1. 1. Robust light source detection for AUV docking

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Joar Edlund; [2023]
   Nyckelord :Autonomous Underwater Vehicle; Docking; Detection; Poseestimation; Visual Navigation; Autonoma Undervattensfordon; Dockning; Detektering; Positionsestimering; Visuell Navigation;

   Sammanfattning : For Autonomous Underwater Vehicles (AUVs) to be able to conduct longterm surveys, the ability to return to a docking station for maintenance and recharging is crucial. A dynamic docking system where a slowly moving submarine acts as the docking station provides increased hydrodynamic control and reduces the impact of environmental disturbances. LÄS MER

3. 2. Segmentation of Neuronal Cells Using Simplistic Methods : A Comparison of the Mean Shift Algorithm and Otsu’s Method

   Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Alex Gunnarsson; Filip Karlsson; [2023]
   Nyckelord :;

   Sammanfattning : Information regarding specific neuronal characteristics, such as shape and distribution, is essential for quantifying the brain structure and modelling accurate computer simulations. To this end, it is important to perform cell segmentation; to isolate the cells in a given image from the surrounding tissue, so it can be further analysed. LÄS MER

4. 3. Facial recognition techniques comparison for in-field applications : Database setup and environmental influence of the access control

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för visuell information och interaktion

   Författare :Gustav Norvik; [2022]
   Nyckelord :facial recognition; deep learning; machine learning; computer vision; image processing; artificial intelligence;

   Sammanfattning : A currently ongoing project at Stanley Security is to develop a facial recognition system as access control system to prevent theft of heavy vehicles for terrorist purposes. As of today, there are several providers of facial recognition techniques and the spectrum ranges from multi dollar licenses to easy access open source. LÄS MER

5. 4. Image Augmentation in Generation of Real-Life Disturbances : An Evaluation of Image Augmentation Techniques for Log-end Identification

   Kandidat-uppsats, Linnéuniversitetet/Institutionen för datavetenskap och medieteknik (DM)

   Författare :Timothy Lottering; Irfan Omer; [2022]
   Nyckelord :Augmentation; Model Training; Image Transformations;

   Sammanfattning : Image augmentation is a field that covers the subject area of altering existing data to create more for the use of model training processes. It may be seen as the practice of expanding upon existing data using a range of techniques that employ transformations to improve the diversity of training sets when applied to machine learning.

7. 5. Potentially harmful, probably harmlessDefining and reducing false positives in digital risk assessment

   L3-uppsats, Uppsala universitet/Institutionen för psykologi

   Författare :Kajsa Mohammar; Josefin Windahl; [2022]
   Nyckelord :digital risk assessment; false positives; lone offenders; text analysis; dictionaries;

   Sammanfattning : An area of research that has attracted more and more attention lately is digital risk assessment. This is due to its promising potential of identifying lone offenders, who often utilise digital platforms to express their thoughts and opinions. LÄS MER
