Installed Hugin 2015 from Debian Testing, reports error loading shared library

When I try to start Hugin 2015, nothing happens. Starting it from a 
command line gave me this error:

hugin: error while loading shared libraries: libvigraimpex.so.6: cannot 
open shared object file: No such file or directory

Debian Testing's version is (apparently):
1.10.0+dfsg-11
libvigraimpex5v5

How do I fix this? Thanks.

Pano_modify and Hugin 2014 : unrecognized option

Hi,

I'm refining my script processing, and I want to replace a 'ptoset' call  (from Bruno Postle's Panotools scripts ) by a 'pano_modify' one; my goal is to set JPG type and compression after pto creation.

I've seen  that pano-modify manpage (http://wiki.panotools.org/Pano_modify ) offer --ldr-file and --ldr-compression options since 31 May 2014. But it doesn't seem to be present in hugin 2014 :


pano_modify: unrecognized option '--outpu-type=N'
pano_modify: unrecognized option '--ldr-file=JPG'
pano_modify: unrecognized option '--ldr-compression=92'

Is that normal or have I done a mistake ? How can I make it with another tool?

Fabkzo

Mildly off topic - rephotography?

There was a lot of noise a while back (good $DEITY, it was 2010)
about some software at MIT that helped get the camera
into the right place;

http://www.geek.com/news/new-camera-software-allows-you-to-line-up-your-photos-with-the-past-1272643/

(full paper: http://people.csail.mit.edu/soonmin/rephoto/rephoto.pdf)

But I can't find any information that falls *BETWEEN* the 2
extremes of "keep moving tilll you get it right" and the MIT software.

Does anyone know of any other guides to technique and/or software aids?

I'm guessing lining up old and new photos might be mildly relevant to Hugin.

Enfuse bug? saturation-weight inverted

The Enfuse option --saturation-weight seems inverted. Adding --saturation-weight=0 always yields an image that has stronger colors than if I leave the option out.

I usually begin running my images through Enfuse with no options. I then try --saturation-weight=0 and compare each image pair. I usually end up keeping this one since I like vivid colors. (Enfuse always is on the bleak side unfortunately).

I noticed this several years ago but forgot to post until now. It seems like a minor bug. But I'm surprised no one else has mentioned it so maybe I'm misinterpreting the meaning of the option. (I'm not sure about the other weight options, whether they are also inverted).

Strange behaviour with 2016.0.0.5cc09f0259b5

I'm trying to create a panorama using 2 pictures with the 2016.0.0.5cc09f0259b5 version on Lubuntu 14.04.

I load the pictures, search for control points and they seem ok in terms of distance between control points but the preview is really strange... i don't know how to proceed.

The pictures are made with a 10mm with an aps c (1.5x) camera.

Here they are (downscaled, the result is the same with high res pictures) together with a screenshot of the preview:

https://goo.gl/P9mQ2z

Btw is there a way to Move/Drag the image with the keyboard? I often use shift+mouse left right and it works quite well but i find difficult to micro-adjust it vertically (shift+mouse up-down), it's more "contrained" and the slightest adjustment i can do is sometimes too big.

Thank you in advance.

enblend failure ...

First time that I run into this particular issue : enblend color transformation fails (which I think is the maijn issue), followed by a file access error, which is probably a side effect.

Main difference : 16bit gray scale images instead of 24bit RGB

Questions about PTGui

Hello All,
I recently helped a PTGui user who was having trouble getting a good  
stitch from his project images.
I stitched the project using Hugin-2016.0.0 beta1, and could only describe  
to him how I went about it.
It would be much clearer to him if he could load my project file.
Does anyone know if PTGui can read and make sense of Hugin's .pto files?

Cheers,
-- 
Regards,
Terry Duell

Compilation fails in debug mode

I have tried to compile Hugin in debug mode (-DCMAKE_BUILD_TYPE=Debug)
and found a few issues. The patches are attached. Hugin_shared.h.patch
is just cosmetic change in order to MinGW's gcc doesn't complain about
#pragma warning.

Regards,

Hardware to improve performance of Hugin

hello,

Probably this question was already asked, but a lot changed in Hugin (we can use OpenMP or GPU (i suppose not both at the same time)) so I ask again.

I currently considering changing my PC on which I use Hugin. I wondering what is best hardware for Hugin ?

I was thinking about some configurations on CPU (in configurations below I am not counting HT feature of CPU):
1. Hi core CPU (ex. 8-10 cores), but lower frequencies like Xeon family (and mainly use OpenMP version)
2. Low core CPU (2-4 cores) but higher frequencies like i7 family
3. Low core CPU (2-4 cores), with some multi GPU configuration ?

Can hugin works with MultiCPU + MultiGPU configuration at the same time ?

[patch] fixup whatis in pto_var manpage


Hello,

the formatting of the pto_var manpage was broken (again ;-) in 2016.0 with
