Yong Khoo This paper presents a new method for 3D shape reconstruction based on two existing methods. A 3D reconstruction from a single photograph is introduced by both papers: the first one written by Huang et al.1 use a photograph and a set of existing 3D model to generate the 3D object in the photograph, while the second one written by Xu et al.2 use a photograph and a selected similar model...

conclusion vr reconstruction for both single-direction images and sushi using dti25 raw data provides excellent 3d displays of the peripheral nerves in the wrist region. sushi post-processing is a useful denoising tool because it automatically reduces the majority of isotropic object noise. results single-direction vr reconstruction clearly showed the nerves for both dti6 and dti25 but with obv...

abtract background: in nuclear medicine, phantoms are mainly used to evaluate the overall performance of the imaging systems and practically there is no phantom exclusively designed for the evaluation of the software performance.  in this study the hoffman brain phantom was used for quantitative evaluation of reconstruction techniques. the phantom is modified to acquire tomographic and planar i...

introduction 3d reconstruction of an object from its 2d cross-sections (slices) has many applications in different fields of sciences such as medical physics and biomedical engineering. in order to perform 3d reconstruction, at first, desired boundaries at each slice are detected and then using a correspondence between points of successive slices surface of desired object is reconstructed. mate...

In computer vision we often estimate a 3D model of an object, and its uncertainty, up to an unknown scale factor. This unknown scale factor means that we cannot directly infer positions and lengths on the model, nor their uncertainties. In order to make quantitative distance measurements on this model, we must obtain the unknown scale factor. However, how we determine the scale factor will affe...

Texturing gives a new quality to a 3D model making it more similar to real object and more adequate for human perception and understanding. Recent progress in means for spatial data acquisition and in 3D reconstruction techniques creates a background for metric 3D models generation, which could be successfully used instead of a real object for purposes of various investigations dealing with geo...

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...
