  • Disector program for unbiased estimation of particle number, numerical density and mean volume
    Tomori, Zoltán ; Krekule, Ivan ; Kubínová, Lucie
    A DISECTOR program is presented, offering the possibility to count particles by the disector or unbiased sampling brick principles as well as to apply the point-counting method needed for estimation ... of the particle volume density or mean particle volume. Three modes of counting, two semi-automatic and one automatic, are offered, allowing the user to choose the one most suitable for his image data. In a semi-automatic regime, the user marks and counts individual particles by a mouse during browsing through the stack of images. In the algorithm working in an automated mode, the role of a human operator issuppressed, assuming that segmented objects are available in individual levels. The settings of the point grid and 3-D probe can be tailored for each application. The DISECTOR program applications are shown on the examples of the estimation of the numbe and numeical density of mesophyll cells in a Norway spruce needle and the mean volume of tubular cells in a chick embryonickidney.
