Introduction. High-resolution topographic information is important in different applications for the study of planetary surfaces: their evolution, state, and properties. The most precise topographic data are obtained through direct measurements with different altimeters on board of spacecrafts (e.g., [1]). Indirect techniques for surface height estimates involve photogrammetry (e.g., [2]), phot...

The patterning of an acrylamide-based photopolymer surface by holographic recording is studied. The patterns are induced by light alone and no post-processing is required. Periodic surface modulation is observed in addition to a volume phase grating. An investigation has been carried out using white light interferometry into the dependence of the amplitude of the photo induced surface relief mo...

Surface relief formed by nanoimprinting and etching into a thermally grown SiO2 layer on Si was used to position the initial nuclei formed by chemically vapor deposited Si and Ge. By controlling the deposition conditions, the surface diffusion length was adjusted to be comparable to or larger than the spacing between features, thus favoring nucleation adjacent to steps, rather than random nucle...

Relief representation is a difficult problem. The surface of the Earth cannot be defined by a physical or mathematical representation but can be approximated by digital elevation models (DEM), triangular irregular networks (TIN), and contour lines. Each representation carries approximation errors. A DEM introduces the greatest errors because we assume that the surface of the Earth can be approx...

Image intensity variations can result from several di erent object surface e ects, including shading from 3-dimensional relief of the object, or paint on the surface itself. An essential problem in vision, which people solve naturally, is to attribute the proper physical cause, e.g. surface relief or paint, to an observed image. We addressed this problem with an approach combining psychophysica...

We have discovered that a novel chiral structured surface relief (termed 'conch'-shaped surface relief) with a height of over 1 μm can be formed in an azo-polymer film merely by employing circularly polarized optical vortex irradiation with a total angular momentum of j = ±2. The temporal evolution of the conch-shaped surface relief in the azo-polymer film was also observed. The results provide...

Image intensity variations can result from several different object surface effects, including shading from 3-dimensional relief of the object, or paint on the surface itself. An essential problem in vision , which people solve naturally, is to attribute the proper physical cause, e.g. surface relief or paint, to an observed image. We addressed this problem with an approach combining psychophys...

Segmentation of geometric reliefs from a textured background has various applications in reverse engineering. We consider two approaches to solve this problem. The first classifies parts of a surface mesh as relief or background, and then uses a snake which moves inwards towards the desired relief boundary, which is coarsely located using an energy based on the classification. The second approa...
