how can i get the end point coordinates of major, minor axis of a blob

i have calculated major/minor axis length of 5 blobs present in my image . now i need to know the end point coordinates of the major/minor axis how can i do that?

Axismeasurements=regionprops(labeledImage,'MinorAxisLength','MajorAxisLength');

for k=1:numberOfBlobs

      minorAxis=Axismeasurements(k).MinorAxisLength;
      disp(minorAxis);
  end
  majorAxis=Axismeasurements(2).MajorAxisLength;

Use bwmorph with the 'endpoints' option on the label or binary image.

doc bwmorph

I = false(21);
I(10,3:18) = true; %horizontal line
epts = bwmorph(I,'endpoints')
