  1. 6. Sampling and predicting geographic areas using participatory sensing

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Wei Wang; [2015]
    Keywords : ;

    Abstract : Participatory sensing is the concept that people contribute information they retrieved independently from the environment using sensors to build a whole body of knowledge. With the popularity of mobile devices, such as smart phones, which have multiple sensors and wireless interfaces, "participatory sensing" has become feasible in a large-scale. READ MORE

  3. 7. Exploring Spatio-Temporal Patterns of Volunteered Geographic Information : A Case Study on Flickr Data of Sweden

    University essay from Avdelningen för Industriell utveckling, IT och Samhällsbyggnad

    Author : Yufan Miao; [2013]
    Keywords : Big Data; VGI; Flickr; Delaunay Triangulation; Power Law; Scaling Analysis; Spatio-Temporal Pattern;

    Abstract : This thesis aims to seek interesting patterns from massive amounts of Flickr data in Sweden with pro- posed new clustering strategies. The aim can be further divided into three objectives. The first one is to acquire large amount of timestamped geolocation data from Flickr servers. READ MORE

  4. 8. Brain Tumor Volume Calculation : Segmentation and Visualization Using MR Images

    University essay from Biomedicinsk instrumentteknik; Tekniska högskolan

    Author : Fabian Balsiger; [2012]
    Keywords : ;

    Abstract : Background: Glioblastomas are highly aggressive and malignant brain tumors which are difficult to resect totally. The surgical extent of resection constitutes a key role due to its direct influence on the patient’s survival time. READ MORE

  5. 9. Volume Estimation of Airbags: A Visual Hull Approach

    University essay from Institutionen för systemteknik

    Author : Manne Anliot; [2005]
    Keywords : Bildanalys; Airbag Reconstruction; Volume Estimation; Visual Hull; Pinhole Camera Model; Simulated Annealing; Delaunay Triangulation; Best-Camera-Pose; Bildanalys;

    Abstract : This thesis presents a complete and fully automatic method for estimating the volume of an airbag, through all stages of its inflation, with multiple synchronized high-speed cameras. Using recorded contours of the inflating airbag, its visual hull is reconstructed with a novel method: The intersections of all back-projected contours are first identified with an accelerated epipolar algorithm.
