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

    Author : Amalka Pinidiyaarachchi; Carolina Wählby; Ewert Bengtsson; Arvid Lundervold; Uppsala universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 2. Quantitative image analysis : a focus on automated characterization of structures in optical microscopy of iron ore pellets

    Author : Frida Nellros; Carolina Wählby; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Signal Processing;

    Abstract : Sintering occurs in many types of material such as iron, ceramics and snow, typically during thermal treatment, and aects the material properties, particularly the strength, by the bonding of particles into a coherent structure. In order to improve the mechanical strength in magnetite iron ore pellets it is important to be able to characterize and quantitatively measure the degree of sintering and features that impact the process of sintering.

  5. 3. Segmentation Methods for Medical Image Analysis : Blood vessels, multi-scale filtering and level set methods

    Author : Gunnar Läthén; Reiner Lenz; Niels Christian Overgaard; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Image segmentation; Medical image analysis; Level set method; Quadrature filter; Multi-scale; Image analysis; Bildanalys;

    Abstract : Image segmentation is the problem of partitioning an image into meaningful parts, often consisting of an object and background. As an important part of many imaging applications, e.g. face recognition, tracking of moving cars and people etc, it is of general interest to design robust and fast segmentation algorithms.
