  1. 1. Inferring 3D trajectory from monocular data using deep learning

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

    Författare :Victor Sellstedt; [2021]
    Nyckelord :Deep Learning; Monocular trajectory estimation; Time series prediction; Synthetic data; Djupinlärning; Inferens från monkulära sekvenser; Tidsserieanalys; Syntetisk data;

    Sammanfattning : Trajectory estimation, with regards to reconstructing a 3D trajectory from a 2D trajectory, is commonly achieved using stereo or multi camera setups. Although projections from 3D to 2D suffer significant information loss, some methods approach this problem from a monocular perspective to address limitations of multi camera systems, such as requiring points in to be observed by more than one camera.

  3. 2. Implementation and verification of a quantitative MRI method for creating and evaluating synthetic MR images

    Master-uppsats, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Författare :Aleksander Blagoiev; [2020]
    Nyckelord :MRI; Quantitative MRI; Synthetic MRI;

    Sammanfattning : The purpose of this thesis was to implement and quantitatively test a quantitative MRI (qMRI) method, from which synthetic MR images are created and also evaluated. The parameter maps of T1, T2*, and effective proton density (PD*) were tested with reference tubes containing different relaxation times, and concentrations of water (H2O) and heavy water (D2O).

  4. 3. APPRAISAL OF DIAMONDS AND GEMSTONES : How to facilitate the separation of natural and synthetic gemstones

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för ekonomi, teknik och samhälle

    Författare :Anna Sahlin; [2018]
    Nyckelord :Desig; designprocess; teknisk design; civilingenjör; produkt design; produkt framtagning;

    Sammanfattning : One major problem in the gemstone industry is that it is difficult to determine whether if a gemstone is natural or synthetic. Natural gemstones are found in the interior of the earth while the synthetic gems are created by people. LÄS MER

  5. 4. Direction estimation using visual odometry

    Uppsats för yrkesexamina på avancerad nivå, KTH/Skolan för datavetenskap och kommunikation (CSC)

    Författare :Clément Masson; [2015]
    Nyckelord :direction; estimation; visual odometry; camera; compass; keypoint; feature; bundle adjustment;

    Sammanfattning : This Master thesis tackles the problem of measuring objects’ directions from a motionlessobservation point. A new method based on a single rotating camera requiring the knowledge ofonly two (or more) landmarks’ direction is proposed. LÄS MER
