[hugin-ptx] New primary seam generator in Enblend
Hello all, I'm happy to announce a new primary seam generator that was recently integrated into the Enblend mainline. It was developed as part of the Google Summer of Code 2011 program. The algorithm is based on the idea of Graph-Cuts : http://en.wikipedia.org/wiki/Graph_cuts_in_computer_vision The implementation does not utilize max-flow algorithms, which are relatively slow and memory-heavy. The new seam generator takes into account feature frequency as well as image dissimilarity, and therefore is less likely to cross elements which would make the seam line more apparent, such as beams, fences, railings etc.. This should produce better results than the old seam generator in many cases. The Graph Cut seam generator works best with a fine mask (--fine-mask command line option). It requires more memory and time than the old Nearest Feature Transform algorithm, so it is best to use NFT where efficiency is essential. Graph-cut on the other hand should produce an overall better seam in most cases. For more information on usage and current limitations please refer to the Enblend manual. Special thanks to Thomas Modes and Christoph Spiel for great help and guidance. Also a big thank you for everyone who sent me photos for testing.

[hugin-ptx] Calibrate lens GUI
I've played around with it and this is a really nice application, thanks guys! Can I use it also when focal length/fov is not quite known, or must I get that in some other way? (Hugin for example) The thing is ´my camera has a focal length of 5.1mm eqv to 24 mm on 35mm film, alright. But then I add a housing an a wet-lens and dive with it. The lens have a stated angle of view of 85° (106.5° on land) and magnification of 0.65x. Should I just try to calculate a focal length like this which would suggest something slightly wider than 24mm eqv?

Re: [hugin-ptx] Calibrate lens GUI
Hi yes I have thanks. My question really is, how important is an accurate focal lengt/hfov for a useful result from the calibrate lens GUI? If I approximate the focal length to about 24 when it's probably around 23 something, does it matter for the lens distorsion figures, and does the slightly off focal lengt matter for a panorama or mosaic project? /O 2011/9/1 Carlos Eduardo G.

Re: [hugin-ptx] Calibrate lens GUI
Well, I don't know exactly. I would say you can use approximate values and it wont be a problem. Just try to use spread control points and think about optimizing fov. If you optimize V then the lens will change anyway, so I think the accuracy of the initial value is not so important. Hope it helps. I don't do mosaics very much. I usually do fullsphere panos.

The problem is that nona (the tool that does the remapping) doesn't like your TIFF photos. You need to do some tests with just two photos from the set rather than with all 230 files.

Barrel distortion is purely a function of distance from the centre of the photo - At least this is true for rectilinear images - i.e. you can straighten straight lines and will get the same a,b,c values whatever value you enter for field of view. The Calibrate Lens GUI did originally have an option to optimise field of view, but Thomas removed this on my suggestion for the above reason. ..but with fisheye photos it isn't so clear that the situation is the same, you definitely do need to feed the right focal length into the Calibrate Lens tool. What I don't know is whether it should be possible to optimise field of view at the same time as barrel distortion (with fisheye images). If I approximate the focal length to about 24 when it's probably around 23 something, does it matter for the lens distorsion figures, and does the slightly off focal lengt matter for a panorama or mosaic project? -- Bruno -- You received this message because you are subscribed to the Google Groups Hugin and other free panoramic software group.
