  1. 1. Lip-motion and speech biometrics in person recognition

    Författare :Maycel Isaac Faraj; Högskolan i Halmstad; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Audio-visual recognition; biometrics; Biometric recognition; Speaker verification; Speaker authentication; Person identification; Lip movements; Motion; Structure tensor; Orientation; Optical flow; Hidden Markov Model; Gaussian Markov Model; Lip-motion; Image analysis; Bildanalys;

    Sammanfattning : Biometric identification techniques are frequently used to improve security, e.g. in financial transactions, computer networks and secure critical locations. The purpose of biometric authentication systems is to verify an individual by her biological characteristics including those generating characterisitic behaviour. LÄS MER

  3. 2. 3D Gesture Recognition and Tracking for Next Generation of Smart Devices : Theories, Concepts, and Implementations

    Författare :Shahrouz Yousefi; Haibo Li; Touradj Ebrahimi; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; 3D gestural interaction; gesture recognition; gesture tracking; 3D visualization; 3D motion analysis; augmented environments; Media Technology; Medieteknik;

    Sammanfattning : The rapid development of mobile devices during the recent decade has been greatly driven by interaction and visualization technologies. Although touchscreens have signicantly enhanced the interaction technology, it is predictable that with the future mobile devices, e.g. LÄS MER

  4. 3. Video based analysis and visualization of human action

    Författare :Martin Eriksson; Stefan Carlsson; Ian Reid; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Människa-dator-interaktion; Motion analysis; Visualization; Human tracking; virtual coach; Människa-dator-interaktion; Information technology; Informationsteknologi;

    Sammanfattning : Analyzing human motion is important in a number of ways. An athlete constantly needs to evaluate minute details about his or her motion pattern. In physical rehabilitation, the doctor needs to evaluate how well a patient is rehabilitating from injuries. Some systems are being developed in order to identify people only based on their gait.

  5. 4. Model-based Methods in Motion Capture

    Författare :Kjartan Halvorsen; Antonie J. van den Bogert; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Systems engineering; Systemteknik; Systemanalys; Systems Analysis;

    Sammanfattning : This thesis concerns the use of kinematic models and shape models to solve the problem of estimating the motion of articulated objects from image data. The data considered in the first part of the thesis are trajectories of 3D feature points (markers). In the second part, image sequences are considered. LÄS MER

  7. 5. Biomechanical assessment of head and neck movements in neck pain using 3D movement analysis

    Författare :Helena Grip; Gertjan Ettema; Umeå universitet; []
    Nyckelord :movement analysis; kinematics; helical axis; neck pain; whiplash; cervical spine; pattern classification; motor control; head-eye co-ordination; head movement; biomedicinsk strålningsvetenskap; Biomedical Radiation Science;

    Sammanfattning : Three-dimensional movement analysis was used to evaluate head and neck movement in patients with neck pain and matched controls. The aims were to further develop biomechanical models of head and neck kinematics, to investigate differences between subjects with non-specific neck pain and whiplash associated disorders (WAD), and to evaluate the potential of objective movement analysis as a decision support during diagnosis and follow-up of patients with neck pain.
