  1. 21. 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

  3. 22. Normalized Convolution Network and Dataset Generation for Refining Stereo Disparity Maps

    University essay from Linköpings universitet/Datorseende

    Author : Daniel Cranston; Filip Skarfelt; [2019]
    Keywords : Disparity Map; Disparity Refinement; Dataset Generation; Neural Network; Normalized Convolution;

    Abstract : Finding disparity maps between stereo images is a well studied topic within computer vision. While both classical and machine learning approaches exist in the literature, they frequently struggle to correctly solve the disparity in regions with low texture, sharp edges or occlusions.

  4. 23. Map Matching to road segments using Hidden Markov Model with GNSS, Odometer and Gyroscope

    University essay from Linköpings universitet/Programvara och system

    Author : Hugo Lindholm; [2019]
    Keywords : map matching; hmm; hidden markov model; gnss;

    Abstract : In this thesis the Hidden Markov Model (HMM) is used in the process of map matching to investigate the accuracy for road segment map matching. A few HMM algorithms using a Global Navigation Satellite System (GNSS) receiver, odometer and gyroscope sensors are presented. The HMM algorithms are evaluated on four accuracy metrics. READ MORE

  5. 24. Improving movie recommendations through social media matching

    University essay from Malmö universitet/Fakulteten för teknik och samhälle (TS)

    Author : Roman Kuroptev; Anton Lagerlöf; [2019]
