An Energy Efficient Localization Strategy for Outdoor Objects based on Intelligent Light-Intensity Sampling
(Lecture Notes in Computer Science;6406, Journal article; Peer reviewed, 2010-10-05)A simple and low cost strategy for implementing pervasive objects that identify and track their own geographical location is proposed. The strategy, which is not reliant on any GIS infrastructure such as GPS, is realized ... -
A Simple Content-based Strategy for Estimating the Geographical Location of a Webcam
(Lecture Notes in Computer Science = Lecture notes in artificial intelligence;6297, Journal article; Peer reviewed, 2010)This study proposes a strategy for determining the approximate geographical location of a webcam based on a sequence of images taken at regular intervals. For a time-stamped image sequence spanning 24 hours the approximate ... -
Towards calibration-free geo-localization of stationary outdoor webcams
(Norsk Informatikkonferanse; 2010, Chapter; Peer reviewed, 2010)This study proposes two strategies for determining the approximate geographical location of outdoor webcams based on time-series comprising regularly sampled images. The strategies require an accurate account of universal ... -
Where was that photo taken? : deriving geographical information from image collections based on temporal exposure attributes
(Multimedia Systems;16 (4-5), Journal article; Peer reviewed, 2010-05-14)This paper demonstrates a novel strategy for inferring approximate geographical information from the exposure information and temporal patterns of outdoor images in image collections. Image exposure is reliant on light ...
