  1. 1. Image Segmentation and Object Identification in Cancer Tissue Slides from Fluorescence Microscopy

    University essay from Uppsala universitet/Avdelningen Vi3

    Author : Sebastian Eriksson; Fredrik Forsberg; [2023]
    Keywords : image analysis; cancer research; fluorescent microscopy; image segmentation; bildanalys; cancerforskning; fluorescensmikroskopi; bildsegmentering;

    Abstract : In cancer research, there is a need to make accurate spatial measurements in multi-layered fluorescence microscopy images. Researchers would like to measure distances in and between biological objects such as nerves and tumours, to investigate questions which includes if nerve distribution in and around tumours can have a prognostic value in cancer diagnostics.

  3. 2. Assessment of aggregate structure in porous asphalt using X-ray computed tomography

    University essay from KTH/Väg- och banteknik

    Author : Mari Haagenrud Matsson; Malex Love Valdemar Åkerblom; [2023]
    Keywords : Tomography; non-destructive testing; destructive testing; air voids content; aggregate size distribution; porous asphalt;

    Abstract : X-ray computed tomography is a technique that has been successfully utilized to characterize internal microstructure of asphalt mixtures. The city of Linköping (Sweden) developed an action plan to reduce noise; accordingly KTH and VTI developed a method to determine air void content in porous asphalt using x-ray computed tomography and an image processing software called ImageJ.

  4. 3. Cell Identification from Microscopy Images using Deep Learning on Automatically Labeled Data

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Fredrik Salomon-Sörensen; [2023]
    Keywords : Deep Learning; Cell Identification; Image Segmentation; Nuclei Segmentation; Convolutional Neural Networks; UNet; Image Analysis; Microscopy; Noisy Labels; Phase-Contrast; Automatic Labeling; Technology and Engineering;

    Abstract : In biology, cell counting provides a fundamental metric for live-cell experiments. Unfortunately, most researchers are constrained to using tedious and invasive methods for counting cells. Automatic identification of cells in microscopy images would therefore be a valuable tool for such researchers. READ MORE

  5. 4. Characteristics of instream wood following alluvial river restoration : Using Uncrewed Aerial Vehicles

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Martina Fjällberg; [2023]
    Keywords : River restoration; instream wood; uncrewed aerial vehicles; fluvial geomorphology.;

    Abstract : River restoration is something that is often used to help restore watercourses that were historically used for timber floating. In these restorations, instream wood (IW) plays a big role in increasing biodiversity and habitat heterogeneity in watercourses. READ MORE

  6. 5. Synchronized assessment ofcompression of corrugatedboard : Mechanics and visualization

    University essay from Uppsala universitet/Tillämpad mekanik

    Author : Johan Bürger; [2023]
    Keywords : corrugated board; compression; image analysis; thresholding; modelling; Maxwell; spring dashpot;

    Abstract : Flexographic printing involves driving a paper substrate through the gap between two cylinders, where one of the cylinders has a print form layer covered in ink. The ink transfer from the print form to the paper is dependent on the pressure between the paper substrate and the cylinders. READ MORE
