Hi,

You can do both with the classes in this contribution, which are now  
in ITK:

   http://hdl.handle.net/1926/584

Here is an example (in python):

   import itk
   reader = itk.ImageFileReader.IUC3.New(FileName="foo.nrrd")
   bi2lm = itk.BinaryImageToShapeLabelMapFilter.IUC3LM3.New(reader)
   print bi2lm()[0].GetNumberOfLabelObjects()
   for lo in bi2lm[0]:
     print lo.GetBoundingBox()

You'll find several C++ examples in the link above.

Regards,

Gaëtan
