[hugin-ptx] New primary seam generator in Enblend

2011-09-01 Thread Rosomack
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

[hugin-ptx] Calibrate lens GUI

2011-09-01 Thread Oskar Sander
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

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

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

[hugin-ptx] large pano problem

Large pano, (3 something gigapixels, 230 images. I started this in Autopano, moved the project to hugin, where it loaded fine (except first image that needed some tweaking). I then went through opimization steps, Exposure and stitch. The created stitch starts out seemingly ok - then starts to
