how to find mid point between two centroids of objects?

3 views (last 30 days)
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.
