  1. 21. Implementation and evaluation of motion correction for quantitative MRI

    University essay from Medicinsk informatik

    Author : Jonatan Larsson; [2010]
    Keywords : image analysis; image registration; local phase; SPM; qMRI; rigid transformation;

    Abstract : Image registration is the process of aligning two images such that their mutual features overlap. This is of great importance in several medical applications. In 2008 a novel method for simultaneous T1, T2 and proton density quantification was suggested. The method is in the field of quantitative Magnetic Resonance Imaging or qMRI. READ MORE

  3. 22. Simultaneous Localisation and Mapping of Indoor Environments Using a Stereo Camera and a Laser Camera

    University essay from Institutionen för systemteknik; Institutionen för datavetenskap

    Author : Anders Karlsson; Jon Bjärkefur; [2010]
    Keywords : EKF; SLAM; SAM; SJSAM; Maps; Submaps; NDT; ICP; Laser scan registration;

    Abstract : This thesis describes and investigates different approaches to indoor mapping and navigation. A system capable of mapping large indoor areas with a stereo camera and/or a laser camera mounted to e.g. a robot or a human is developed. READ MORE

  4. 23. Evaluation of Geometric Accuracy and Image Quality of an On-Board Imager (OBI)

    University essay from Medicinsk strålningsfysik (tills m KI)

    Author : Milos Djordjevic; [2007]
    Keywords : Image-guided radiotherapy; Cone-beam CT; OBI; Quality Assurance;

    Abstract : In this project several tests were performed to evaluate the performance of an On-Board Imager® (OBI) mounted on a clinical linear accelerator. The measurements were divided into three parts; geometric accuracy, image registration and couch shift accuracy, and image quality. READ MORE

  5. 24. Scene-based correction of image sensor deficiencies

    University essay from Bildbehandling; Tekniska högskolan

    Author : Petter Torle; [2003]
    Keywords : Technology; nonuniformity correction; fixed pattern noise; scene-based; motion estimation; sequence; registration; IR; FPN; NUC; TEKNIKVETENSKAP;

    Abstract : This thesis describes and evaluates a number of algorithms for reducing fixed pattern noise in image sequences. Fixed pattern noise is the dominantnoise component for many infrared detector systems, perceived as a superimposed pattern that is approximately constant for all image frames. READ MORE
