  1. 21. A Multi Sensor System for a Human Activities Space : Aspects of Planning and Quality Measurement

    Författare :Jiandan Chen; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 3D Reconstruction; Iso-disparity Surfaces; Depth Reconstruction Uncertainty; Uncertainty Analysis; Dither; Sensor Placement; Multi Stereo View; Image Quality; Human Factor;

    Sammanfattning : In our aging society, the design and implementation of a high-performance autonomous distributed vision information system for autonomous physical services become ever more important. In line with this development, the proposed Intelligent Vision Agent System, IVAS, is able to automatically detect and identify a target for a specific task by surveying a human activities space.

  3. 22. On Signal Dependent Basis Functions, Estimation of Event Related Potentials and Multiple Window Spectrum Analysis

    Författare :Maria Hansson; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Signal processing; spectrum analysis; multiple windows; anaesthesia; Nb-trough; damped sinusoids; single ERP; Signal dependent basis functions; Event Related Potentials;

    Sammanfattning : The three parts of this thesis are different examples of utilization of signal dependent basis functions in the estimation procedure. The first part surveys a number of parametric methods applied to estimation of single ERP (P300). LÄS MER

  4. 23. Towards Robust Visual Localization in Challenging Conditions

    Författare :Carl Toft; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; autonomous vehicles; self-driving cars; camera pose estimation; long-term localization; Visual localization; benchmark;

    Sammanfattning : Visual localization is a fundamental problem in computer vision, with a multitude of applications in robotics, augmented reality and structure-from-motion. The basic problem is to, based on one or more images, figure out the position and orientation of the camera which captured these images relative to some model of the environment. LÄS MER

  5. 24. Low Power and Low Complexity Shift-and-Add Based Computations

    Författare :Kenny Johansson; Oscar Gustafsson; Lars Wanhammar; Izzet Kale; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; FIR filters; Function approximation; Digital circuits; Computer arithmetic; Constant multiplication; Addition; Low power; Switching activity estimation; Electronics; Elektronik;

    Sammanfattning : The main issue in this thesis is to minimize the energy consumption per operation for the arithmetic parts of DSP circuits, such as digital filters. More specific, the focus is on single- and multiple-constant multiplications, which are realized using shift-and-add based computations. The possibilities to reduce the complexity, i.e. LÄS MER

  7. 25. Modelling driver behaviour in run-off-road crashes: Applications in safety system development and safety benefit estimation

    Författare :Daniel Nilsson; Chalmers tekniska högskola; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; advanced driver assistance systems; effectiveness assessment; run-off-road crashes; predictive processing; driver behaviour; cluster analysis;

    Sammanfattning : Run-off-road crashes have been identified as a major concern for automobile safety and several advanced driver assistance systems (ADASs) targeting run-off-road crashes are on the market today. Assessment of ADASs require relevant test scenarios and valid computational models of driver behaviour. LÄS MER
