Hi folks. I have been analyzing the code and trying to understand what
ImageSegment does and how. After that, I came up to SmartRefStream and here
is where I have some questions:

1) which is the difference between ImageSegment and SmartRefStream ? what
does each of them do ?

2) Who uses who ? ImageSegment uses SmartRefStream or vice-versa?  each one
use the other?

Thank you for any hints you can give me.

Mariano
