This paper introduces the 3D Measurement and Virtual Reconstruction of Ancient Lost Worlds of Europe system (3D MURALE). It consists of a set of tools for recording, reconstructing, encoding, visualising and database searching/querying that operate on buildings, building parts, statues, statue parts, pottery, stratigraphy, terrain geometry and texture and(More)
Textures often result from complicated surface geome-tries. We propose a method that extracts such geometry from raw BTF data. Exploiting the huge amount of input data, only a few and rather weak assumptions about reflectance and geometry suffice. A key element of our approach are viewpoint robustness of reflectance features. We propose a few and compare(More)
Mapping textured images on smoothly approximated surfaces is often used to conceal the loss of their real, fine-grained relief. A limitation of mapping a fixed texture in such cases is that it will only be correct for one viewing and one illumination direction. The presence of geometric surface details causes changes that simple foreshortening and global(More)
Many textures require complex models to describe their intricate structures. Their modeling can be simplified if they are considered composites of simpler subtextures. After an initial, unsupervised segmentation of the composite texture into the subtextures, it can be described at two levels. One is a label map texture, which captures the layout of the(More)
Increasingly, models of the world are directly built from images. The paper discusses a number of recent developments that try to push the enveloppe of what image-based modeling can achieve. In particular, the analysis of 3D surface deformations is discussed for face animation, the extraction of matches under wide baseline conditions for 3D scene(More)

The methods for the extraction of the main texture properties and for the subsequent texture synthesis are proposed based on the formal definitions of the essential statistical properties and the notion of texture in terms of pairwise and singleton signal interactions. The iterative synthesis procedure is a successive approximation in the space of the(More)
