Consider an image of a "Go" board. Are the "individual objects" the squares,
or the lines?

In the famous optical illusion, is the object to be recognized the Young Lady,
or is it the Old Woman?

In another famous optical illusion, are the objects to be recognized a pair of
faces, or a single chalice ?

In a picture of the Sun, are the objects to be recognized the solar limba, or
are the objects to be recognized the sun-spots ?


When you can answer these questions in terms of *objective* criteria about
what part of an image is an "object" and what part is instead "background",
then it might be possible to answer your question. Research to date has not
yet found any such *objective* criteria, but possibly you might be able to
come up with something that others have missed.

at present i am doing clustering of geometrical objects in an image, so i need to do that project specific to the geometric objects, its an experimental type. we are """"giving input as an image with different geometrical objects in it, i had to recognize it and do hierarchical clustering on the basis of data collected from those objects"""...
i will also try what you specified.. for my topic please help me

>>>what part of image is object can be told if there is any contour is emerging from the edge or outline of the image, else except outer frame if we can recognize any closed contour is there then they are objects.. its interesting. now i had to complete my "hierarchical clustering of objects".. if anything related to this help me

You haven't given anyone here enough info to help you in anything more
than the most general case, like what Sean said. If you want more
specific help on image analysis, it helps (OK, it's virtually
essential) to post an image somewhere (an image hosting website of
your choosing). After all, how can we give image processing advice
with an image to look at??? Your two latest comments added no
information whatsoever as far as giving us concrete information to
work with.
