General Discussion / A searched feature
« Last post by Piblo on July 08, 2022, 15:28:40  »

Sorry if my post is in a wrong forum dscussion.

I'm looking for a feature that I can't find in Hugin. Either, it doesn't exist and it would be useful for many users, or I don't know how to find it.

I work on photography reconductions. I take pictures of views printed on old postcards... at the same location they were taken more than one century ago. I then mix them in a single photo.

Even with using equivalent focal lengths than for the originals, I must deform the recent picture in order it matches to the old one. As for panoramics with Hugin, I'm able to identify control points that would be used by a similar software. Until now, I manually modify the new picture thanks to GIMP and this is tedious and inaccurate.

What I would need, as output, is only the recent picture modified thanks to a process that use the control points... in order to use it later as a calc in GIMP. I don't wish the software automatically produces a mixed picture itself.

Please, could you help ? Thank you.

General Discussion / Excel, Dates, and Discretization
« Last post by MarcoGV on May 03, 2022, 22:15:24  »
I recently ran into a problem that I do not know how to solve in a simple way.  It turns out that Excel automatically turns an entry like 5 - 10 into a date; in this case, May 10.  (I am in the U.S.)  (See  After discretization of a data set where one of the intervals is 5 - 10, the .cvs file built by Hugin has May 10 entries wherever 5 -10 should be.  Attempts to convert May 10 to 5 - 10 by formatting cells fail, because 5 - 10 is turned into a number representing the number of days from the "beginning of time," and trying to convert that number back to 5 - 10 results in May 10 again.  Does anyone have any suggestions to solve this problem?

The sizing of features in Hugin 9.1 is much better, at least in Windows.  Thank you for this improvement, which makes using Hugin more pleasant.
General Discussion / Re: cross-validation

Are there any updates on the possibility of a cross-validation tool in Hugin?  I would find it very useful to complement the existing classifier performance tool.
Hello Developers,

I am a beginner at Hugin software and trying to learn the software using HUGIN LITE. I wish to work with the raster files and for them, I am trying to build a Bayesian network. My problem is when I select the node type to interval and enter the values for the raster file (e.g. Indices, which has negative and positive values) manually in the table, it does not accept the values. I am not able to find any option where I can link the corresponding tiff file to the node. On youtube, the tutorial to build the model and attach or link the rasters to the node has not been explained but only to enter the values manually in the table of node has been demonstrated.

Please help me in this initial phase so that I can learn the model and further apply it in my research work.

Thanks in advance!

We are working on a new type of monitors that will support better zoom functionality.

Hi Marco,

The IEM discretization method is based on the algorithm of the following paper:

U. M. Fayyad and K. B. Irani. 'Multi-Interval discretization of continuous valued attributes'. In Proceedings of the Thireenth International Joint Conference on Artificial Intelligence, pages 1022-1027, 1993.

If you have ideas for other (or better) discretization algorithms to implement, then please let us know.

Best regards

Greetings!  Could someone please explain in more detail that in the manual what information entropy minimization discretization does? I tried it with a file with 10000 cases generated from the anginaContinuous network in Section 3.3.8 of Jensen and Nielsen's book, discretizing the Therm variable with the Angina variable as target.  It gave reasonable results, with three intervals.  Maybe someone could look at that example and use it to explain which entropy is minimized.
General Discussion / Supported image formats

My Linux install of Hugin 2020 does not find the required image data in the .RAF files from my Fujifilm X-T30, but is satisfied if I export those files from darktable in 8 bit TIF form. I am correct in assuming that Hugin doesn't support raw files - or have i missed something from my installation? (I failed to find any info. on supported image file formats in the Help wiki).

Hi Marco,

You can try to use the combined OOBN and DBN facility in HUGIN. Maybe it is sufficient for your needs? In the DBN you can define the number of time steps in the time window.

We have a YouTube tutorial on DBNs in HUGIN:

Hope this is useful
Best regards
