How to merge nearest boudingbox from regionprops in matlab

I am a newbie in Matlab.

I have an image, let's say,

http://smallwarsjournal.com/sites/default/files/swjoldfiles/images/coin1.jpg

I want to do segmentation all the objects from the image, coin and text.

I can get all the object using Bounding box of regionprops; I could get coins and each characters.

*However, what I want is not each characters but if the characters are near to each other let say '7 AU' I want to get a boundingbox of this so I could crop an image 7 AU.

What I think right now is to merge the bounding box of the nearest object or characters.*

Maybe there are other ways, What do you think?

If the question is not clear drop your question I will answer it as soon as possible..

Thank

Dilate the mask ( imdilate ) the acceptable "closeness" distance first so that the objects touch, then use regionprops.

Thank for your answer.

Could you explain a bit more?

What i get so far is the image with background white and objects are black, so If I use the imdilate some small characters will be white and the regionprops could not be detected, and I cannot get the bounding-box of those small characters.
