1. 1. Automatic Virus Identification using TEM : Image Segmentation and Texture Analysis

   Författare :Gustaf Kylberg; Ida-Maria Sintorn; Gunilla Borgefors; Walter Kropatsch; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; image analysis; image processing; virus identification; transmission electron microscopy; texture analysis; texture descriptors; Computerized Image Processing; Datoriserad bildbehandling;

   Sammanfattning : Viruses and their morphology have been detected and studied with electron microscopy (EM) since the end of the 1930s. The technique has been vital for the discovery of new viruses and in establishing the virus taxonomy. Today, electron microscopy is an important technique in clinical diagnostics. LÄS MER

3. 2. Correlating Microstructure with Texture of Particulate Biopolymer Gels

   Författare :Maud Langton; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; microstructure; image analysis; texture; electron microscopy; lactoglobulin; particulate gels; whey protein; light microscopy;

   Sammanfattning : The microstructure of particulate biopolymer gels has been studied to comprehend the effect of microstructure on textural properties. Particulate structures have been characterized at different levels by using light microscopy, scanning electron microscopy, and transmission electron microscopy. LÄS MER

4. 3. Texture and color of potato products

   Författare :Sandra Segnini; Livsmedelsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; potato processing; sensory evaluations; L*a*b*; French fries; potato chips; Texture; color; Food and drink technology; Livsmedelsteknik;

   Sammanfattning : Texture and color are the most important parameters in the definition of the quality of potato products, but usually their subjective measurements do not give any reproducible results due to the complicating factors related to human perception. In order to understand the factors that can affect the texture and the color of the potato products during processing, instrumental techniques have been developed for quantifying those parameters.

5. 4. Digital Image Analysis of Cells : Applications in 2D, 3D and Time

   Författare :Amalka Pinidiyaarachchi; Carolina Wählby; Ewert Bengtsson; Arvid Lundervold; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Digital image analysis; microscopy; fluorescent staining; watershed segmentation; sub-cellular localization; point-like signals; wavelets; cell confluence; cytology; color spaces.; Image analysis; Bildanalys;

   Sammanfattning : Light microscopes are essential research tools in biology and medicine. Cell and tissue staining methods have improved immensely over the years and microscopes are now equipped with digital image acquisition capabilities. The image data produced require development of specialized analysis methods. LÄS MER

7. 5. Development of new MRl-based analysis methods for improved diagnosis of low back pain patients

   Författare :Christian Waldenberg; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; annular fissure; bone marrow lesion; image analysis; intervertebral disc; intervertebral disc degeneration; low back pain; machine learning; radiomics; texture analysis;

   Sammanfattning : BACKGROUND Low back pain (LBP) is the leading cause of disability worldwide, where three of four individuals experience back pain at some point in their lives. The pathophysiological background of LBP is probably multifactorial, where bone marrow damage, tissue changes in the vertebral endplates, and intervertebral disc (IVD) degeneration have been recognized as tissue changes linked to pain.
