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

    Author : Gustaf Kylberg; Ida-Maria Sintorn; Gunilla Borgefors; Walter Kropatsch; Uppsala universitet; []
    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

  4. 2. Automated Tissue Image Analysis Using Pattern Recognition

    Author : Jimmy Azar; Anders Hast; Ewert Bengtsson; Martin Simonsson; Marco Loog; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tissue image analysis; pattern recognition; digital histopathology; immunohistochemistry; paired antibodies; histological stain evaluation; Computerized Image Processing; Datoriserad bildbehandling;

    Abstract : Automated tissue image analysis aims to develop algorithms for a variety of histological applications. This has important implications in the diagnostic grading of cancer such as in breast and prostate tissue, as well as in the quantification of prognostic and predictive biomarkers that may help assess the risk of recurrence and the responsiveness of tumors to endocrine therapy.

  5. 3. Image Analysis Methods and Tools for Digital Histopathology Applications Relevant to Breast Cancer Diagnosis

    Author : Andreas Kårsnäs; Robin Strand; Carolina Wählby; Ewert Bengtsson; Anant Madabhushi; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; image analysis; breast cancer diagnosis; digital histopathology; immunohistochemistry; biomarker quantification; Computerized Image Processing; Datoriserad bildbehandling;

    Abstract : In 2012, more than 1.6 million new cases of breast cancer were diagnosed and about half a million women died of breast cancer. The incidence has increased in the developing world. The mortality, however, has decreased. READ MORE

  6. 4. Multichannel Audio Signal Processing : Room Correction and Sound Perception

    Author : Adrian Bahne; Anders Ahlén; Lars-Johan Brännmark; Mathias Johansson; Peter Händel; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Audio signal processing; multichannel sound reproduction; equalizers; human sound perception; room correction; Elektroteknik med inriktning mot signalbehandling; Electrical Engineering with specialization in Signal Processing;

    Abstract : This thesis concerns and combines multichannel sound reproduction, digital room correction, audio signal processing, and human sound perception. It investigates perceived sound quality and new methods to improve timbral and spatial fidelity of loudspeaker-based multichannel sound reproduction in reverberant environments. READ MORE

  7. 5. Analysis of Human Brain MRI : Contributions to Regional Volume Studies

    Author : Richard Nordenskjöld; Joel Kullberg; Elna-Marie Larsson; Lars Johansson; Håkan Ahlström; Göran Starck; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MRI; Brain; Volume; Hemisphere; Intracranial volume; Image analysis; Computerized Image Analysis; Datoriserad bildanalys;

    Abstract : Many disorders are associated with regional brain volumes. The analysis of these volumes from MR images often requires sequential processing steps such as localization and delineation. READ MORE
