[hugin-ptx] link images parameter with simple function
First of all thanks a lot to everyone who answered me in my latest questions. However I'm here again with another :) I just learned that i can edit .pto files and do things that the Hugin GUI itself doesn't allow, like link arbitrary parameters of images (e.g. yaw of image #10 has to be equal to that of image #0) Now i would like to express that in a more flexible form, like yaw of image #1 has to be equal to that of image #0 plus 36° something like y=0+36 This way i could - for instance - optimize relative positions of three rows in a situation where all images align perfectly with those of their own row, but not with rest of image. Provided i already tried the aforementioned notation 'y=0+36' and that it unsurprisingly doesn't work, is there a way to do what i want? On a slightly related note, although still nice to have, this would not be needed if there was a way to specify a coarse expected position, as i already pointed out: i guess the optimizer works by minimizing some sort of error function, and should be trivial to add [distance from image being optimized to the originally setted expected coarse position] to the error function to minimize; is such a feature present or planned? I couldn't figure exactly when i first asked for it. In case of two negative answers: would it be difficult to add for a professional developer, given proper advice? -- You received this message because you are subscribed to the Google Groups Hugin and other free panoramic software group.

[hugin-ptx] Re: multiblend 0.3beta - now with pseudowrapping for 360 degree panoramas
Hi David, I think I may have seen it, and meant to reply one day, but then I forgot... No problem :) Anyway, I will look into adding your MCE support for the next version - thanks for those. Since the project has been renamed to MXE instead of MCE we'd probably better call it by its proper name MXE from now on. Just curious, why is -lz necessary in the build script? Both libjpeg and libtiff make use of zlib functions. Normally you'd expect the compiler to add this -lz automatically when the build system was properly configured and you include -ljpeg of -ltiff. Unfortunately at least on my system this seems not to be the case, resulting in lots of errors like undefined reference to _inflate. Adding -lz manually resolves this (and adding it twice won't hurt the compiler). This may have to do with an incomplete pkg-config file in libtiff or libjpeg which may or may not have been fixed (note that my MXE system isn't entirely up-to-date, I'll check this later). I will add seam saving/loading soon as well, but I will use TGA as it is easily compressed (although PNG may be even better). TGA may be nice compression wise, but I don't think this format is as widely known as TIFF or PNG, so I'd opt for using the latter. Note that this is pretty straightforward when using (for example) the freeimage library (as opposed to using functions from libtiff or libjpeg directly). Cheers, Bart There may also be some disk caching features added, although the biggest problem at the moment is heap fragmentation (and this may actually be the cause of Evgeny's problems, rather than running out of memory).

Re: [hugin-ptx] merge enblend and multiblend code?
Yah, probably would be, especially for complex image sets. Maybe could make it a manual option user could specify on starting a stitch; maybe even select which image to start with for each thread. Then if it blows up, user can try it again without it. But, yah, be just faster to run seaming in a single thread!

For example, a strip panorama - do the seaming for the first 2 images while also doing the seaming for the last 2 images (assuming there's enough images in the pano for that to work). Maybe use opposite corners for multi-row/multi-column panos.

Note that this is pretty straightforward when using (for example) the freeimage library (as opposed to using functions from libtiff or libjpeg directly). It's all coded up now - I've gone for PNG as TGA can only give you up to 1/256 compression, and as you say it is more widely known. -lpng will be a requirement for the next version (just waiting on some test files for a TIFF variant).

And if you're python- literate, you may also want to have a look at http://bazaar.launchpad.net/~kfj/+junk/script/view/head:/main/README.parse_pto http://bazaar.launchpad.net/~kfj/+junk/script/view/head:/main/parse_pto.py This is pure python and will run on any system with python 2.6 or 2.7 and may run on 3.X. and if you're on a linux system, you may be able to use hsi/hpi as well from python (it might be part of your package already), which is a swig module for most of hugin's backend functionality. It's complex but fast and largely undocumented, for your purpose it's probably overkill. What the optimizer minimizes is the distance of the 'legs' of the control points, when projected to the output projection. This sounds confusing, but you have to keep in mind that each control point refers to two coordinate pairs: one x/y pair in each image. Hugin has a notion of where these two points would turn up on the output under the current transformation, and since the match is never perfect, the projected positions of the two 'legs' aren't in precisely the same spot - hence they are in a certain distance from each other. The optimizer tries to modify the projection so that the distance between the projected legs is minimized. It doesn't look at the image content at all, it only works on the control point coordinates and their projected positions.

[hugin-ptx] viewer that uses image pyramid
