How do I merge multiple bounding boxes that overlap into one bigger bounding box?

Hello,

I am trying to detect text from an image (Magic Card) and I managed to create bounding boxes for each of the the candidate characters. However, I would like to merge all overlapping boxes as one larger box for optical character recognition. Is there a way to do this? Below is an image of the bounding boxes I currently have:

Hi,

this example proposes a method to merge boxes, using "accumarray":

This doesn't quite help. I actually already know which boxes overlap but have not figured out exactly a way to connect the individual boxes.
