I am a newbie in image processing domain; I would like to ask for your views over a problem I encounter.

This is an example image.

What I want to get after segmentation are objects which are two coins, words front and back.

What I have done :

do binarisation
finds connected components
create mask for correspond to the object
use regionprops to get areas and get only those who are bigger than certain amount ....

I can get those objects;however, I have hard time to determine when there are others images that have different size and distance between coins n texts.

Could you share your views how we cleanly segment the objects?

Thank you so much

What text are you talking about? "Front" and "Back"? "Challenge Coins Plus" in the background, or the text on the coins themselves? And I don't know what you're trying to measure. Do you want to do OCR on the text? Do you want the area of the coins? Do you want to identify what kind of coin it is? I have no idea. All you said was " I have hard time to determine when..." But determine what???? Area? Coin type?
