This Algorithm Can Remove the Water from Underwater Photos, and the Results are Incredible

An engineer has developed a computer program that can, in her words, “remove the water” from an underwater photograph. The result is a “physically accurate” image with all of the vibrance, saturation and color of a regular landscape photo.

The technology, called Sea-thru, was developed by oceanographer and engineer Derya Akkaynak while she was a post-doctoral fellow under Tali Treibitz at the University of Haifa, and it has the potential to revolutionize underwater photography. While “remove the water” isn’t the most scientific explanation for how the technology works, as you can see in the Scientific American feature above, that’s more or less what it does.

By automatically removing the color cast and backscatter caused by the way light moves through a body of water, she’s able to capture underwater landscapes as they would look to the human eye on dry land—in other words: if all the water were gone.

Apple trækker farlig computer tilbage

15-tommers udgave af MacBook Pro risikerer at overophede og bryde i brand

Hvis du har købt en MacBook Pro, der er solgt mellem september 2015 og februar 2017, er der god grund til at få den tjekket.
Apple har netop tilbagetrukket modellen, der er solgt i denne periode, fordi batteriet i nogle af enhederne har vist sig at kunne overophede og i værste fald bryde i brand.

Skiftes gratis
Hvis din computer er ramt af fejlen, kan du gratis få batteriet udskiftet. Man kan tjekke, om ens computer er omfattet, ved at indtaste dens serienummer på hjemmesiden her.
Ifølge Apple er der tale om et begrænset antal computere, som udgør en fare. Og det problematiske batteri sidder alene i denne udgave af den 15 tommer store MacBook Pro, understreger firmaet.
Det tager i øvrigt op til tre uger at få sat et nyt batteri i.
