  1. 6. Local spatio-temporal image features for motion interpretation

    Författare :Ivan Laptev; KTH; []
    Nyckelord :computer vision; motion; recognition; scale-space;

    Sammanfattning : Visual motion carries information about the dynamics of ascene. Automatic interpretation of this information isimportant when designing computer systems forvisualnavigation, surveillance, human-computer interaction, browsingof video databases and other growing applications.

  3. 7. Bring Your Body into Action : Body Gesture Detection, Tracking, and Analysis for Natural Interaction

    Författare :Farid Abedan Kondori; Li Liu; Juyang Weng; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Human Well-Being; Bodily Interaction; Natural Interaction; Human Motion Analysis; Active Motion Estimation; Direct Motion Estimation; Head Pose Estimation; Hand Pose Estimation.; signalbehandling; Signal Processing; datoriserad bildanalys; Computerized Image Analysis;

    Sammanfattning : Due to the large influx of computers in our daily lives, human-computer interaction has become crucially important. For a long time, focusing on what users need has been critical for designing interaction methods. LÄS MER

  4. 8. The perception of actions and interactions : And the importance of context

    Författare :Joshua Juvrud; Gustaf Gredebäck; Denis Mareschal; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; action understanding; action perception; motion; perception; context; environment; eye-tracking; pupil dilation; Psychology; Psykologi;

    Sammanfattning : The perception of actions and interactions is a dynamic process linked with perceptual processes, the internal and external states of the individual, prior experiences, and the immediate environment. Given these differential contexts, it is very likely there are differences in how infants perceive, interpret, and respond to actions. LÄS MER

  5. 9. Models and Algorithms - with applications to vehicle tracking and frequency estimation

    Författare :Joakim Gunnarsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; motion models; subspace methods; radar detections; Automotive; F-ESPRIT.; vehicle tracking; frequency estimation;

    Sammanfattning : This thesis considers two different research problems; one concerned with the issue of tracking vehicles and one related to estimating frequencies in harmonic signals. The vehicle-tracking problem is addressed from the perspective of an automotive-safety application, which seeks to monitor the course of surrounding road users with the objective to make decisions regarding if, how and when to intervene.

  7. 10. Multi-scale feature tracking and motion estimation

    Författare :Lars Bretzner; KTH; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : This thesis studies the problems of feature tracking and motion estimation and presents an application of these concepts to human-computer interaction. The presentation is divided into three parts. The first part addresses feature tracking in a multi-scale context. LÄS MER
