  1. 1. Identification of shape errors in a parabolic solar collector : An improvement to the analysing algorithms examining the solar collector from optical measurements

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Malin Gelfgren; [2023]
    Nyckelord :;

    Sammanfattning : Increasing global warming with droughts, forest fires and melting polar ice has forced the world to speed up the transition from fossil fuel to fossil free energy. A big part of it is the use of solar energy. To obtain solar thermal energy, different sorts of solar collectors have been developed. LÄS MER

  3. 2. Human pose estimation in low-resolution images

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

    Författare :Hugo Nilsson; [2022]
    Nyckelord :Human Pose Estimation; Low-Resolution Images; Heatmap Decoding; Computer Vision; Deep Learning; Mänsklig Poseuppskattning; Lågupplösta Bilder; Färgdiagram Avkodning; Datorseende; Djupinlärning;

    Sammanfattning : This project explores the understudied, yet important, case of human pose estimation in low-resolution images. This is done in the use-case of images with football players of known scale in the image. Human pose estimation can mainly be done in two different ways, the bottom-up method and the top-down method.

  4. 3. Automating Feature-Extraction for Camera Calibration Through Machine Learning and Computer Vision

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

    Författare :Elias Åkeborg; [2021]
    Nyckelord :Machine learning; Computer vision; Feature-extraction; Classification; Camera Calibration; DeepLab; U-Net; Ridge Detection; Sub-pixel optimization; Artificial Intelligence; Technology and Engineering;

    Sammanfattning : Machine learning as a field has expanded in an explosive manner, with more companies interested in using the technology. One of these companies, Spiideo, uses Machine learning to automatically stream and record sports, highlighting key events - all automatically without a cameraman. LÄS MER

  5. 4. Polarisation-resolved super-resolution microscopy

    Master-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Författare :Wouter Duverger; [2021]
    Nyckelord :biophysics; microscopy; super-resolution microscopy; polarisation microscopy; STED; Physics and Astronomy;

    Sammanfattning : This project aims to implement polarisation microscopy on the Tegenfeldt STED (stimulated emission depletion) microscope. STED microscopy is a targeted optical super-resolution method that can attain sub-diffraction resolution using visible light. LÄS MER

  7. 5. Laser line extraction with sub-pixel accuracy for 3D measurements

    Master-uppsats, Linköpings universitet/Beräkningsmatematik; Linköpings universitet/Tekniska fakulteten

    Författare :Mirjam Mattsson; [2020]
    Nyckelord :laser line extraction; Steger’s method; Gaussian fitting; Centre of Mass;

    Sammanfattning : One 3D measurement method is laser scanning. By projecting and photographing a laser line, the centre line coordinates of the laser can be obtained with centre line detection methods and then be used to generate 3D model of the scanned object. LÄS MER
