  1. 1. Bringing the avatar to life : Studies and developments in facial communication for virtual agents and robots

    Författare :Samer Al Moubayed; Jonas Beskow; Stefan Kopp; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Avatar; Speech Communication; Facial animation; Nonverbal; Social; Robot; Human-like; Face-to-face; Prosody; Pitch; Prominence; Furhat; Gaze; Head-pose; Dialogue; Interaction; Multimodal; Multiparty; SRA - ICT; SRA - Informations- och kommunikationsteknik;

    Sammanfattning : The work presented in this thesis comes in pursuit of the ultimate goal of building spoken and embodied human-like interfaces that are able to interact with humans under human terms. Such interfaces need to employ the subtle, rich and multidimensional signals of communicative and social value that complement the stream of words – signals humans typically use when interacting with each other.

  3. 2. Talking Heads - Models and Applications for Multimodal Speech Synthesis

    Författare :Jonas Beskow; KTH; []
    Nyckelord :Talking heads; facial animation; speech synthesis; coarticulation; intelligibility; embodied conversational agents;

    Sammanfattning : This thesis presents work in the area of computer-animatedtalking heads. A system for multimodal speech synthesis hasbeen developed, capable of generating audiovisual speechanimations from arbitrary text, using parametrically controlled3D models of the face and head. LÄS MER

  4. 3. 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.

  5. 4. 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

  7. 5. Model Based Coding : Initialization, Parameter Extraction and Evaluation

    Författare :Zhengrong Yao; Haibo Li; Ralf Schäfer; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Model-based coding; Motion estimation; Vision based tracking; Initialization; Analysis-by-Synthesis; Texture mapping; Active tracking.; Signalbehandling; Signal processing; Signalbehandling; Signal Processing; signalbehandling;

    Sammanfattning : This thesis covers topics relevant to model-based coding. Model-based coding is a promising very low bit rate video coding technique. The idea behind this technique is to parameterize a talking head and to extract and transmit the parameters describing facial movements. At the receiver, the parameters are used to reconstruct the talking head. LÄS MER
