描述

算子 distance_rr_min_dildistance_rr_min_dilDistanceRrMinDilDistanceRrMinDilDistanceRrMinDildistance_rr_min_dil calculates the minimum distance between pairs of regions, by iteratively applying dilations on both regions until their intersection is non empty. If several regions are passed in Regions1Regions1Regions1Regions1regions1regions_1 and Regions2Regions2Regions2Regions2regions2regions_2 the distance between the i-th elements in each case is calculated. It then forms the i-th entry in the output parameter MinDistanceMinDistanceMinDistanceMinDistanceminDistancemin_distance. The calculation is carried out with the help of dilation with the Golay element 'h'"h""h""h""h""h" (see dilation_golaydilation_golayDilationGolayDilationGolayDilationGolaydilation_golay for further information). The result is: where is the number of iterations. The mask 'h'"h""h""h""h""h" has the effect that precisely the maximum metrics are calculated.

注意

Both parameters must contain the same number of regions. The regions must not be empty.
