2. 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 : 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

4. 2. Input Estimation for Teleoperation : Using Minimum Jerk Human Motion Models to Improve Telerobotic Performance

   Author : Christian Smith; Patric Jensfelt; Herman Bruyninckx; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Robot; Teleoperation; Human Motion Models; Computer science; Datavetenskap;

   Abstract : This thesis treats the subject of applying human motion models to create estimators for the input signals of human operators controlling a telerobotic system.In telerobotic systems, the control signal input by the operator is often treated as a known quantity. However, there are instances where this is not the case. READ MORE

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

   Author : Zhengrong Yao; Haibo Li; Ralf Schäfer; Umeå universitet; []
   Keywords : 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

6. 4. Parameter Estimation for Mobile Positioning Applications

   Author : Parinaz Kasebzadeh; Fredrik Gustafsson; Gustaf Hendeby; Carsten Fritsche; Fredrik Gunnarsson; Jussi Collin; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : The availability and reliability of mobile positioning algorithms depend on both the quality of measurements and the environmental characteristics. The positioning systems based on global navigation satellite systems (GNSS), for example, have typically a few meters accuracy but are unavailable in signal denied conditions and unreliable in multipath environments.

7. 5. Homography-Based Positioning and Planar Motion Recovery

   Author : Mårten Wadenbäck; Mathematical Imaging Group; []
   Keywords : ;

   Abstract : Planar motion is an important and frequently occurring situation in mobile robotics applications. This thesis concerns estimation of ego-motion and pose of a single downwards oriented camera under the assumptions of planar motion and known internal camera parameters. READ MORE
