  1. 1. Pixel correspondences for SLAM using sidescan sonar with canonical representations

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

    Författare :Weiqi Xu; [2022]
    Nyckelord :;

    Sammanfattning : Acoustic instruments play an important role in autonomous underwater vehicles (AUVs). Sidescan sonar (SSS) detects a wider range, provides photo-realistic images in high resolution, and has lower price than the multibeam echo sounder (MBES). LÄS MER

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

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

    Författare :Li Ling; [2021]
    Nyckelord :;

    Sammanfattning : 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. LÄS MER

  3. 3. Adaptive Losses for Camera Pose Supervision

    Master-uppsats, Linköpings universitet/Datorseende

    Författare :Marcus Dahlqvist; [2021]
    Nyckelord :camera pose supervision; camera pose; local features; feature descriptors; dense feature descriptors; correspondence image matching; feature matching;

    Sammanfattning : This master thesis studies the learning of dense feature descriptors where camera poses are the only supervisory signal. The use of camera poses as a supervisory signal has only been published once before, and this thesis expands on this previous work by utilizing a couple of different techniques meant increase the robustness of the method, which is particularly important when not having access to ground-truth correspondences.

  4. 4. Correspondence-based pairwise depth estimation with parallel acceleration

    Kandidat-uppsats, Mittuniversitetet/Avdelningen för informationssystem och -teknologi

    Författare :Nadine Bartosch; [2018]
    Nyckelord :Depth estimation; disparity; stereo vision; stereo correspondence; NVIDIA; GPU; CUDA; parallelization;

    Sammanfattning : This report covers the implementation and evaluation of a stereo vision corre- spondence-based depth estimation algorithm on a GPU. The results and feed- back are used for a Multi-view camera system in combination with Jetson TK1 devices for parallelized image processing and the aim of this system is to esti- mate the depth of the scenery in front of it.

  5. 5. Evaluation of the Catalyst system for patient positioning during breast cancer treatment

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Malin Kügele; [2012]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : Bröstcancer är den vanligaste formen av cancer hos kvinnor. Fler än 7000 diagnostiseras med denna sjukdom varje år i Sverige. En del av behandlingen mot cancern är strålbehandling. LÄS MER
