Dang, that’s not easy. Here’s a typical image that I was presented;
I did a dozen or so of them, and only a couple were a clear “No” (no ship or ship-debris-like object present). Two or three more were so noisy as to make the job impossible, so I “returned” them. The others involved more time than you’d expect, and a lot of squinting.
A technique that I found useful was to tilt my laptop display backwards which seemed to perform a low-pass filter of sorts, reducing noise and making it easier to identify objects. Maybe that would work for you too. My display is TFT.
It’s a tough job, but I’m happy to help.
Update; the images are a lot clearer today. I’m zipping through them.
