Recent developments in interferometric radar technique largely highlighted potentialities of radar interferometry for the generation of high resolution DEM (Digital Elevation Models). Nevertheless, the performances of this almost automatic process are strongly degraded for tortured reliefs and for vegetation areas. A research in progress with the CNES (Centre National d'Etudes Spatiales), CSSI ...

We present a novel information hiding process that couples geometrical modeling with automated 3D fabrication for creating hiddenappearance reliefs. Our relief surface produces a first grayscale appearance visible by simple direct illumination and a second grayscale appearance ensured to be visible when the relief is lit by a digital projector with a specifically designed pattern and from a par...

This paper presents a mobile Lidar system for efficiently and accurately capturing the 3D shape of the Bas-reliefs in Angkor Wat. The sensor system consists of two main components: 1) a panoramic camera and 2) a 2D 360-degree laser line scanner, which moves slowly on the rails parallel to the reliefs. In this paper, we first propose a new but simple method to accurately calibrate the panoramic ...

on the one hand, the vacant position of study about impact of achaemenid empire on eastern states is due to silence by classic authors in dealing with these lands; and on the other hand, it is reffered to shortage of archeological artifacts relating to achaemenids at the given region. in the present essay, by the aid of reminiscent works and economic and administrative evidences obtained from e...

Nowadays, the creation of methodologies and tools for facilitating the 3D reproduction of artworks and, contextually, to make their exploration possible and more meaningful for blind users is becoming increasingly relevant in society. Accordingly, the creation of integrated systems including both tactile media (e.g., bas-reliefs) and interfaces capable of providing the users with an experience ...

〈Summary〉 3D structure of proteins deeply relates to their functionality. It is wellknown that functions of proteins strongly appear in the bumpy parts of the molecular surfaces, and therefore geometric analysis of protein molecular surfaces is important. We propose a technique to extract geometric features of protein molecular surfaces, and a visual interface to effectively visualize the extra...

This overview on Sasanian stuccoes includes the Parthian sites hinting at a transmission of iconographies (i.e., Qaleh-I Zohak and Yazdgird), also with uncertain chronological attribution. On one hand, it underlines lack within Iranian plateau, other how majority was found in western territories. Noteworthy is examination illustrations some archaeological discoveries, i.e., Barz Qavela, Qela Go...
