It is not really possible to remove artifacts from images because there is a degree of randomness in which photons arrive, and even if your model is accurate down to the level of QED, you will not be able to exactly subtract the photon counts.
- s1artibartfast 5y agoIm not sure I follow. Im not saying that you subtract photon counts, but void measurements entirely for pixels with satellites in them.
- whatshisface 5y agoTelescopes use long exposures. The satellites leave streaks and a lot of pixels would have to be deleted.
- postalrat 5y agoMaybe two telescopes and a bit of math to use the difference in distance to the satellites vs the asteroids?
- s1artibartfast 5y agoLong exposures can still have a duration censored. This is digital photography, not chemical. If you expose for 1 million seconds, you can edit out 60 seconds where a satellite passes. That data is forever gone, but you still get the rest of the data from that pixel time.
- mhh__ 5y agoGiven that the earth rotates every 1.5 thousand or so minutes something tells me 1 million may not be representative...
- s1artibartfast 5y agoSure, I was being extreme, but multi day or week surveys exits. In fact, they already have to do a lot of filtering to remove transient artifacts
- nieve 5y agoYou're assuming there's only one satellite to worry about per exposure.
