    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

  3. 2. Three dimensional data analysis for the separation and sizing of laboratory rock piles

    Författare :Matthew Thurley; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Signal Processing;

    Sammanfattning : The size distribution of piles of blasted and crushed rock in mining is so closely related to the economics of the mine that it must be measured quickly and accurately. This thesis develops a mathematical and 3D imaging solution for determining the size distribution of laboratory rock piles based on surface measurements of the pile... LÄS MER
