By increasing the volume and complexity of datasets, Visual Data Mining (VDM), new visualization techniques evolved and new techniques released. However, some of these techniques performing well and cover all expectations; the others failed to save their positions. The main issue of such techniques is problem dependency. In this study, after a short description about necessity of Visual Data Mi...

Comprehending results from 3D CFD simulation is a difficult task. In this paper, we present a semantics-based approach to featurebased volume rendering of 3D flow data. We make use of interactive feature specification to acquire derived data about what is most interesting to the user. This process results in so-called degree-ofinterest (DOI) values, associated with the original data items. This...

segmentation and three‑dimensional (3d) visualization of teeth in dental computerized tomography (ct) images are of dentists’ requirements for both abnormalities diagnosis and the treatments such as dental implant and orthodontic planning. on the other hand, dental ct image segmentation is a difficult process because of the specific characteristics of the tooth’s structure. this paper presents ...

In this paper we describe the virtual reconstruction of a dismantled and dispersed piece of art: the Funerary Complex of Arrigo VII. To faithfully reconstruct the monument, all of the statues and elements of the mausoleum have been acquired in digital 3D format; then, with advanced computer graphics techniques, some of the accredited reconstructing hypothesis have been assembled and evaluated.

This paper presents methods for 3D modeling of railway environments from airborne laser scanning (ALS) and mobile laser scanning (MLS). Conventionally, aerial data such as ALS and aerial images were utilized for 3D model reconstruction. However, 3D model reconstruction only from aerial-view datasets can not meet the requirement of advanced visualization (e.g., walk-through visualization). In th...

The present study is embedded within the Virtual Sky project, currently undergoing at the EUROCONTROL R&D Center, which aims to investigate the potentiality of a 3D stereoscopic environment for ATC. This paper describes the design of visualizations and interactions within a multidisciplinary framework for the empirical analysis of the applicability of three-dimensional (3D) stereoscopic visuali...

Real-time 3D ultrasound (3DUS) imaging offers improved spatial orientation information relative to 2D ultrasound. However, in order to improve its efficacy in guiding minimally invasive intra-cardiac procedures where realtime visual feedback of an instrument tip location is crucial, 3DUS volume visualization alone is inadequate. This paper presents a set of enhanced visualization functionalitie...

Urban environments present unique challenges to interactive visualization systems, because of the huge complexity of the geometrical data and the widely varying visibility conditions. This paper introduces a new framework for real-time visualisation of such urban scenes. The central concept is that of a dynamic segmentation of the dataset, into a local three-dimensional model and a set of impos...

This is the preprint version of our paper on ICONIP2015. The proposed platform supports the integrated VRGIS functions including 3D spatial analysis functions, 3D visualization for spatial process and serves for 3D globe and digital city. The 3D analysis and visualization of the concerned city massive information are conducted in the platform. The amount of information that can be visualized wi...

The article presents a general concept of the organization of pseudo 3D visualization of graphics and video content for 3D visualization systems. The steps of algorithms for solving the problem of synthesis of 3D stereo images based on 2D images are introduced. The features of synthesis organization of standard format of 3D stereo frame are presented. Moreover, the performed experimental simula...
