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

    Detta är en avhandling från Karlskrona : Blekinge Institute of Technology

    Författare :Jiandan Chen; ; [2008]
    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.

    Sammanfattning : In our society with its aging population, the design and implementation of a highperformance distributed multi-sensor and information system for autonomous physical services become more and more important. In line with this, this thesis proposes an Intelligent Multi-Sensor System, IMSS, that surveys a human activities space to detect and identify a target for a specific service. LÄS MER

  3. 13. Computerized Cell and Tissue Analysis

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Sammanfattning : The latest advances in digital cameras combined with powerful computer software enable us to store high-quality microscopy images of specimen. Studying hundreds of images manually is very time consuming and has the problem of human subjectivity and inconsistency. LÄS MER

  4. 14. Radiation dose and image quality in diagnostic radiology : optimization of the dose - image quality relationship with clinical experience from scoliosis radiography, coronary intervention and a flat-panel digital detector

    Detta är en avhandling från Linköping : Linköpings universitet

    Författare :Håkan Geijer; Hans Ringertz; [2001]

    Sammanfattning : Det är känt att röntgenstrålning kan orsaka cancersjukdomar, hudskador och andra sidoeffekter. Därför är det viktigt och även föreskrivet i lag att strålexpaneringen inom diagnostisk radiologi skall sänkas så långt som möjligt. Detta kallas på engelska ALARA-principen (As Low As Reasonably Achievable). LÄS MER

  5. 15. Towards Automatic Image Analysis for Computerised Mammography

    Detta är en avhandling från Umeå : Datavetenskap
