This researcher created an algorithm that removes the water from underwater images

Why do all the pictures you take underwater look blandly blue-green? The answer has to do with how light travels through water. Derya Akkaynak, an oceangoing engineer from the University of Haifa, has figured out a way to recover the colorful brilliance of the deep.

  • Instagram has this "algorithm" built in already since long ago, but they named it "filters" rather than "see through" 😂

  • Nice. If you can create a training set of a couple thousand images we can train a neural network to do a very passable job on images without the colorchecker in the image.

  • The most weird thing about this is, that this actually only came up now. In 2019. O.o How the hell didn't adobe invest in this kind of thing. Seems so easy. Of course, considering you know what you are doing. Amazing idea. Hope she will get paid for this enough and not being bought by adobe or others.

  • So, the chart with known color values is put in frame to provide the algorithm with the info needed to "back out" the effects of diffusion. It's (in effect) the same as using a sheet of clean white paper to reset the white balance on a DSLR before a photo shoot... just using more colors to finely tune the adjustment. Bravo! Sometimes the best inventions aren't totally new, just a new take or application of an existing idea!

  • This is just color correction, that chart is actually a color checker and is used in filmaking, the computer knows the colors of that chart so when you upload the image to the program, it kind of automatically matches the colors of the image to the colors of the chart, thats why the images is corrected that way.

    • @gracefool The video is not clear in many aspects, which leads to simplistic interpretations. And the actual scientific paper on the method is too complex for most people. I don't understand half of it, but I'm pretty sure it's not even close to anything we do with Photoshop or Lightroom :)

    • @KK Foto good point, it uses distance too. If she's really just using the color palette for checking, then cool - it doesn't seem clear from the video.

      gracefoolgracefool10 gün önce
    • All them silly scientists are no match for you guys. The method uses photogrammetry to implement a pixel by pixel distance dependent correction that includes scattering parameters and color attenuation. The color chart plays no role in the process. It is used only to check the results.

  • Very interesting. Could you also use the same algorithm and source images to generate an image of only the water? Then if you had other information such as the distance at any given spot in the image, you could then derive information about the composition of the water.
