  1. 11. Developing a New Method for MRI Triggering Using Doppler Ultrasound

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Usama Gazay; [2019]
    Nyckelord :;

    Sammanfattning : Purpose: Magnetic Resonance Imaging (MRI) is a medical imaging technique used in radiology to produce high quality images of the anatomy and the physiological processes of the body. Cardiac gating is a triggering system used for the MRI scanner to synchronize the MRI scanner with the cardiac cycle of the patient while imaging. LÄS MER

  3. 12. Robustness of a neural network used for image classification : The effect of applying distortions on adversarial examples

    Uppsats för yrkesexamina på grundnivå, Högskolan i Gävle/Datavetenskap

    Författare :Rasmus Östberg; [2018]
    Nyckelord :LeNet; Distorted Images; MNIST; Adversarial Examples;

    Sammanfattning : Powerful classifiers as neural networks have long been used to recognise images; these images might depict objects like animals, people or plain text. Distorted images affect the neural network's ability to recognise them, they might be distorted or changed due to distortions related to the camera. LÄS MER

  4. 13. Estimation and Correction of the Distortion in Forensic Image due to Rotation of the Photo Camera

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

    Författare :Sathwika Bavikadi; Venkata Bharath Botta; [2018]
    Nyckelord :Hough Transformation; Hough Circular Transformation; Image Rotation; Forensic Scales.;

    Sammanfattning : Images, in contrast to text, represent an effective and natural communication media for humans, due to their immediacy and the easy way to understand the image content. Shape recognition and pattern recognition are one of the most important tasks in the image processing. LÄS MER

  5. 14. Representing Bergslagen for tourism – a post-feminist approach : Androcentric representations of the industrial heritage in central Sweden

    Master-uppsats, Högskolan Dalarna/Turismvetenskap

    Författare :Minéa Funk; [2018]
    Nyckelord :Androcentricism; Bergslagen; Industrial heritage tourism; Post-feminist theory; Representations.;

    Sammanfattning : Marketing material used in promotion of industrial heritage sites for tourism creates representations of said cultural heritage. In order to increase the touristic value of the historical industrial sites marketers can create or make a place attractive through careful selection of images and texts. LÄS MER

  7. 15. Short Range Millimeter-Wave Inverse Synthetic Aperture Radar Imaging

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik
