The recent advances in large-scale scene modeling have enabled the automatic 3D reconstruction of landmark sites from crowdsourced photo collections. Here, we address the challenge of leveraging crowdsourced video collections to identify connecting visual observations that enable the alignment and subsequent aggregation, of disjoint 3D models. We denote these connecting image sequences as video...

This issue discusses methods to extract three-dimensional (3D) models from plain images. In particular, the 3D information is obtained from images for which the camera parameters are unknown. The principles underlying such uncalibrated structure-from-motion methods are outlined. First, a short review of 3D acquisition technologies puts such methods in a wider context and highlights their import...

Objective: The aim of this study was to evaluate the influences of reconstruction and attenuation correction on the differences in the radioactivity distributions in 123I brain SPECT obtained by the hybrid SPECT/CT device. Methods: We used the 3-dimensional (3D) brain phantom, which imitates the precise structure of gray mater, white matter and bone regions. It was filled with 123I solution (20...

A software for processing sets of full-color images of biological tissue histological sections is developed. We used histological sections obtained by the method of high-precision layer-by-layer grinding of frozen biological tissues. The software allows restoring the image of the tissue for an arbitrary cross-section of the tissue sample. Thus, our method is designed to create a full-color 3D r...

In recent years the Vision community has shown interest in processing images and video for use by the entertainment industries. Typical applications include 3D reconstruction of models, and rendering graphics models into video. This paper broadly aligns with that trend, but differs in that we process video to emphasise motion in Cartoon-like styles, in which moving objects deform in defiance of...

The paper presents a system for 3D reconstruction from multiple uncalibrated unorganized images. A number of alternative reconstruction techniques can be combined together by the means of a simple language. A complete reconstruction procedure is defined by a program in this language. Such an approach allows to choose a suitable reconstruction method for the situation at hand and thus obtain use...
