And I'd really want you to participate! You have already contributed
very valid patches and fixes and I look forward for you to work full
time on Hugin for a while.

you have talent and motivation to pick up this project. Don't worry

in the evaluation.

Next step for you would be to add yourself to the wiki:  and to apply in the
GSoC web based tool.



The application is new so I have no clue how it looks from the student
side. I'd be grateful for feedback. I think you need to create
yourself a profile at



and then apply for hugin/panotools, but I don't know how you would
apply. If you do it, please share with us here your experience, it
will help the other students who are less advanced in the process than
you.

good luck

Sounds interesting. Have you already started building and hacking
Hugin?

Don't forget the pre-condition: we'd like to see a patch to the Hugin

both. it depends on your interests and skill.

hugin and related tools?

Indeed, that would be very nice, if the lens parameters (mainly HFOV) 
are approximately known. An additional least square matching after the 
correlation search would lead to even better subpixel accuracy for the 
control points.

While the homest package by Lourakis is a nice piece of work, I think 
that it would be better to stick with the physical model that panotools 
uses, as that also handle lens distortions properly and would allow 
using fisheye and cylindrical cameras, too. This would mean that one 
"just" needs to implement the right transformation functions, and reuse 
the exiting optimisation algorithms.
The only problem is that all current panotools transformations have not 
been build with moving viewpoints in mind, so the panotools projections 
code would probably need some reorganisation/rewrite to allow this cleanly.

Having a mode for properly mosaicing planar scenes would be an extremly 
welcome addition to hugin.

While I won't be able to be a full time mentor this year, I'd be more 
than happy to answer your questions about the algorithm in [1]. Don't 
let the formulas scare you. From a quick look it seems to work quite 
similar to the khan deghosting (whose paper also sounds more complicated 
than it really is), but contains additional steps to further improve the 
results.

Actually, both algorithms produce a weight values for each pixel in each 
exposure. This weight value could be combined with the weight enfuse 
computes for each pixel.

I don't think doing both is possible in a summer, especially when time 
for learning how the algorithms really work is also needed.

I get a slightly different error:

  The program 'PTBatcherGUI' received an X Window System error.
  This probably reflects a bug in the program.
  The error was 'BadAtom (invalid Atom parameter)'.
(Details: serial 243 error_code 5 request_code 20 minor_code 0)

The ~/.PTBatcherGUI-bruno file gets updated with the new process-id

This version (ver5) crashes here. It says deleted state lock
/path/to/the/lockfile and immediately crashes:

The program 'PTBatcherGUI' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadRequest (invalid request code or no such operation)'.
  (Details: serial 5748 error_code 1 request_code 134 minor_code 6)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the --sync command line
   option to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)


After running with --sync option I got:

PTBatcherGUI: xcb_io.c:242: process_responses: Assertion `(((long)
(dpy->last_request_read) - (long) (dpy->request)) <= 0)' failed.

[hugin-ptx] how to make a horizontal landscape of row of focused book titles with 15cm sequential images

[Jelle de Jong]

-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1

Hello everybody,

I am trying to use Hugin 0.7.0 on debian sid to make a combined image out
of set of other images. I have been trying and reading the hole day and I
can't get the output result that I need.

I have uploaded the first four images and the hugin project file here:
http://filebin.ca/ujjrgg/project1.tar.gz

I have setup some books as test. In a 2,5 meter row. I have set my camera
on macro mode with fixed:
shutter speed : 1/50s
aperture  : f/3,5
iso   : 100
focal length  : 5.00

I had a 500W halogen lamp and a trypot for the camera I moved them both
15 cm to the right and took a new image until all books where captured. I
can sent you all images and can do the imaging over with other settings.

I think the difficulty is that I need an strait horizontal output and
that all titles of the books need to be in focus and exposure should be
balanced correctly. This can mean that some parts of other images should
not be used because an sharper version is available in the other image.

Can somebody please help me? How can we get the correct output? I kind of
lost on this moment...

Thanks in advance,

Best regards,

Jelle de Jong
