OK, this is clear now.

I have met term ROI mostly used to describe a certain coding strategy
where regions which are encoded to higher quality (and stored as such in
a format) than the rest of image. This is common technique used in
JPEG2000 or PGF. This also allows faster decoding and access to
those subimages where each of them is ROI.

I just wanted to confirm that we think of the same writing and
reading the term ROI.
