  1. 1. Improving fingerprint biometrics by local symmetry and fusion

    Författare :Hartwig Fronthaler; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Alignment; Matching; Minutiae Extraction; Image Restoration; Multi-expert Fusion; Biometrics; Symmetry Features; Structure Tensor; Quality Assessment; Fingerprint Recognition; Image Pyramid; Enhancement; Rotational Symmetry; Cascaded Fusion; Monomodal Fusion; Fingerprint;

    Sammanfattning : Fingerprint recognition and biometrics in general have been significantly gaining attention within the last years, not least due to the biometric passport that has been introduced all over Europe and the American immigration management system US-VISIT. The tasks of fingerprint recognition can be broken down to smaller entities, i.e. LÄS MER

  3. 2. Interest Curves : Concept, Evaluation, Implementation and Applications

    Författare :Bo Li; Ulrik Söderström; Haibo Li; Björn Kruse; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; scale-invariance; edge; corner; curve; line; matching; object detection; signalbehandling; Signal Processing;

    Sammanfattning : Image features play important roles in a wide range of computer vision applications, such as image registration, 3D reconstruction, object detection and video understanding. These image features include edges, contours, corners, regions, lines, curves, interest points, etc. LÄS MER

  4. 3. Valence-Level Dependent Presentation-Order Effects in Preference Judgments

    Författare :Mats P. Englund; Åke Hellström; William M. Petrusic; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Preference judgment; order effects; stimulus valence; sensation weighting; feature matching; comparison direction; Psychology; Psykologi; Psychology; psykologi;

    Sammanfattning : Reversal of the stimulus-presentation order often affects the outcome in paired stimulus comparison. Psychophysicists have found that the size and direction of the order effects depend on the compared stimuli’s magnitudes, but this magnitude dependence does not seem to have been recognized previously in cognitive research on preference judgment.

  5. 4. Efficient Map Matching and Discovery of Frequent and Dominant Movement Patterns in GPS Trajectory Data

    Författare :Can Yang; Yifang Ban; Gyözö Gidofalvi; Xiaoliang Ma; Mirco Nanni; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; map matching; contiguous sequential pattern mining; contiguous sequential pattern comparison; movement pattern detection; Kartmatchning; sammanhängande sekventiellt mönster utvinning; sammanhängande sekventiellt mönster jämförelse; rörelsemönster detektering; Geoinformatics; Geoinformatik;

    Sammanfattning : The wide deployment of Global Positioning System (GPS) sensors for movement data collection has enabled a wide range of applications in transportation and urban planning. Frequent and dominant movement patterns embedded in GPS trajectory data provide valuable knowledge including the spatial and temporal distribution of frequent routes selected by the tracked objects and the regular movement behavior in certain regions.

  7. 5. Feature-Based Image Processing for Rendering, Compression, and Visual Search

    Författare :Haopeng Li; Markus Flierl; Peter Eisert; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Visual communication, vivid, meaningful, and creative, permits a way to express information visually. The communication media, by images, graphs and videos, passes informative color and shape to human perception sensors. LÄS MER
