描述
算子 distance_rr_mindistance_rr_minDistanceRrMinDistanceRrMinDistanceRrMindistance_rr_min calculates the minimum distance
of pairs of regions. If several regions are passed in
Regions1Regions1Regions1Regions1regions1regions_1 and Regions2Regions2Regions2Regions2regions2regions_2 the distance between the
contour pixels of each i-th element is calculated and then forms the
i-th entry in the output parameter MinDistanceMinDistanceMinDistanceMinDistanceminDistancemin_distance. The
Euclidean distance is used. The parameters (Row1Row1Row1Row1row1row_1,
Column1Column1Column1Column1column1column_1) and (Row2Row2Row2Row2row2row_2, Column2Column2Column2Column2column2column_2) indicate
the position on the contour of Regions1Regions1Regions1Regions1regions1regions_1 and
Regions2Regions2Regions2Regions2regions2regions_2, respectively, that have the minimum distance.
The calculation is carried out by comparing all contour pixels (see
get_region_contourget_region_contourGetRegionContourGetRegionContourGetRegionContourget_region_contour). This means in particular that
holes in the regions are ignored. Furthermore, it is not checked
whether one region lies completely within the other region. In this
case, a minimum distance > 0 is returned. It is also not checked
whether both regions contain a nonempty intersection. In the latter
case, a minimum distance of 0 or > 0 can be returned, depending on
whether the contours of the regions contain a common point or not.
注意
Both input parameters must contain the same number of regions. The
regions must not be empty.
