Abstract: In a method and an apparatus for detecting various cells types of cells in a biological sample, an image of the biological sample is provided. This image is normalized with regard to a distribution of the image values, and the normalized image is subsequently divided into a plurality of image sections. Each image section is associated with a predetermined class in dependence on predetermined properties of the image section. In each image section, the individual cells are detected, and features of these individual cells are determined. Subsequently, the individual cells are associated with a specific cell type on the basis of the features detected.

Abstract: In a method for extracting texture features from a multichannel image, which comprises a plurality of pixels, information of at least two channels of the image is combined for each of the plurality of pixels, and one or several texture features are determined from the combined pixel information.

Abstract: In a method for separating a cell group contained in an image of a sample into individual cells for a subsequent classification of the sample, wherein the cell group has a plurality of mutually overlapping cells, first a cell nucleus of a first cell which is to be separated from the cell group is selected, wherein the cell nucleus is located adjacent to a cell nucleus of a second cell. The cell plasma of the first cell and the cell plasma of the second cell overlap such that a common cell plasma is formed. Subsequently, a contraction of the common cell plasma between the cell nucleus of the first cell and the cell nucleus of the second cell is determined. At the contraction, a separation of the common cell plasma is performed. Subsequently, an area of the common cell plasma is determined in which the overlapping of the cell plasmas of the two cells is expected.
