[hugin-ptx] Re: Enfuse artifact -- Fairy ring
Thanks everyone for all your comments. Yes, I believe you are all correct about this having to do with the vignetting parameters. I haven't gone back and tried setting them to zero, but I did try something that would have initially tipped me off to the badness about to happen: I hit the Preview Panorama button. Duh. I guess when I was first playing with this the other day, I figured previewing the panorama wouldn't do me any good, since it was an enfuse stack, not actually a panorama. But looking at the Preview window, the phantom ring was clearly visible as a result of the geometry calculations. Obviously it has nothing to do with enfuse, since enfuse has not even run at that point. Erik, I tried your suggestion of running enfuse directly instead of trying to run it through hugin, and the results are very fine indeed!

If you are on windows you can use one of the enfuse droplets in the bin folder. You can even use the enfuse_align droplet to have the images aligned if they should be slightly mismatched. I don't know about other OS but in any case you can use enfuse from the command line:http://wiki.panotools.org/Enfuseorhttp://enblend.sourceforge.net/enfuse.htm best regards -- Erik Krause Offenburger Str. 33 79108 Freiburg --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups hugin and other free panoramic software group.

Yes, the hugin radial lens distortion and vignetting optimisation simply doesn't work when you have a single stack of images - You need to have partially overlapping photos to be able to detect radial variations. Hugin needs to be fixed to workaround this, but for now you need to either reset all lens distortion and vignetting parameters to zero, or load preset values saved in a lens .ini file. -- Bruno --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups hugin and other free panoramic software group.

[hugin-ptx] Re: Enfuse artifact -- Fairy ring
I've spotted the same behavior with Enblend, while stitching a normal panorama from two images with a slightly different exposure and white balance (auto settings from digital point-and-shoot camera). It happens seldom, and after some tweaking of parameters (can't remember which) the effect was gone, at least visibly. I guess just like Tennevin that it has to do with an overly active vignetting correction, so playing around with that might do the trick. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups hugin and other free panoramic software group.
