  1. 1. Automatic object detection and tracking for eye-tracking analysis

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för systemteknik

    Författare :Liv Cederin; Ulrika Bremberg; [2023]
    Nyckelord :Computer Vision; Object Detection; Object Tracking; Eye-Tracking; Annotation; Deblurring; Deep Learning; Motion Blur;

    Sammanfattning : In recent years, eye-tracking technology has gained considerable attention, facilitating analysis of gaze behavior and human visual attention. However, eye-tracking analysis often requires manual annotation on the objects being gazed upon, making quantitative data analysis a difficult and time-consuming process. LÄS MER

  3. 2. Using pose estimation to support video annotation for linguistic use : Semi-automatic tooling to aid researchers

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Gustav Gerholm; [2022]
    Nyckelord :MINT project; pose estimation; video annotating; HyperPose; 3D-distance approximation; MINT-projektet; poseuppskattning; videoannotering; HyperPose; uppskattning av 3d-sträcka;

    Sammanfattning : Video annotating is a lengthy manual process. A previous research project, MINT, produced a few thousand videos of child-parent interactions in a controlled environment in order to study children’s language development. These videos were filmed across multiple sessions, tracking the same children from the age of 3 months to 7 years. LÄS MER

  4. 3. Improving 3D Remote Guidance using Shared AR Spaces : Separating responsibility of tracking and rendering 3D AR‐objects

    Master-uppsats, Linköpings universitet/Institutionen för datavetenskap

    Författare :Erik Mansén; [2022]
    Nyckelord :augmented reality; AR; mixed reality; MR; remote guidance; remote collaboration; video-mediated communication; telepresence;

    Sammanfattning : Two common problems in Remote Guidance applications include the remote guides lack of direct control over their view into the worker’s physical environment and the difficulties that arise with trying to place virtual 3D objects in a real 3D environment,via a moving, shaky, 2D image.The first issue can be called a lack of remote spatial awareness, the guide can see only what the worker enables them to see.

  5. 4. Investigating the Effects of Robots Reacting to Human Backchanneling on Human-Robot Interaction

    Master-uppsats, Umeå universitet/Institutionen för datavetenskap

    Författare :Pauline Littbrand; [2022]
    Nyckelord :;

    Sammanfattning : In an interaction between two participants the listener continuously gives feedback to the speaker in the form of gestures and verbal utterances; this is called backchanneling. An example of commonly used backchanneling is nodding or the verbal utterance “yeah”. LÄS MER

  7. 5. Computer Vision in Fitness: Exercise Recognition and Repetition Counting

    Master-uppsats, KTH/Matematik (Avd.)

    Författare :Anna Barysheva; [2022]
    Nyckelord :Exercise classification; human action recognition; repetition counting; skeletal motion recognition; unsupervised machine learning; Övningsklassificering; igenkänning av mänsklig handling; upprepningsräkning; igenkänning av skelettrörelse; oövervakad maskininlärning;

    Sammanfattning : Motion classification and action localization have rapidly become essential tasks in computer vision and video analytics. In particular, Human Action Recognition (HAR), which has important applications in clinical assessments, activity monitoring, and sports performance evaluation, has drawn a lot of attention in research communities.
