Abstract

Described is a computer-implemented method for determining material interfaces of an object from at least one measurement of the object, a rasterized representation of the object being produced by means of the measurement, the rasterized representation having a plurality of measurement points, a measurement point having at least one piece of image information, which indicates a value of a measurement variable for the object at the position of the measurement point. The method comprises the determining of a parameterization of the rasterized representation of the object, the parameterization assigning at least one parameter to each of the measurement points of a subset of the measurement points of the representation, and the applying of at least one parameter-dependent edge-detection operator to the measurement points of the rasterized representation, an edge-detection operator being designed to determine the location of at least one material interface in the rasterized representation.
