MATLAB: How to find mid point between two centroids of objects

Question

hello friends,

I want to find mid points between two centroids of objects.

I have used this code :

for n=1:Ne 
[r,c] = find(L==n);
s  = regionprops(L, 'centroid');
centroids = cat(1, s.Centroid);
imshow(image);
hold on
plot(centroids(:,1), centroids(:,2), 'b*');

I found the result as

This code gives the centroids from the corner points too. which are unnecessary. how to remove them?

I would be thankful if someone helps me to find mid point between two two centroids of objects by finding the distance between them or else.

thanks in advance.
