Algorithm that removes the water from underwater images

However first you say it's similar to taking sand as a point for WB, and that's simply not correct. Even if you could accomplish more or less the same by accident using Photoshop and whatnot, it still does not make it the same. It only illustrates you're missing the point.

Is there a point?

Yes, that it's not the same.

Seems to be a lot of whining for a guy who also proclaims to not care.

If I feel like it I reply. And it seems to me, you do the whining by criticizing without understanding. By complaining about words being chosen, al-go-rithm, yes that's what it's called. By asking for a paper and then ignoring it. By accusing a researcher of self promotion, setting of your BS meter while most of the BS comes from you.

Color correcting for depth and lighting is the point. Sand, skin, and sometimes the tank can serve as a substitute for the grey card

See? You still don't get it. Also it does not require a card.

, and then the photographer can adjust as subjectively appropriate. It's fairly simple, works now, and works with one shot.

Yes. no one argues that. No one claims you can or should throw that overboard.

As someone who spends much more time shooting moving objects, one shot is important. Shooting a coral reef every 4 months to watch trends - might be able to work with the requirements.

Yes, sure. So? IOW, it's not for you. Okay.

I will remain skeptical that there is a 'correct' color result.

Maybe write your own paper then.

Going past the obvious variability in the environment and the lighting used, even the camera sensors vary. Canon colors vs Sony's shadow pulling.

You didn't even glance at the paper you asked for, did you? The researchers admit to that, but it's also data that can be fed to the model.

Progress comes when there is a repeatable (by others) experiment. We're not there here.

The progress is there no matter how you try to frame it. A first step is already progress even if the method would proven to be wrong at a later point.

I would have imagined me being a marine photographer, being interested in this type of developments whether it is useful for you right away or not.
