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

    Author : Farid Abedan Kondori; Li Liu; Juyang Weng; Umeå universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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;

    Abstract : 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. READ MORE

  2. 2. Model Based Coding : Initialization, Parameter Extraction and Evaluation

    Author : Zhengrong Yao; Haibo Li; Ralf Schäfer; Umeå universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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;

    Abstract : 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. READ MORE

  3. 3. Social causality in motion : Visual bias and categorization of social interactions during the observation of chasing in infancy

    Author : Martyna A. Galazka; Pär Nyström; Gustaf Gredebäck; Moritz Daum; Uppsala universitet; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; social causality; motion; animacy perception; chasing goal-directed motion; heat-seeking; EEG; P400; Nc; spatial proximity; non-contact causality; functional specialization; specialized perception; evolution; Psychology; Psykologi;

    Abstract : Since the seminal work of Fritz Heider and Marienne Simmel (1944) the study of animacy perception, or the perception and attribution of life from the motion of simple geometrical shapes has intrigued researchers. The intrigue for psychologists and vision scientists then and today centered on the stark disconnect between the simplicity of the visual input and the universal richness of the resulting percept.

  4. 4. Object Instance Detection and Dynamics Modeling in a Long-Term Mobile Robot Context

    Author : Nils Bore; John Folkesson; Joydeep Biswas; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; robotics; long-term; mapping; tracking; unsupervised learning; estimation; object modeling; Computer Science; Datalogi;

    Abstract : In the last years, simple service robots such as autonomous vacuum cleaners and lawn mowers have become commercially available and increasingly common. The next generation of service robots should perform more advanced tasks, such as to clean up objects. READ MORE

  5. 5. Design and Implementation of a Maritime Traffic Modeling and Anomaly Detection Method

    Author : Ewa Osekowska; Blekinge Tekniska Högskola; []

    Abstract : Nowadays ships are usually equipped with a system of marine instruments, one of which is an Automatic Identification System (AIS) transponder. The availability of the global AIS ship tracking data opened the possibilities to develop maritime security far beyond the simple collision prevention. READ MORE
