This researcher created an algorithm that removes the water from underwater images
Here’s a link to the research explaining the algo: http://openaccess.thecvf.com/content_CVPR_2019/papers/Akkaynak_Sea-Thru_A_Method_for_Removing_Water_From_Underwater_Images_CVPR_2019_paper.pdf
could you use this to create a situation where you have cameras on Submarines that run the images thru this algorithm and feeds it into the sub providing a “real-time” clear view of the surrounding area.
or maybe like into a VR helmet. that’d be pretty cool.
I like that this is both a color correction based on a color chart (aka white balance with extra steps) but also she notes that she takes distance into account by getting photos of it as she approaches. This helps adjust for the increased color loss at distances and not just rebalancing while up close.
What interests me is how this can be used in other contexts. Atmospheric mediums can have a wide variety of “impurities” that have the same effect. A color calibration card can be found on the Mars rovers, for example, but it can lose value in a sandstorm. My personal idea is a Venus probe could implement this as a deployed object to help get an idea of the thickness of the atmosphere, etc. Fun stuff. Kudos to her.
This is a marvelous first step in our war against the ocean. I hope one day we can see a world witout oceans at all. That terrible she-devil the sea, what et our seafaring men, our bounties an’ plunder fer thousands o’ yers naught to give a shred o’ it back.
She white balances the ocean.

…and the top rated comment goes to the first person to find an album of all the photos.
Shark week is gonna be dope as fuck next year.
>using a complex algorithm…
oh great here we go

this might be a first.
Hi folks, this is Derya (the researcher in the movie above), known to reddit as torapoop.
Just a clarification: the method does NOT require the use of a color chart. That part was not clear in the video. All you need is multiple images of the scene under natural light, no color chart necessary. For those interested in the exact science, the publication is here:

Ask away any other questions you might have — happy to answer them.
This is easy, it’s just
if (water) {
water = false;
}
So how long until this can be done in real time and AR projected in my diving mask? And will it be while there’s still corals to see?
Her name is Darya. In Farsi it means….. Ocean!!
