Marco,

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

HUGIN GUI Discussion / Re: Information Entropy Minmization Discretization
« Last post by Anders L Madsen on September 04, 2021, 16:21:57  »
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
Anders

HUGIN GUI Discussion / Information Entropy Minmization Discretization
« Last post by MarcoGV on August 30, 2021, 20:18:13  »
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
« Last post by Late_Junction on June 28, 2021, 11:20:16  »
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).

HUGIN GUI Discussion / Re: Plate Models

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: https://www.youtube.com/watch?v=Go7O6-UfFWk

Hope this is useful
Best regards

HUGIN GUI Discussion / Plate Models
« Last post by MarcoGV on March 22, 2021, 21:55:17  »
Greetings to all.  Is there a way to specify plate models directly in Hugin?  Or, maybe even just repetitive models such as the one in Figure 3.46 in Jensen and Nielsen's 2007 book, _Bayesian Networks and Decision Graphs_, 2nd ed.?

HUGIN GUI Discussion / A More General Zoom Feature
« Last post by MarcoGV on March 10, 2021, 21:56:47  »
The Zoom feature of the Hugin is very useful.  Unfortunately, it only affects the size of networks in the network pane.  It would be very useful to have a way to increase the size of all parts of the GUI.  For example: I have to take off my glasses and get very close to the screen to read the names of variables, variable values, and probability values in CPTs.  I have to do the same with the belief bars in run mode.  Is there any fix for this?  If not, is there are any plan to add a more general resize feature?

HUGIN GUI Discussion / Hugin Dark theme (for Windows)
« Last post by bobbsterman on December 31, 2020, 19:12:39  »
Hi all!

I love Hugin and hoping I could find a dark theme for it (on Windows). I made a poor very hackish version by simply editing some of the XRC and resource files (see attached - feel free to use and share). The results are... not the greatest xD

Does anyone know a better way to do this?

Cheers

Hello,

I'm not sure to be on the right forum - I see it seems not very active -, but I try to explain my issue. Sorry also for my English which is far to be perfect.

I'm looking to take photos at the same place and approximative same focal length than done for old photos taken in my town (postal cards). As you may know, a distorsion problem appears. I wonder whether Hugin would be able to correct these distorsions in order to get very similar photos, time/date excepted. The method would consist in having the old and new photos in a window and to select couples of dots on each photos... as we do with Hugin to assemble photos in a panoramic view... and then, execute the computation in order to apply a distorsion correction on one of the photos.

Does this feature exist ? If not, I think it wouldn't be a great challenge to add it ? Do you agree ?

Best regards,
Piblo (a French amateur photograph)

RHUGIN / Problem running RHugin using latest version of HUGIN
« Last post by Anders L Madsen on April 20, 2020, 10:40:31  »
The RHugin plugin (https://github.com/huginexpert/RHugin) searches for the HUGIN installation is a specific location. This location is no longer used to install HUGIN software.

Here is how to solve the issue on the Windows platform:

RHugin tries to locate the Hugin installation, but fails because the naming of the Hugin directory has changed.  Try the following workaround:
  • Start a “Command Prompt” with “Run as Administartor” privileges.
  • CD to the directory that contains the Hugin installation ("C:\Program Files\Hugin Expert").
  • Run this command: mklink /D "Hugin Researcher 8.8 (x64)" "HUGIN 8.8 (x64)"
     

Notice the Hugin/HUGIN distinction in the mklink-command.

Then follow the instructions for installing the RHugin package.
