We propose a system enabling users to capture the data needed to construct maps of building interiors, complemented by a smartphone-based pedestrian navigation application utilizing these maps. For this purpose, the user captures photographs of evacuation plans which are processed by the system using a suitable image processing pipeline. As a result, a coarse floor map is available, consisting ...

The availability of Web 2.0 technologies has made it easy for information users to express their own opinions and access other people’s opinions on the Web. We are interested in understanding how opinions expressed in one way by one group compare to opinions expressed in another way by another group, especially in a different language. We have done reasonably well at finding opinionated English...

Sixty-four subjects participated in an olfactory priming experiment comprising separate study and test phases. Priming was measured within the olfactory modality (intramodal condition) and from the visual modality to the olfactory modality (intermodal condition). In the study phase of the intramodal condition, subjects were exposed twice to a series of odours: once performing a semantic orienta...

EEG event-related potentials (ERPs) and fMRI blood oxygenation level dependent (BOLD) new item contrasts were employed in six experiments to investigate the neural correlates of retrieval orientations cognitive states or ‘sets’ that align cue processing with the demands of a particular retrieval goal. It is proposed that the neural correlates of different retrieval orientations can be investiga...

Existing indoor navigation approaches such as navigation based on 2D geometries and pre-defined routing remain insufficient for many applications such as emergency response, delivery, utility maintenance, facility management and so on. The insufficiencies caused by existing navigation approaches can be overcome by using the advanced geometric and semantic information included in intelligent bui...

The experiment reported here investigates the perception of orientation of color photographic images. A collection of 1000 images (mix of professional photos and consumer snapshots) was used in this study. Each image was examined by at least five observers and shown at varying resolutions. At each resolution, observers were asked to indicate the image orientation, the level of confidence, and t...

In service-orientation, the notion of service is studied from different point of views. On the one hand, several approaches have been proposing services that are able to adapt themselves according to the context in which they are used. On the other hand, some researches have been proposing to consider user intentions when proposing business services. We believe that these two views are compleme...

a r t i c l e i n f o Keywords: Human upper body orientation Partial least squares Multi-level HOG-LBP Random Forest classifier UKF tracker This paper deals with the problem of estimating the human upper body orientation. We propose a framework which integrates estimation of the human upper body orientation and the human movements. Our human orientation estimator utilizes a novel approach which...
