title: An integral-geometric approach for the euler-Poincare characteristic of spatial images
abstract: The determination of the Euler-Poincare characteristic of a set can be based on observations of a digitized image of that set. In the present paper the correctness of the method is proved due to a strict integral-geometric approach. Our result also provides a link to the methods which are used in image analysis and are based on graph theory.
