  1. 1. Ocean Exploration with Artificial Intelligence

    University essay from Göteborgs universitet/Institutionen för data- och informationsteknik

    Author : Sarah Al-Khateeb; Lisa Bodlak; [2021-07-06]
    Keywords : computer science; deep learning; generative adversarial networks; data augmentation; object detection; underwater image; computer vision;

    Abstract : Large and diverse data is crucial to train object detection systems properly and achieve satisfactory prediction performance. However, in some areas, such as ma rine science, gathering sufficient data is challenging and sometimes even infeasible. Working with limited data can result in overfitting and poor performance.

  2. 2. Monocular Visual Odometry for Autonomous Underwater Navigation : An analysis of learning-based monocular visual odometry approaches in underwater scenarios

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

    Author : Andrea Caraffa; [2021]
    Keywords : Deep Learning; Monocular Visual Odometry; Computer Vision; Autonomous Underwater Navigation; Autonomous Underwater Vehicle; Djupinlärning; Monokulär Visuell Odometri; Datorseende; Autonom Undervattensnavigering; Autonomt Undervattensfordon;

    Abstract : Visual Odometry (VO) is the process of estimating the relative motion of a vehicle by using solely image data gathered from the camera. In underwater environments, VO becomes extremely challenging but valuable since ordinary sensors for on-road localization are usually unpractical in these hostile environments. READ MORE

  3. 3. Canonical Representation of sidescan sonar images for robotics application

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

    Author : Hongsheng Chang; [2021]
    Keywords : ;

    Abstract : Sidescan sonar (SSS) is crucial in underwater investigation as it is cheaper and provide wider detection range. Sidescan sonars are typically mounted on Autonomous Underwater Vehicles (AUVs) or vessels. READ MORE

  4. 4. Multi-method based characterization of calving events at Sálajiegna Glacier - Lake Sulitelma, Northern Sweden

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Martin Schulthess; [2021]
    Keywords : Glaciology; Glacier; Glaciers; Calving; calving front; detection algorithm; Acoustic; Acoustics; Photogrammetry; ice-ocean interactions; UAV; drone; time-lapse; Salajiegna;

    Abstract : Sea level rise concerns millions of people in coastal areas across the globe. One of the largest uncertainties to project future sea level rise is the frontal ablation (accounting for calving and submarine melt) at marine ice margins, around the Greenland and Antarctic Ice Sheet.

  5. 5. Local Feature Correspondence on Side-Scan Sonar Seafloor Images

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

    Author : Li Ling; [2021]
    Keywords : ;

    Abstract : In underwater environments, the perception and navigation systems are heavily dependent on the acoustic wave based sonar technology. Side-scan sonar (SSS) provides high-resolution, photo-realistic images of the seafloor at a relatively cheap price. READ MORE
