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)
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)
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)
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)
In building 3D site models for visualization and virtual walkthrough, most emphasis so far has been on creating the 3D shape models. Less emphasis has been on creating realistic textures, e.g. to simulate building materials or vegetation. Nevertheless, the appearance of object and landscape models will depend at least as much on their textures, as on the(More)
