NASA scientists have demonstrated FluidCam as a drone based solution to provide sharp, clear imagery of coral reefs from a drone's eye view.

Watch the video, write your own transcripts, summaries and criticisms in the comments. It's image processing, it's drone based, they're working toward making it satellite based. I want to know how well it deals with moving objects in the field of view (like fish), but now that the reefs are mostly dead or dying I guess there aren't that many fish on them to worry about anymore? There certainly weren't any fish in the pictures on the video.

Bonus points to the first comment that links to some hard science papers on the topic, the link above is just a NASA "gee isn't this cool" video.

    This development is of limited usefulness because bedroom walls are not "wavy surfaces". -- Zukerbooger

    Any relation to the transform(s) used when Google Books scanned books without flattening the pages (to preserve old bindings)? They did something clever to transform the photo of the curved surface to be a flat scan suitable for OCR or just display.

    Nude beaches have wavy water surfaces.

    There used to be some weird Zerohedge metaphor from a decade ago about people looking wrinkly and gross when the water recedes or something.

    Have you ever seen those windows with wavy glass surface installed at bathrooms in order to let light in, but prevent looking through?

    Well, here we have a technique that undoes the effect of transparent media with wavy surfaces …

      Glass block windows into showers were a very 80s thing, now considered as dated as shag carpet. I guess they're transparent now, with a little computational effort.
