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. Multiple-Emitter Super-resolution Imaging using the Alternating Descent Conditional Gradient Method

   University essay from Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

   Author : Dolev Illouz; [2023]
   Keywords : super-resolution; alternating descent conditional gradient method; ADCG; multiple-emitter localization; nanoscale imaging; single molecule tracking; Physics and Astronomy;

   Abstract : This thesis examines the state-of-the-art 2D super-resolution technique alternating descent conditional gradient (ADCG) method's ability to accurately localize fluorophores in diffraction-limited single molecule images (SMI) and analyze the impact of pre-processing and post-processing modules on ADCG's fluorophore localization. A synthetic dataset obtained from the 2013 Grand Challenge localization microscopy and a temporally linked dataset obtained from an unpublished set of Optical DNA mapping experiments performed by Jonathan Jeffet at the NanoBioPhotonix Lab at Tel-Aviv University were initially segmented to extract their noise parameters.

4. 3. Increased system sensitivity using fluorescent based immunoassays on the Gyrolab® platform

   University essay from Uppsala universitet/Institutionen för farmaci

   Author : Gabriel Lisra; [2023]
   Keywords : Gyrolab; fluorescence; sensitivity; immunoassays;

   Abstract : Immunoassays have become an essential tool in several fields of bioanalytics with tremendous advances in sensitivity and formats seen through the last three decades. Many diseases are today diagnosed solely based on biomarker concentrations evaluated through immunoassays. READ MORE

5. 4. Quantification of DNA Nanoballs Using Image Processing Techniques

   University essay from Uppsala universitet/Avdelningen Vi3

   Author : Sara Lindberg; [2023]
   Keywords : image analysis; fluorescence microscopy; quantification; DNA; rolling circle amplification; machine learning; deep learning; transfer learning; neural networks;

   Abstract : In gene editing, it is important to identify the number of edited and unedited nucleic acids in the development of new therapies and drugs. Countagen is developing a technology for accelerating genomic research and their product is called GeneAbacus. READ MORE

6. 5. 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
