6 to 8 h postmortem) were obtained from a commercial processing plant. On return to the laboratory, CIE L* a* b* (medial side), pH, and weigh...

Image-based object modeling enables us to compose photorealistic images of modeled objects for various rendering conditions (viewpoints/light directions, etc.) However, it is very challenging to acquire a huge number of object images for all combinations of capturing parameters and to then handle the resulting huge data sets for the model. In this paper, we present a novel modeling method for a...

Texture analysis and synthesis has been studied extensively by many vision and graphics researchers. A very useful concept in texture analysis is texton or the basic element of a texture image. However, it remains unclear how to define a texton despite the fact that Julesz proposed the term ”texton” more than twenty years ago. In this talk, I will propose a two-level statistical model with text...

We present a novel technique for texture mapping on arbitrary surfaces with minimal distortions, by preserving the local and global structure of the texture. The recent introduction of the fast marching method on triangulated surfaces [9], made it possible to compute geodesic distances in O(~ n lg ~ n) where ~ n is the number of triangles that represent the surface. We use this method to design...
