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 ...

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...

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...

Bas-reliefs of scenes from the epics Rāmāyaṇa and Mahābhārata are extremely common in temples all over India, but depictions a Sanskrit drama (mahānāṭaka) places worship virtually unheard of. A few bas-reliefs at Lokeśvara Temple Trailokyeśvara Paṭṭadakal depict centring around female figure, who is arguably Śakuntalā. The story Śakuntalā first mentioned was subsequently dramatised by Kālidāsa ...

Bi-Laplacian High order differentials Construction Construction and restoration a b c d Self intersection of the scene parts Undesired scene deformations Dents around attenuation points 1 Different Solutions In order to obtain the final relief geometry, we use two fitting steps, construction and restoration, instead of using one step fitting methods such as bi-Laplacian, higher order Laplacians...
