Definitions
- Fig. 1 shows an input data set or the recorded areas.
- a labeling unit 12 is connected to the output of the correlator or multiplier 11, in which the outputs of the multiplier 11 corresponding to the less restrictive mask are made with respect to the determination of the local gray values of each of the locally limited areas or clusters and the average gray values of the respective areas are determined.
- the obtained gray values in each cluster undergo discrimination with a predetermined threshold. This gives a restrictive mask.
- a growing unit 14 growth takes place starting from the individual segmentation starting points in the region of the restrictive mask and at most one following growth of these areas in the less restrictive mask and optionally subsequently in the foreground mask, wherein the data sets concerning the restrictive mask are supplied by the labeling unit 12 and the data sets concerning the less restrictive mask are supplied by the multiplier 11 and the discriminator 3, respectively, to the growing unit 14.
- cell preparations in particular cell sections, are stained in order to identify the cell nuclei differently from the remaining cell components.
- the cell nuclei or the nuclear agglomerates have a different coloration to the remaining cell constituents or the image background or other constituents contained in the tissue section, and can be localized in the recorded image.
- the image there is the uncertainty that in cell nuclear agglomerates the cell nuclei are covered or not reproduced in their entirety, or the brightness ranges do not have sharp boundaries or brightness values that are not easily distinguishable, ie. Color values or gray values are present. This should be counteracted according to the invention. From the image area to be examined of a tissue preparation or
- the segmented input data is visually, e.g. printed on a screen or printed or possibly stored with the calculated parameters.
- the threshold values are selected according to the desired accuracy or the desired data separation and are to be specified.
- the provided correlation methods may e.g. in a weighted addition of the data or in a multiplication, possibly also in a division or other combination of the data, exist, as long as a corresponding increased distinctness of the data with the correlation is achieved.
