This paper describes an approach to reconstruct the complete history of a 3-d scene over time from imagery. The proposed approach avoids rebuilding 3-d models of the scene at each time instant. Instead, the approach employs an initial 3-d model which is continuously updated with changes in the environment to form a full 4-d representation. This updating scheme is enabled by a novel algorithm th...

One of the law-like regularities of psychological science is that of developmental progression – an increase in sensorimotor, cognitive, and social functioning from childhood to adulthood. Here we report a rare violation of this law – a developmental reversal in attention. In Experiment 1, 4to-5-year-olds (N= 34) and adults (N = 35) performed a change detection task that included externally cue...

The purpose of this paper is to develop the GIS educational environment in training program using open-source GIS software. First, we have verified the substitutability of laboratory exercise materials at our university from commercial GIS to open-source GIS software. Next, we grasp the improvement situation of the free spatial data that are opened to the public by the government and present th...

This paper deals with a Speed Limit Assistant (SLA) performing the fusion of a Geographic Information System (GIS) and a vision system. The present strategy is based on multi-level data fusion using Evidence Theory. In a first step, the GIS reliability is estimated through GIS criteria related to the positioning, the localization and the digital map resolution. Contextual criteria also extracte...

Geographic information systems (GIS) technology and methods have transformed decision-making in society by bringing geographic analysis to the desktop computer. Although some educators consider GIS to a promising means for implementing reform, it has been adopted by less than 2% of American high schools. The reasons behind the interest in GIS, its slow implementation, and its effectiveness in t...

In the mid-1990s, several critical texts raised concerns about the social, political, and epistemological implications of GIS. Subsequent responses to these critiques have fundamentally altered the technological, political, and intellectual practices of GIScience. Participatory GIS, for instance, has intervened in multiple ways to try to ameliorate uneven access to GIS and digital spatial data ...

The combination of "voice technology" and "Mobile GIS", has greatly improved the intelligent degree of mobile GIS. Recently, significant attention in the field of scientific research is turning to how to realize quick conversion between natural language and GIS commands. However, the current study mostly concentrates on rules of conversion between natural language sentences and GIS commands fro...

The paradigm of geographic information systems (GISs) is shifting from a closed, centralized GIS architecture, to an open, distributed geographic information services (GIServices) framework. With advances in computer networking and wireless communication technology, GIS is moving toward an integration of GIServices and spatial analysis functions via the internet and wireless communication. Wire...

Mapping of diseases has, since John Snow produced his famous cholera maps of London in 1854, been recognised as an essential tool in public health. A Geographical Information System (GIS) is more than mapping diseases: it manages, analyses and presents data that are linked to geographical locations. GIS enables creation of maps and can present data on national and regional level, but also on ve...
