  1. 11. Evolution of Vertebrate Vision by Means of Whole Genome Duplications : Zebrafish as a Model for Gene Specialisation

    Författare :David Lagman; Dan Larhammar; Xesús M Abalo; Finn Hallböök; Stephan Neuhauss; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; phylogenetics; evolution; vision; visual opsin; transducin; PDE6; genome duplications; subfunctionalisation; Medicinsk vetenskap; Medical Science;

    Sammanfattning : The signalling cascade of rods and cones use different but related protein components. Rods and cones, emerged in the common ancestor of vertebrates around 500 million years ago around when two whole genome duplications took place, named 1R and 2R. LÄS MER

  3. 12. Embodied Visual Object Recognition

    Författare :Marcus Wallenberg; Per-Erik Forssén; Michael Felsberg; Aleš Ude; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; object recognition; machine learning; computer vision;

    Sammanfattning : Object recognition is a skill we as humans often take for granted. Due to our formidable object learning, recognition and generalisation skills, it is sometimes hard to see the multitude of obstacles that need to be overcome in order to replicate this skill in an artificial system.

  4. 13. Object Detection and Recognition in Unstructured Outdoor Environments

    Författare :Ahmad Ostovar; Thomas Hellström; Ola Ringdahl; Mårten Björkman; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer vision; Deep Learning; Harvesting Robots; Automatic Detection and Recognition; Computer Science; datalogi;

    Sammanfattning : Computer vision and machine learning based systems are often developed to replace humans in harsh, dangerous, or tedious situations, as well as to reduce the required time to accomplish a task. Another goal is to increase performance by introducing automation to tasks such as inspections in manufacturing applications, sorting timber during harvesting, surveillance, fruit grading, yield prediction, and harvesting operations.

  5. 14. Hyperspectral Image Generation, Processing and Analysis

    Författare :Hamed Hamid Muhammed; Ewert Bengtsson; Tommy Lindell; Erkki Oja; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bildanalys; hyperspectral imaging; colour filter mosaics; remote sensing; crop reflectance; surface water quality; disease severity; plant density; linear system of equations; waste water detection; chlorophyll a; suspended paticulate matter; weighted fixed neural networks; weighted incremental neural networks; camera spectrometer; Bildanalys; Image analysis; Bildanalys;

    Sammanfattning : Hyperspectral reflectance data are utilised in many applications, where measured data are processed and converted into physical, chemical and/or biological properties of the target objects and/or processes being studied. It has been proven that crop reflectance data can be used to detect, characterise and quantify disease severity and plant density. LÄS MER

  7. 15. Modelling and controlling an offset lithographic printing process

    Författare :Cristofer Englund; Högskolan i Halmstad; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Neural networks; Self-organizing map; Data mining; Outlier detection; Committee; Multiple models; Colour print control; Image analysis; Bildanalys;

    Sammanfattning : The objective of this thesis is to provide methods for print quality enhancements in an offset lithographic printing proess. Various parameters characterising the print quality are recognised, however, in this work print quality is defined as the deviation of the amount of ink in a sample image from the reference print.
