Hi: 

Has anyone implemented following features extraction routines?.
These features are mentioned in Pratt's Image processing book on page 646.
He has a reference to this which is unpublished Stanford Research Institute'
Notes. Has anyone implemented these or know of any place I can get hold 
of routines which can do following things.


1) The smallest rectangle oriented along the major axis of 
   the object that encompasses the object (Object oriented bounding box)
                                           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
2) dimensions of object oriented box, width, height

3) the minimum and maximum distance between the centroid and a 
   perimeter pixel

4) The angle of the minimum and maximum radius vector with respect 
  to the horizontal axis

5) ratio of min radius angle to max radius angle.

Out of the above 1-4 are not difficult to implement but the object
oriented rectangles are the ones i am looking for.
