  4. 3. Automatic segmentation of microstructures in metals : A computer vision approach

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Oscar Larsen; [2022]
    Keywords : Image Processing; Computer Vision; Machine Learning; Deep Learning; Metallurgy; Segmentation; Bildbehandling; Datorseende; Maskininlärning; Djupinlärning; Metallurgi; Segmentering;

    Abstract : The microstructures of a metal determine the physical, electrical and chemical properties of the metal, and analysis of microstructures is therefore an important part of materials science. Modern microscopes are capable of generating a lot of high-quality micrographs in a short period of time. READ MORE

  5. 4. Machine Learning Methods for Segmentation of Complex Metal Microstructure Features

    University essay from KTH/Materialvetenskap

    Author : Daniel Fredriksson; [2022]
    Keywords : Machine learning; Metallography; Automatic segmentation; Complex microstructures; Random Forest classifier.; Maskininlärning; Metallografi; Automatisk segmentering; Komplex mikrostruktur; Random Forest klassificerare;

    Abstract : Machine learning is a growing topic with possibilities that seems endless with growing areas of applications. The field of metallography today is highly dependent on the operators’ knowledge and technical equipment to perform segmentation and analysis of the microstructure. Having expert dependents is both costly and very time-consuming. READ MORE

  6. 5. GAN-based Automatic Segmentation of Thoracic Aorta from Non-contrast-Enhanced CT Images

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)
