  1. 1. Construction and evaluation of a lossless image format, Carbonara

    Kandidat-uppsats, Linköpings universitet/Institutionen för datavetenskap

    Författare :Viktor Rösler; [2023]
    Nyckelord :Data Compression; Image Compression; Image Format; Software Development;

    Sammanfattning : High-speed laser triangulation 3D cameras, such as the Ranger3 from SICK, transmit image data to a PC for processing. The camera’s operational speed is constrained by the capabilities of the transmission link. By compressing the data, the bandwidth requirements of the camera is reduced. LÄS MER

  3. 2. Robust visual SLAM with compressed image data : A study of ORB-SLAM3 performance under extreme image compression

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

    Författare :Guangzhi Wang; [2023]
    Nyckelord :ORB-SLAM3; compression; image feature; localization accuracy; internal parameter; hybrid compressing; brightness enhancement; ORB-SLAM3; kompression; bildfunktion; lokaliseringsnoggrannhet; intern parameter; hybridkomprimering; ljusstyrkeförstärkning;

    Sammanfattning : Offloading SLAM to the edge/cloud is now becoming an attractive option to greatly decrease device energy usage. The new SLAM solution involves compressing image data on the device before transmission, allowing a further decrease in the network bandwidth when performing SLAM at the edge/cloud. LÄS MER

  4. 3. Size effect in wood : Characterization of mechanical properties using digital image correlation method

    Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Tillämpad mekanik

    Författare :Amir Saeidi; Olafur Johannsson; [2023]
    Nyckelord :compression test longitudinal direction; digital image corre- lation DIC ; ncorr; phyton; pinewood; size effect; stiffness matrix; wood- construction; YAWCAM; young’s modulus; digital image correlation DIC ; elasticitetsmodul; furu; kom- pressionstest längs fiberriktning; ncorr; phyton; storlekseffekt; styvhetsma- tris; trä-konstruktion; YAWCAM;

    Sammanfattning : As a natural composite material, wood exhibits complex structural char-acteristics and diverse behavior under compression and tensile forces. Itsanisotropic nature results in mechanical properties that vary depending onthe load direction along its longitudinal, tangential, and radial grains. LÄS MER

  5. 4. Experimental Testing of EPS-foam

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Carl Göransson; Erik Arnald; [2023]
    Nyckelord :Solid Mechanics; EPS; Experimental testing; Hållfasthetslära; EPS; Experimentell testning;

    Sammanfattning : The aim of this master thesis was to investigate the mechanical properties of ExpandedPolystyrene (EPS) through experimental testing. The strain was measured on thespecimen’s surface with Digital Image Correlation (DIC), in order to investigate howthe first principal strain at fracture initiation depends on the loading of the material.

  7. 5. Synchronized assessment ofcompression of corrugatedboard : Mechanics and visualization

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad mekanik

    Författare :Johan Bürger; [2023]
    Nyckelord :corrugated board; compression; image analysis; thresholding; modelling; Maxwell; spring dashpot;

    Sammanfattning : Flexographic printing involves driving a paper substrate through the gap between two cylinders, where one of the cylinders has a print form layer covered in ink. The ink transfer from the print form to the paper is dependent on the pressure between the paper substrate and the cylinders. LÄS MER
