    Sammanfattning : This thesis, within the subfield of computer science known as computer vision, deals with the use of scale-space analysis in early low-level processing of visual information. The main contributions comprise the following five subjects:The formulation of a scale-space theory for discrete signals. LÄS MER

  3. 2. Segmentation and Tracking Algorithms for in Vitro Cell Migration Analysis

    Författare :Karin Althoff; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This thesis describes a system for automatic in vitro cell migration analysis. Image sequences of adult neural stem/progenitor cells were acquired using a time-lapse bright-field microscopy setup. The adult neural stem/progenitor cell has the ability to differentiate into three different neural lineages; neuronal, astrocytic and oligodendrocytic. LÄS MER
