User mobility has given rise to a variety of Web applications, in which the global positioning system (GPS) plays many important roles in bridging between these applications and end users. As a kind of human behavior, transportation modes, such as walking and driving, can provide pervasive computing systems with more ...
Keywords: GPS trajectory, GeoLife, Spatial data mining, transportation modes, ubiquitous computing, understanding user behavior, user mobility

January 2009 PSIVT '09: Proceedings of the 3rd Pacific Rim Symposium on Advances in Image and Video Technology
Publisher: Springer-Verlag
Citation Count: 1

In this paper, a novel algorithm is introduced to group contours from clutter images by integrating high-level information (prior of part segments) and low-level information (paths of segmentations of clutter images). The partial shape similarity between these two levels of information is embedded into the particle filter framework, an effective ...
Keywords: partial shape similarity, particle filter, Normalized Cuts, Contour grouping

The pervasiveness of location-acquisition technologies (GPS, GSM networks, etc.) enable people to conveniently log the location histories they visited with spatio-temporal data. The increasing availability of large amounts of spatio-temporal data pertaining to an individual's trajectories has given rise to a variety of geographic information systems, and also brings us ...
Keywords: GPS logs, user similarity, similar sequence matching, spatio-temporal data mining

Both recognizing human behavior and understanding a user's mobility from sensor data are critical issues in ubiquitous computing systems. As a kind of user behavior, the transportation modes, such as walking, driving, etc., that a user takes, can enrich the user's mobility with informative knowledge and provide pervasive computing systems ...
Keywords: GeoLife, GPS, infer transportation mode, machine learning, recognize human behavior
