Computer-implemented method for segmenting measurement data from a measurement of an object

Computer-implemented method for segmenting measurement data from a measurement of an object, wherein the object has at least one material transition region, wherein the measurement data are used to generate a digital object representation having the at least one material transition region, wherein the digital object representation has a multiplicity of spatially resolved image information items relating to the object, wherein the method has the following steps of:

• determining the measurement data, wherein the measurement data have at least one small structure having an extent which is less than a predefined extent;
• determining at least two homogeneous regions in the measurement data and/or in the digital object representation, wherein at least one of the at least two homogeneous regions has a small structure;
• creating a label field which defines the homogeneous regions by means of spatially resolved label values in the measurement data and/or the digital object representation;
• wherein a spatial resolution of the label field is higher than a spatial resolution of the measurement data at least in predefined regions of the object representation,
• wherein the spatial resolution of the label field is at most as high as the spatial resolution of the measurement data in the remaining regions of the object representation;
• analysing a local similarity of the multiplicity of spatially resolved image information items;
• adapting an extent of each homogeneous region until at least one border region of each homogeneous region is arranged at an expected position of a material transition region;
• and
• segmenting the digital object representation on the basis of the adapted homogeneous regions.
