As far as I know K. Bouman [0] was the scientist leading the charge on the image processing/reconstruction. A few of her later papers probably have hints [1, 2] about how this is done, but I haven't seen the official release.

- nonbel 8y agoThanks, I think I added the link to the paper while you were writing this. From skimming it I can't tell the answer to my question though. How do they know what appears "black" in the image is really black vs. relatively black?
- LolWolf 8y agoIf you observe a very wide band of light (e.g., EM radiation) and there is nothing received from those spots, then, for all intents and purposes, the region of that image is black. Now, if you're asking if, perhaps, the region isn't really black, but rather it's emitting some sort of small radiation relative to the bright region, it would be essentially impossible to know without much higher resolving powers (since it might even be indistinguishable from the background noise generated by the surrounding region). There is no way to really know if it's "perfectly black" vs. "orders of magnitude darker than the surrounding regions."
- nonbel 8y agoMakes sense. So I guess they could probably tell us an upper bound on how bright it is.
