  1. 1. Classification of Drill Core Textures for Process Simulation in Geometallurgy : Aitik Mine, Sweden

    Master-uppsats, Luleå tekniska universitet/Mineralteknik och metallurgi

    Författare :Glacialle Tiu; [2017]
    Nyckelord :ore texture; texture classification; Machine Learning; drill core photography; scanning electron microscope; X-ray microtomography; mineral mapping; stereology;

    Sammanfattning : This thesis study employs textural classification techniques applied to four different data groups: (1) visible light photography, (2) high-resolution drill core line scan imaging (3) scanning electron microscopy backscattered electron (SEM-BSE) images, and (4) 3D data from X-ray microtomography (μXCT). Eleven textural classes from Aitik ores were identified and characterized. LÄS MER

  3. 2. Investigation of the prognostic value of CT and PET-based radiomic image features in oropharyngeal squamous cell carcinoma

    Master-uppsats, Lunds universitet/Medicinsk strålningsfysik, Lund; Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Mohammed Mosad Said; [2016]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : Background Medical data in the form of radiographic routine scans is steadily accumulating. The analysis of such data through automated quantitative methods is believed to produce new information which would allow for more personalization of therapy. The present thesis investigated the use of such methods in head and neck cancer. LÄS MER

  4. 3. Photometric Methods for Autonomous Tree Species Classification and NIR Quality Inspection

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Inna Valieva; [2015]
    Nyckelord :RGB imaging; NIR imaging; Artificial Neural Networks; Tree species classification; Gray Level Co-occurrence Matrix; Maximally Stable Extremal Regions;

    Sammanfattning : In this paper the brief overview of methods available for individual tree stems quality evaluation and tree species classification has been performed. The use of Near Infrared photometry based on conifer’s canopy reflectance measurement in near infrared range of spectrum has been evaluated for the use in autonomous forest harvesting. LÄS MER

  5. 4. Texture Feature Analysis of Breast Lesions in Automated 3D Breast Ultrasound

    Master-uppsats, Institutionen för informationsteknologi

    Författare :Haixia Liu; [2013]
    Nyckelord :;

    Sammanfattning : This thesis investigated a variety of texture features performances  on classifying and detecting breast lesions in automated  3D breast ultrasound (ABUS) images with computer-aided diagnosis and detection  system. Regions detected  by the computer-aided detection  system could be categorized into benign and malignant classes, which are supposed to have different texture features. LÄS MER
