Abstract: The invention relates to a method for determining a state evolution of a real system with a plurality N of degrees of freedom, comprising the following steps: determining states for each of the plurality N of degrees of freedom up to a time t0, wherein the determining of states for each of the plurality N of degrees of freedom is carried out by measuring corresponding state variables of the real system; selecting a degree of freedom f from the plurality N of degrees of freedom; determining a measure of similarity between the selected degree of freedom f and each other degree of freedom of the plurality N of degrees of freedom of the real system for the determined states; determining a selection M of degrees of freedom from the plurality N of degrees of freedom based on the measure of similarity; and determining the state evolution of measured states for the selected degree of freedom f based on the selection M of degrees of freedom.

Abstract: In order to segment a distribution of points into partial areas with predetermined structural elements, a feature vector ({right arrow over (x)}i) whose components are determined based on several scaling factors is ascertained for each point ({right arrow over (p)}i); the accompanying feature vectors ({right arrow over (p)}il) are determined for a predetermined number of reference points ({right arrow over (p)}il) for which the respective allocation to one of the structural elements is given, and texture classes each corresponding to the underlying structural elements are formed out of the feature vectors of the reference points; a distance to each of the texture classes is determined for all remaining points ({right arrow over (p)}iu) of the point distribution that are not reference points ({right arrow over (p)}iu); and the partial areas of the segmentation are formed out of the reference points respectively belonging to a texture class and the allocated points.
