Abstract: A method for detecting geometrical structures in images, especially in images of chemical and/or biological samples, such as images of cells, the method comprising the following steps: detecting a boundary line of the image object; defining at least one sector inside the image, the origin (pk) of which lies on the boundary line; transforming the image section defined by the sector into a transformation space by means of a transformation that associates signatures in the transformation space with respective geometrical structures in the image section; determining the presence of at least one signature inside the transformation space; and retransforming the signatures from the transformation space into the sector for the representation of the geometrical structure.

Abstract: An optical measurement device for measurement of chemical and/or biological samples comprises an illumination means (16) for illuminating the sample (20) to be measured. Further, an optics means (22) is provided for imaging a sample area in an image field (10). A first partial area (12) of the image field is covered by a first detector (28), and a second partial area (14) of the image field (10) is covered by a second detector (34). Thus, it is possible to change between two measurement methods without switching or to perform two measurements on a sample at the same time.

Abstract: A method for analyzing chemical and/or biological samples comprises the production of a particle image (42) of at least one particle included in the sample. Subsequently, a particle surface (10) of the at least one particle included in the particle image (42) is divided into particle zones (14,18). According to the invention, zone-dependent particle data are subsequently acquired in different states (z1, z2, z3), which then can be evaluated.
