I hope they start imaging at least parts of the ocean, like the great pacific garbage patch and other areas of particular interest for meteorologists and environmentalists.
- rootusrootus 7y agoI thought the garbage patch is not visible to the naked eye, mostly made up of microscopic particles, and especially not to a satellite with a 3m resolution?
- jayess 7y agoThat's correct, it's something like four particles per cubic meter. > "fingernail-sized or smaller bits of plastic", often microscopic https://en.wikipedia.org/wiki/Great_Pacific_garbage_patch https://en.wikipedia.org/wiki/Great_Pacific_garbage_patch
- kleer001 7y agoI imagine it should still slightly alter the appearance of the water. Check out "Eulerian Video Magnification" for more.
- schoen 7y agoThat work is awesome, but don't they need changes over time in order to achieve the magnification? How would you get changes over time with the plastic pollution in order to view it this way?
- kleer001 7y agoUse frames from the same area over a span of time.... What's confusing? There's a picture taken every day. If you're worried about the time span between the frames, I'm certain that shouldn't matter to the algorithm, it's just more noise and maybe the result takes longer to get..
