Gorte, B.G.H. (author), Zlatanova, S. (author)The paper presents a very straightforward and effective algorithm to convert a space partitioning, made up of polyhedral objects, into a 3D block of voxels, which is fully occupied, i.e. in which every voxel has a value. In addition to walls, floors, etc. there are 'air' voxels, which in turn may be distinguished as indoor and outdoor air....journal article 2016

Sirmacek, B. (author), Shen, Y. (author), Lindenbergh, R.C. (author), Zlatanova, S. (author), Diakite, A.A. (author)We present a comparison of point cloud generation and quality of data acquired by Zebedee (Zeb1) and Leica C10 devices which are used in the same building interior. Both sensor devices come with different practical and technical advantages. As it could be expected, these advantages come with some drawbacks. Therefore, depending on the...journal article 2016

Zlatanova, S. (author)Topological relations between spatial objects have been widely recognized, implemented, and used in GIS. They provide a notion of the general structure and the interactions of spatial objects. Topology avoids dealing with geometry by introducing topological primitives, namely, boundary, interior, and exterior.book chapter 2016

Diakite, A.A. (author), Zlatanova, S. (author)During the last two decades, the third dimension took an important place in the heart of every multimedia. While the 3D technologies mainly used to be tools and subject for researchers, they are becoming commercially available to large public. To make it even more accessible, the Project Tango, leaded by Google, integrates in a simple Android...journal article 2016

Zlatanova, S. (author), Sithole, George (author)Over the last decade, harnessing the commercial potential of smart mobile devices in indoor environments has spurred interest in indoor mapping and navigation. Users experience indoor environments differently. For this reason navigational models have to be designed to adapt to a user’s personality, and to reflect as many cognitive maps as...journal article 2016

Zhou, Yan (author), Zlatanova, S. (author), Wang, Zhe (author), Zhang, Yeting (author), Liu, L. (author)Video surveillance systems are increasingly used for a variety of 3D indoor applications. We can analyse human behaviour, discover and avoid crowded areas, monitor human traffic and so forth. In this paper we concentrate on use of surveillance cameras to track and reconstruct the path a person has followed. For the purpose we integrated video...journal article 2016

Zlatanova, S. (author), Nourian Ghadikolaee, P. (author), Goncalves, R. (author), Vo, A.V. (author)Three-dimensional (3D) raster are simple representations, which have long been used for modelling continuous phenomena such as geological and medical objects. However, they can result in large data sets when high resolution is used, which poses challenges to algorithms for vector-to-raster conversion and data storage. This paper presents a...conference paper 2016

Zlatanova, S. (author), Isikdag, Umit (author)Indoor environments are often referred as to enclosed spaces. However, the general definition of space can already indicate that a space can be bounded. Wordnet (http://wordnet.priceton.edu) defines space as “an empty areas usually bounded in some way between things.”book chapter 2016

Wang, Z. (author), Zlatanova, S. (author), Steenbruggen, John (author)Traffic incidents can result in different kinds of hazards (e.g., plumes) that influence the status of road networks, therefore there is a great need for incident management in the presence of the hazards. When incidents occur, the created hazards not only affect the normal road users (make them detour or blocked), but also influence the...journal article 2016
