If the images all constitute one stack, do as I proposed.

Hugin's process is by no means unique - there are many other programs doing pretty much the same thing. The difference is that hugin is FOSS and quite rich in features, so you can even bend it to uses like your denoising by stacking. I have a hunch that for your particular purpose you may fare better if you increase enfuse's exposure sigma, since your not aiming at well- exposedness but simply want to average the shots to remove noise. The default value is .25 (I think), so if you enter --exposure-sigma=X with X (probably much) higher than .25, you may get the results you want. And set saturation-weight to zero. Really, enfuse is a tool to pick the 'best' bits from several images, but with noisy images, how would it know what is best? Actually this makes me think that it might be a nice option to add to enfuse: something like --fuse-all, which would give equal weight to pixels from all images and just use the fusing mechanism. But a large value for exposure-sigma should do the trick as well. so for your enfuse options, try something like --saturation-weight=0 --exposure-mu=50 > If anyone is interested, I have a background in user experience and > interpretive design and I would love to work with someone in the Hugin > community to produce some material that might be helpful for many > other users like myself, who are having difficulty. > [email protected] The panotools wiki, where the documentation lives, is open for everyone to participate. I'm sure a good overview article would be welcome: http://wiki.panotools.org/ If you'd rather just evolve text offline and have conceptual difficulties, I'm sure this ML will happily help you get it right. I suspect, though, that before you can create useful documentation, you'll have to go through the process of learning the concepts and tools involved - it's a complex field, as Bruno has pointed out. Yet again, if you have difficulties and questions, that's what the ML is for.
