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

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Gustaf Kylberg; Uppsala universitet.; Uppsala universitet.; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; image analysis; image processing; virus identification; transmission electron microscopy; texture analysis; texture descriptors; Computerized Image Processing; Datoriserad bildbehandling;

    Abstract : 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. READ MORE

  2. 2. Dynamic Programming for Ultrasound Image Analysis of Atherosclerosis

    University dissertation from Chalmers University of Technology

    Author : Peter Holdfeldt; Chalmers tekniska högskola.; Chalmers University of Technology.; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bildanalys; Image analysis; atherosclerotic plaque; carotid artery; classification; dynamic programming; edge detection; graph cuts; image analysis; ultrasound;

    Abstract : Cardiovascular diseases, due to atherosclerosis, are among the most common causes of death in the industrialized world. Atherosclerotic plaque composition as well as arterial diameter and wall thickness can be used to predict the risk of cardiovascular disease. These risk factors can be assessed non-invasively by ultrasound. READ MORE

  3. 3. Live Single Cell Imaging and Analysis Using Microfluidic Devices

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Mohammad Ali Khorshidi; KTH.; [2013]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Single cell analysis; time-lapse fluorescence imaging; automated image analysis; microwell; droplet microfluidics; NK cells; single cell tracking; migration behavior analysis; cell-cell interaction; optical microscopy; image analysis; image processing; microfluidics; immune cells; tracking; counting; morphology analysis;

    Abstract : Today many cell biological techniques study large cell populations where an average estimate of individual cells’ behavior is observed. On the other hand, single cell analysis is required for studying functional heterogeneities between cells within populations. READ MORE

  4. 4. Image Filtering Methods for Biomedical Applications

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : M. Khalid Khan Niazi; Uppsala universitet.; Uppsala universitet.; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Digital image analysis; Image filtering; Intensity inhomogeneity correction; Empirical mode decomposition; Particle Swarm optimization; Image registration; Computerized Image Processing; Datoriserad bildbehandling;

    Abstract : Filtering is a key step in digital image processing and analysis. It is mainly used for amplification or attenuation of some frequencies depending on the nature of the application. Filtering can either be performed in the spatial domain or in a transformed domain. READ MORE

  5. 5. Image Analysis in Support of Computer-Assisted Cervical Cancer Screening

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Patrik Malm; Uppsala universitet.; Uppsala universitet.; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Image analysis; cervical cancer; pap-smear; synthetic images; screening; image processing; cytometry; Computerized Image Processing; Datoriserad bildbehandling;

    Abstract : Cervical cancer is a disease that annually claims the lives of over a quarter of a million women. A substantial number of these deaths could be prevented if population wide cancer screening, based on the Papanicolaou test, were globally available. The Papanicolaou test involves a visual review of cellular material obtained from the uterine cervix. READ MORE
