Cropped image with merge bounding boxes

[riccardoregnicoli]

Hi everyone,
I am sorry for bothering, maybe that's a trivial question, but I need to "merge" the bounding boxes detected and save them to an image. I have read this issue (#39 (comment))
but I believe this code allows to save an image for every bounding box
I need an image with more bounding boxes merged.
In other terms, with text "Hello World" on the image, I don't want two different cropped images "Hello" and "World", but only one cropped image with "Hello World"

Any suggestions?

Thank you again!
