hello,
I have a binary image with five objects in it, I've found the distances between each pair, I gonna find the x-y coordinates of the two objects which have the special distances (for example the biggest distances), how can I do that? Thank you for your help in advance.

With PairWiseDistanceArray being your 5 x 5 distance array where the index (I,J) is the distance between object #I and object #J, then:
[maxdistance, maxidx] = max(PairWiseDistanceArray(:));
[object1idx, object2idx] = ind2sub(size(PairWiseDistanceArray),maxidx);
The maximum distance was maxdistance and it was between object #object1idx and object #object2idx

obj1 and obj2 are not the x and y coordinates, they are the object number.
xp1 = centrex(obj1);
xp2 = centrex(obj2);
yp1 = centreY(obj1);
yp2 = centreY(obj2);
