Advances in 3D scanning technology allow us to create realistic virtual avatars from full body 3D scan data. However, negative reactions to some realistic computer generated humans suggest that this approach might not always provide the most appealing results. Using styles derived from existing popular character designs, we present a novel automatic stylization technique for body shape and colo...

Files of 3D models are often large and time-consuming to download. Most 3D viewers need the entire file to display a 3D model even when the user is interested only in a part of or a low-resolution version of the model. Therefore, progressive coding of 3D models is desired. However, existing work studies either the progressive coding of the geometry only, or progressive coding of the texture onl...

In this paper, we propose a novel method for generating 3D line segment based model from an image sequence taken with a RGB-D camera. Constructing 3D geometrical representation by 3D model is essential for model based camera pose estimation that can be performed by corresponding 2D features in images with 3D features of the captured scene. While point features are mostly used as such features f...

A process is presented for the creation of immersive highdynamic range 3D models from a pair of spherical images. The concept of applying a spherical Delauney triangulation to 3D model creation is introduced and a complete texturing solution is given.

In this paper, a novel technique combining intensity and range data is presented. Passive (intensity based) and active (range based) techniques used for 3D reconstruction have their limitations and separately, none of these techniques can solve all the problems inherent to the modelling of real environments. Our technique aims to demonstrate how both intensity and range data can be registered a...

A number of software solutions for reconstructing 3D models from multi-view image sets have been released in recent years. Based on an unordered collection of photographs, most of these solutions extract 3D models using structure-from-motion (SFM) algorithms. In this work, we compare the resulting 3D models qualitatively and quantitatively. To achieve these objectives, we have developed differe...

  Background & Aim: Nowadays, radiosensitive polymer gels are used as a reliable dosimetry tool for verification of 3D dose distributions. Polymer gel dosimeters consist of an aqueous mixture of monomers and a gelling agent, which after irradiation, 3D dose distribution is acquired by using imaging techniques. The aim of this study is to evaluate the application and capability of normoxic polym...

Background: 3DCRT (three-dimensional conformal radiotherapy) and IMRT (intensity-modulated radiotherapy) has provided us with tools to delineate the radiation dose distribution of tumor targets. However, the precision of radiation can be compromised by respiratory motion, which usually limits the geometric and dosimetric accuracy of radiotherapy. The purpose of this study is to evaluate the imp...

​During the recent years, the need arises for indoor navigation systems for guidance of a client in natural hazards and fire, due to the fact that human settlements have been complicating. This research paper aims to design and implement a visual indoor navigation web application. The designed system processes CityGML data model automatically and then, extracts semantic, topologic and geometric...

Research on pain experienced after Spinal Cord Injury (SCI) has revealed that not only are there several types of pain present in the same individual with this kind of trauma, but also that people who suffer such an injury can describe the characteristics of the same type of pain in different ways. Making it possible, therefore, to more precisely describe pain experience could prove to be vital...
