Techniques to compensate for pits after star removal?
I love the star removal tool to help focus on only the target, but after working a couple of images through, there are very noticeable artifacts that look like pits in the image. These unfortunately stay with the image all through post-processing. I was able to mask/blend some of them with an inpaint/healer tool in Affinity Photo, but that creates its own visual issues, given the number of artifacts, especially in brighter regions of the data.
Is there a good way to deal with these, or perhaps a better practice when removing all the stars? The attached image is the initial stretch of the data once exported from APP as 32-bit float FIPS.
Well, I don't think there is in APP itself other than choosing to reduce stars instead of removal. It's not perfect yet, itis a very difficult thing depending on the data usually (e.g. if there is a very star dense field). We will of course work on improving it.
I've seen the same issue using .83 beta when increasing the threshold setting too much. I just downloaded the most recent version and it seems to work well.
It turns out that the star reduction does leave some artifacts behind, but only at the bottom of the image. This can be cropped out and only affects the bottom 20-30 pixels. Other than this small problem, the star reduction works very well, much better than Startools.
