  1. 21. Computational Models for Animating 3D Virtual Faces

    Författare :Marco Fratarcangeli; Robert Forchheimer; Marco Schaerf; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Automatic synthesis of facial animation in Computer Graphics is a challenging task and although the problem is three decades old by now, there is still not a unified method to solve it. This is mainly due to the complex mathematical model required to reproduce the visual meanings of facial expressions coupled with the computational speed needed to run interactive applications.

  3. 22. Postmortem debugging of distributed systems

    Författare :Lars Strömberg; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis describes the design and implementation of a debugger for parallel programs executing on a system of loosely coupled processors. A primary goal has been to create a debugging environment that structurally matches the design of the distributed program. LÄS MER

  4. 23. Model-based coding : extraction, coding, and evaluation of face model parameters

    Författare :Jörgen Ahlberg; Andrew Senior; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : This thesis deals with model-based coding of human faces for low bitrate communication. The basicidea of model-based coding is that the appearance and motion of a human face are analysed. By thisanalysis, compact parameters allowing realistic visualization of a synthetic face are extracted. LÄS MER

  5. 24. Travelling through time : Students’ interpretation of evolutionary time in dynamic visualizations

    Författare :Jörgen Stenlund; Lena Tibell; Konrad Schönborn; Niklas Gericke; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Evolution; visualization; time; learning; threshold; zooming;

    Sammanfattning : Evolutionary knowledge is important to understand and address contemporary challenges such as loss of biodiversity, climate change and antibiotic resistance. An important aspect that is considered to be a threshold concept in teaching and learning about evolution is the time it involves. LÄS MER

  7. 25. 3D Occlusion Management and Causality Visualization

    Författare :Niklas Elmqvist; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; causality; occlusion reduction; interaction techniques; visualization; occlusion management; information visualization; causal relations;

    Sammanfattning : This thesis is split into two parts: one part dealing with the management of occlusion in 3D environments, the other with the visualization of causal relations. Both of these parts fall within the general framework of visualization---the graphical representation of data (abstract or concrete) with the purpose of amplifying cognition---but they do so in different ways.
