What's the difference? Do you _need_ to convert? If yes, probably one
or more suitable transformation matrices will help.

mosaicing rolled pictures (with overlap) form the final dab
fingerprint. in fact a Delta value between each two neighbor pictures
(frame of camera) can be calculated.

Mosaicing? I don't know whether I understood you correctly, but if it's
your goal to reduce false positives by reducing detail, you're doing
something wrong. If not, what are you trying to achieve?
