Structure quantification via Minkowski functionals. a) Counts map, simulated Poisson-distributed random number of counts k. To characterize the morphology, the image is turned into a black-and-white image via thresholding – see b); the three Minkowski functionals are then evaluated for the b/w image. b) Area A. c) Perimeter P. d) Euler characteristic χ.
