  1. 1. Distance Functions and Their Use in Adaptive Mathematical Morphology

    Författare :Vladimir Ćurić; Gunilla Borgefors; Cris L. Luengo Hendriks; Hugues Talbot; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Image analysis; Distance functions; Mathematical morphology; Adaptive mathematical morphology; Image regularization; Computerized Image Processing; Datoriserad bildbehandling;

    Sammanfattning : One of the main problems in image analysis is a comparison of different shapes in images. It is often desirable to determine the extent to which one shape differs from another. This is usually a difficult task because shapes vary in size, length, contrast, texture, orientation, etc. Shapes can be described using sets of points, crisp of fuzzy. LÄS MER

  3. 2. Precise Image-Based Measurements through Irregular Sampling

    Författare :Teo Asplund; Robin Strand; Cris L. Luengo Hendriks; Matthew J. Thurley; Gunilla Borgefors; Hugues Talbot; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; image analysis; image processing; mathematical morphology; irregular sampling; adaptive morphology; missing samples; continuous morphology; path opening.; Computerized Image Processing; Datoriserad bildbehandling;

    Sammanfattning : Mathematical morphology is a theory that is applicable broadly in signal processing, but in this thesis we focus mainly on image data. Fundamental concepts of morphology include the structuring element and the four operators: dilation, erosion, closing, and opening. LÄS MER

  4. 3. Functional Morphology of Gastropods and Bivalves

    Författare :Jenny Sälgeback; Lars Holmer; John S. Peel; Jan-Ove Ebbestad; Enrico Savazzi; Anders Warén; Uppsala universitet; []
    Nyckelord :Earth sciences; Gastropoda; Bivalvia; functional morphology; constructional morphology; Geovetenskap;

    Sammanfattning : Functional morphology analyzes the relationships between form and function in organisms. However, a comprehensive analysis of any organic structure requires an integrated approach to morphology. For this purpose constructional morphology was developed, where function, phylogeny and construction together explain form. LÄS MER

  5. 4. Image Processing Architectures for Binary Morphology and Labeling

    Författare :Hugo Hedberg; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; labeling; binary image processing; morphology; Hardware architectures; real-time;

    Sammanfattning : Conventional surveillance systems are omnipresent and most are still based on analog techniques. Migrating to the digital domain grants access to the world of digital image processing enabling automation of such systems, which means extracting information from the image stream without human interaction.

  7. 5. Ontogeny and Population Biology of a Sex-Limited Colour Polymorphism

    Författare :Jessica Abbott; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; embryologi; ontogeni; animal morphology; embryology; Utvecklingsbiologi; Damselflies; Colour polymorphism; Development; Frequency-dependence; Morphology; growth animal ; ontogeny; Animal anatomy; Development biology; Djurs anatomi och morfologi; Population divergence; Animal ecology; Djurekologi;

    Sammanfattning : This study has involved investigation of number of populations of the damselfly Ischnura elegans over several years, looking at frequency changes over time, morphological differences between the sexes and the morphs, differences in growth rate and development time, differences in fecundity between the morphs, and genetic differentiation between populations.
