  1. 1. Coverage Motion Planning for Search and Rescue Missions : A Costmap Based Approach for fixed wing UAVs using Simulated Annealing &Cubic Splines

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Author : Fredrik Rönnkvist; [2023]
    Keywords : Motion planning; Path planning; Cubic splines; Coverage path planning.;

    Abstract : The present study proposes a novel approach to Coverage Path Planning for unmanned aerial vehicle (UAV) inspired by the Orienteering Problem. The main goal is to develop an algorithm suitable for Search and Rescue Missions, which can produce a search pattern with dynamical constrains, that is not limited to the traditional back-and-forth motion or spiral patterns.

  3. 2. Image Reconstruction Techniques using Kaiser Window in 2D CT Imaging

    University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Author : Md Monowarul Islam; Muftadi Ullah Arpon; [2020]
    Keywords : CT Imaging; Parallel-Beam Projection; 2D FFT; Radon Transform; Filters; Window Functions; Kaiser window; Inverse Fourier Transform; FBP.;

    Abstract : The traditional Computed Tomography (CT) is based on the Radon Transform and its inversion. The Radon transform uses parallel beam geometry and its inversion is based on the Fourier slice theorem. READ MORE

  4. 3. Data association for object-based SLAM

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Kamil Kaminski; [2020]
    Keywords : ;

    Abstract : The thesis tackles the problem of data association for monocular object-basedSLAM, which gets often omitted in related works. A method for estimating ellipsoid object landmark representations is implemented. READ MORE

  5. 4. Optimization of Non-Local Means filtration for Cone Beam Computed Tomography

    University essay from

    Author : Lina Berneryd; [2019-07-03T13:42:50Z 2019-07-03T13:42:50Z 2015]
    Keywords : Matematik; Grundläggande vetenskaper; Mathematics; Basic Sciences;

    Abstract : Cone Beam Computed Tomography (CBCT) is a medical imaging technique used to visualize the internals of an object from a set of X-ray images. The X-ray images are taken with a cone shaped X-ray beam at many angles around the object being visualized. The images are then back projected through a volume forming a 3D representation of the object. READ MORE

  6. 5. Optimization of Acquisition Time for 177- Lu SPECT with Two Energy Windows

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Fanny Mörnsjö Centofanti; [2019]
    Keywords : Medicine and Health Sciences;

    Abstract : Background & Aim: The imaging process following the treatment of 177Lu-DOTATATE is in some medical clinics demanding on both patients and the clinic. Usually a number of images are acquired, with different time intervals to the time of injection. READ MORE
