Indoor Positioning and Indoor Navigation IPIN is a topic of research and industrial interest. Towards the direction of indoor positioning there are two main alternatives: absolute and relative. Absolute positioning requires infrastructure whereas relative positioning is based on dead reckoning and does not require any infrastructure. In this paper we perform a review of the last ten years of research for relative indoor positioning and navigation. We provide the four building blocks of an IPIN s...

We propose a simple and effective yet novel method designed for iOS smartphones that autonomously tracks its user's destinations and sparse trajectory. The smartphone application manages to do that 24/7 unobtrusively in the background and without consuming noticeable by the user battery energy. In this article we present the method and our highly encouraging early experimental results.

Abstract Virtual restoration of cultural heritage (CH) artefacts is an important task that aims to digitally recreate the original appearance of damaged items. In this paper, a method that can be used for virtual restoration of faces appearing in damaged Byzantine icons is presented. Given a damaged face, the complete three-dimensional (3D) geometry of the face is reconstructed using data from the non-damaged facial parts and the texture of the damaged areas is restored. A key aspect of the prop...

The identification of a bank note's value is a non-trivial task for the blind and the visually impaired. A popular approach adopted by many countries in order to facilitate the visually impaired, is the impression of a high-contrast, large-print region on their bank notes. Additionally, an approach used to facilitate the blind population is the impression of unique tactile marks on bank notes. However, even when tactile marks or different sizes (e.g. Euros) are used, blind and visually impaired ...

The use of 3D data in face image processing applications received increased attention during the recent years. However, the development of efficient 3D face processing applications (i.e face recognition) relies on the availability of appropriate 3D scanning technology that enables real time, accurate, non-invasive and low cost 3D data acquisition. 3D scanners currently available do not fulfill the necessary criteria. As an alternative to using 3D scanners, 3D face reconstruction techniques, capa...

3D imaging allows the detailed visualization of medical structures that can be very important in the process of treating patients. In this paper we describe a method for generating 3D models representing medical structures, using data derived from a single image showing a single cross-section of an object. The proposed method utilizes a 3D deformable model that is allowed to deform in order to approximate the shape of a medical structure as seen in a single cross-section, allowing in this way th...

Virtual restoration of Cultural Heritage (CH) artefacts is an important task that aims to re-create the original appearance of damaged items. In this paper we describe a method that can be used for virtual restoration of faces appearing in cultural heritage artefacts. Given a damaged face appearing in a 2D image we estimate the complete 3D shape of a face using data from the non-damaged face and we predict the texture of the damaged regions. As a result it is possible to generate a restored 3D m...

The use of 3D data in face image processing applications has received considerable attention during the last few years. A major issue for the implementation of 3D face processing systems is the accurate and real time acquisition of 3D faces using low cost equipment. In this paper we provide a survey of 3D reconstruction methods used for generating the 3D appearance of a face using either a single or multiple 2D images captured with ordinary equipment such as digital cameras and camcorders. In th...
