This paper presents a system to create a spatiotemporal attractiveness GIS layer for mountainous areas brought about by the implementation of novel image processing and pattern matching algorithms. We utilize the freely available Digital Terrain Model of the planet provided by NASA [1] to generate a three-dimensional synthetic model around a viewer‟s(More)
Personalisation of large scale athletic events requires camera-specific annotations to provide for reasoning about incidents being best viewed by specific cameras. This needs an automatic system for annotating athletes on the video streams, to be achieved by the use of person trackers. In this paper we present a novel approach towards combining scene(More)
This paper presents a model-based photo registration system for the creation and visualization of environmental content. We utilize freely available Digital Terrain Models of the planet, such as those provided by NASA, to generate a three-dimensional synthetic model around a viewer’s location. Using an array of image processing algorithms we then align(More)
This paper presents a technology capable of enabling the creation of a diffuse, calibrated vision-sensor network from the wealth of socially generated geo-referenced imagery, freely available on the Internet. Through the implementation of an accurate image registration system, based on image processing, terrain modelling and subsequent correlation, we will(More)
The <sc>MEMORI</sc> system automatically detects and recognizes rescaled and/or rotated versions of objects from a database within digital color images with cluttered background. This paper describes the system's architecture and the methods implemented within, and its use as a tool for the automatic annotation and browsing of digital images of web(More)
Augmented Reality (AR) is a technology which permits us to mix virtual and real scenes in both time and space [1, Ch. 1], opening up the possibility to inject virtual information into a scene viewed through a portable device. AR can be useful in many applicative domains [1], such as in touristic guidance (e.g., providing detailed descriptions of monuments),(More)
The demand for efficient methods for extracting knowledge from multimedia content has led to a growing research community investigating the convergence of multimedia and knowledge technologies. In this paper we describe a methodology for extracting multimedia information from product catalogues empowered by the synergetic use and extension of a domain(More)
The acquisition of natural scenes is not restricted to orbiting or airborne platforms. The near ubiquitous and profuse distribution of ground-level, high-quality imaging devices, i.e., digital cameras and smartphones, is offering a free socially generated resource, which could be exploited for geo-sensing. Such socially distributed sensing can not only be(More)
