Is there an exposure or cleaning scans batch plugin?

[moris]

I need to clean photos of documents batch-wise. I like the exposure plugin for this but it's not supported in Bimp. Is there a way to add it to it? To script it? Or could you recommend me another batch plugin for this purpose?

I've tried levelss and Sharp but both gave mediocre results.

Thanks for any help.
