  1. 1. Semantic Segmentation of Building Materials in Real World Images Using 3D Information

    Master-uppsats, Linköpings universitet/Datorseende

    Författare :Jonas Rydgård; Marcus Bejgrowicz; [2021]
    Nyckelord :Machine learning; deep learning; semantic segmentation; convolutional neural networks; building materials; material recognition;

    Sammanfattning : The increasing popularity of drones has made it convenient to capture a large number of images of a property, which can then be used to build a 3D model. The conditions of buildings can be analyzed to plan renovations. This creates an interest for automatically identifying building materials, a task well suited for machine learning. LÄS MER

  3. 2. Dynamics of Selachian (Shark) Dental Morphology During the Early Mesozoic

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Alexander Paxinos; [2017]
    Nyckelord :Early Mesozoic; Selachii; morphological disparity; geometric morphometrics; early radiation; Tidig Mesozoisk; Selachimorpha; morfologisk disparitet; geometrisk morfometri; tidig strålning;

    Sammanfattning : The ancestors of all modern day sharks and rays (Neoselachii) may have appeared during the Late Palaeozoic, but their major diversification happened sometime during the Early Mesozoic. Taxonomic evidence places the first neoselachian diversification in the Early Jurassic. LÄS MER

  4. 3. Disparity of Early Cretaceous Lamniformes sharks

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Fredrik Söderblom; [2015]
    Nyckelord :Lamniformes; disparity; Early Cretaceous; morphology; morphometric; Lamniformes; disparitet; tidig krita; morfologi; morfometri;

    Sammanfattning : The geological range of lamniform sharks stretches from present day species such as Carcharodon carcharias (great white shark) back to the at the moment oldest undoubted fossil finds during the Early Cretaceous. In this paper a geometric morphometric analysis was performed on images of Early Cretaceous lamniform teeth collected from published literature in order to examine the change in disparity (range of morphological variation within a group) throughout the time period.

  5. 4. Stereoseende i realtid

    Uppsats för yrkesexamina på grundnivå, Bildbehandling; Tekniska högskolan

    Författare :Lars Arvidsson; [2007]
    Nyckelord :stereo; disparitet; realtid; SIMD; fas; blockmatchning;

    Sammanfattning : In this thesis, two real-time stereo methods have been implemented and evaluated. The first one is based on blockmatching and the second one is based on local phase. The goal was to be able to run the algorithms at real-time and examine which one is best. LÄS MER

  7. 5. Närmaskbestämning från stereoseende

    Uppsats för yrkesexamina på grundnivå, Bildbehandling; Tekniska högskolan

    Författare :Gunnar Hedlund; [2005]
    Nyckelord :mask; närmask; stereoseende; datorseende; bildbehandling; lemur; disparitet; cvl; bofors; kamera;

    Sammanfattning : Detta examensarbete utreder avståndsbedömning med hjälp av bildbehandling och stereoseende för känd kamerauppställning. Idag existerar ett stort antal beräkningsmetoder för att få ut avstånd till objekt, men metodernas prestanda har knappt mätts. LÄS MER
