Niks op aan te merken (en dat gebeurt maar weinig). :) Dank voor het plaatsen van een goede resolutie ook, heerlijk om doorheen te speuren.

We talked about this in the previous thread. I think it’s better to open a new thread for this topic. The method I am going to suggest was once used in my old image processing. So it should work to certain degree.

The idea is to identify overlapping regions between two registered frames. Suppose the pixel brightness in one frame is I1(x,y),…[Read more]

I am working on your data and I am testing a new algorithm. But, I clearly see some problems with the data, probably arising due to applying “dynamic distortion correction” already on the single panel integrations.

There are 2  workflows, that will probably give better results. Can you try any of these 2 if you have spare time, or…[Read more]

It can even handle images that are not linear.  (It was produced during the film era.) So it may be doing more than simple multiplicative+additive calculations.

In my own data processing for large t…[Read more]

Thank you for your request.

I will put this on the RFC list, but it will be completely at the bottom for now.

What would be the use case of supporting Xisf for you since you request this?

Maybe I am not up-to-date, but as long as no camera manufacturers or any capture application uses xisf I can’t see a real use-case for supporting…[Read more]

I have found the cause of this regression instability and I have fixed this for both settings (on/off) of “same camera and optics” while using “dynamic distortion correction”.St-avg-7200.0s-NR-x_1.0_LZ3-full-eq-add-sc_BWMV_nor-AA-RL-noMBB-St

The error is fixed, from all available frames left, APP will automatically choose a new reference frame using the frame quality estimate after star analysis.

I have also checked if all goes well if you were to start 5) Normalize after having removed the reference after 4) Register. This is working without problems as well.

Very good blending result for brightness, gradients and detail.

Two areas of overlapping show star distortion.  Whether these can be joined without issues by other settings I m noy sure yet. More testing to do.
