Response File Crashes enfuse

I've been using enfuse 4.0  When I try to use the version that comes with Hugin 2014(4.1.2) it crashes with the cmmd line:
enfuse  --output=myoutput.tif  <at> efList

enfuse(1743,0x7fff78082310) malloc: *** error for object 0x7fff78c24330: pointer being freed was not allocated
*** set a breakpoint in malloc_error_break to debug
Abort trap: 6

Using individual  file names for the input files works fine.    Here's what the help file says:
Usage: enfuse [options] [--output=IMAGE] INPUT...
Fuse INPUT images into a single IMAGE.
INPUT... are image filenames or response filenames.  Response
filenames start with an " <at> " character.

It appears this was taken out for some reason.  Am I missing something?

Minor triumph

I had a very detailed, VERY old map of part of a town.
I had a large, quite old map of a larger part of the town.
Google Earth gave me an image of the current (totally redevelopted)
area of the first map.

The two old maps were rotated w.r.t. to North, and all 3 image were
at different scales.

I was able to use Hugin to tie both the old detailed map, and the
current google earth map to the large intermediate
map, and thus use google to get an accurate lat/long
fix for all the location of interest on the old, detailed map.

Hugin's transform optimisation was particularly valuable, since
it transpired that some of the most distinctive building and
landmarks on the older maps had been drawn larger
than they should accuretely be, for emphasis.

Notably, the version of the Church on the map nearly filled
the churchyard, which is not the case in reality.

Setting lots of CPs and optimisation revealed (and eliminated
the error from) these quirks.

Thank you, Hugin!!

Hugin produces unuseable .hdr files

I am trying to work with HDR images produced by Hugin.
Hugin seems to combine the images fine, but no matter if I use TIF or EXR output, no program can open the hdr images.

For the .exr files it is obvious they are not valid images as the file size is way too small, like 40 KB for a hires image.
The tiff file sizes seem OK but the .TIF files can't be used either.
Artizen HDR or HDR Workshop for example can't open them.

Are others having the same problem?

DOF Depth of Field stack

I am trying to stack a bunch of macro photos in order to increase the DOF. Hugin stack does well for exposure stack but
the pictures get fuzzier not clearer.

Is there a setting that I am missing?

How to reproject equirectangular image correctly?

I want to reproject some aerial equirectangular images taken with a Ricoh Theta camera. I want to rotate the images to a particular orientation, then write the image back out as a new equirectangular image of the same size, but with a different orientation.

Here is what I have tried:
* run Hugin.
* Select "Add images..." and load my (already perfectly stitched) equirectangular image.
* Select "Equirectangular" as the Lens type.
* Select "Fast Preview Panorama".
* Select the "Move/Drag" tab in the panorama viewer window.
* Drag the image around until a) the horizon is perfectly level, and b) my desired reference point is horizontally centered in the image.
* Select the "Stitcher" tab in the stitcher window.
* Select Equirectangular projection
* Select 3584x1792 (the original image size) as the canvas size
* Select "Remapped Images"->"No exposure correction, low dynamic range"
* Click "Stitch"

But the resulting image has a dramatic exposure discontinuity seam, at the location where the original image left/right edges were, i.e. at the seam between the original horizontal +180/-180 degree boundary. What should I try next, to avoid this seam?

Is there another program I should use to perform this sort of reprojection from equirectangular to equirectangular?

SHA1
02b16788b65e40a4f71b56b84eef376069c4c9e5  hugin-2015.0.0_rc1.tar.bz2

Changes since beta2
* Some translations have been updated. But there are still missing updates to some translations files.
* Updates to man pages.
* Updated copyright header
* Updated some CMake scripts for building on Windows
* Bug fix: Don't crop output when using internal blender
* Bug fix: Use correct encoding for progress display [1459364]
* Bug fix for adding several images without EXIF data at once
* Fixes leveling of panorama from command line
* Prevent crash when deleting control point from cp list
* Changed internal order for crop factor calculation
* Improved range checking for interpolating when reading from lens database

Rc1 is identical to changeset d497c7fc18666 in our repository, which is also tagged as 2015.0rc1

The release notes are here http://hugin.sourceforge.net/releases/2015.0.0/en.shtml
They are already translated to French and German:
http://hugin.sourceforge.net/releases/2015.0.0/fr.shtml
http://hugin.sourceforge.net/releases/2015.0.0/de.shtml


EXECUTABLES
Users communities produce executables for their respective platforms. They will be announced in this thread.

CHANGES SINCE 2014.0.0
* Hugin 2015.0 has a number of new features. Most of the changes are under the hood to improve stability, allow easier maintenance and easier addition of new features.
* The makefile based stitching engine has been replaced with direct calls to the underlying programs. This should reduce the overhead of calling the same program too often and so speed up the whole process. Hopefully this also allows the usage of more unusual characters in the filename. Instead of pto2mk and make we now have hugin_executor which can also be used for running the assistant from the command line.
* Hugin now has it's own blender, verdandi, based on a watershed algorithm, which has been included in 'nona'.  verdandi can be chosen as the blender by choosing "builtin" in the stitcher tab, and can also be set in  the Preferences. verdandi can also be called as a command line tool.
* The lensfun library has been removed as it did not fulfill our expectations. It has been replaced with our own camera and lens database which uses a data mining approach and operates automatically without user intervention. Geometric distortion and vignetting data have to be loaded manually.
* The fast preview window has a new tool to add or remove control points to selected areas in the output projection.
* Automatic exposure stack detection is now applied when loading images, and an option has been added to unlink image position when adding stacks.
* The fine-tune and auto-estimate functions in the control point tab have been made projection aware. It should now work also with images with different fov or different projections. The fine-tune feature has had a significant speed up when Hugin is compiled with the libfftw3 library (optional).
* PTBatcherGUI has more choice for the end of the process: depending on the operating system the PTBatcherGUI can be closed, the computer can be shut down or send to the hibernate mode.
* PTBatcherGUI now shows the thumbnails when searching for images in directories.
* Many of the underlying tools in hugin are now able to use available cpu cores.

New tools added:
** verdandi: tool for image blending
** hugin_executor: stitching and run assistant from command line
** hugin_lensdb: tools for lens database maintenance

One thing not fixed in beta2 or is it enblend 4.1.3?

I have it here on 64-bit Linux.

I shoot RAW files, convert them all using the same program with the same 
settings ... and enblend insists that none of the input 16-bit TIFFs 
have the same ICC profile. Yet every single frame DOES have the same ICC 
profile. Which enblend dutifully reports that both images have the same 
ICC profile, while warning me that they don't.

enblend: warning: input image "pict2089-20150607-pict2096-201506070003.tif"
enblend: warning: has ICC profile "sRGB IEC61966-2.1",
enblend: warning: but first image has ICC profile "sRGB IEC61966-2.1";
enblend: warning: blending images with different color spaces
enblend: warning: may have unexpected results

enblend: warning: input image "pict2089-20150607-pict2096-201506070004.tif"
enblend: warning: has ICC profile "sRGB IEC61966-2.1",
enblend: warning: but first image has ICC profile "sRGB IEC61966-2.1";

automatic use of lens

This is a wish, perhaps there are arguments against it?

When I load images into hugin, could one change the configuration in such a way that the lens-parameters, if available in the lensfun database, are
AUTOMATICALLY loaded?

2015 beta2 ram usage

Hello everyone,

 i have just installed 2015 beta2 from ppa ubuntu next on lubuntu 14.04 64 bit and found out a strange problem (and also a crash reported in the 2015 beta2 thread).

This time i choosed control points manually, it needed a lot of manual adjustments but at the end alignment was almost perfect ;) .

Trying to stich a panorama consisting of 2 horizontal images (16 megapixel each one, tiff files developed from raw with rawtherapee) i have found out that ptbachergui uses more than 4gb of ram (all i have in this pc) and it's incredibly slow (in fact i had to kill it since it was swapping a lot), but it took more than 6 minutes without a result.

Also with that tiff files the preview windows shows wrong exif values (68.882 focal length and 0.599 crop factor) while exiftool shows this:

exiftool DSCF3061.tif |grep -i focal
Focal Length                    : 25.6 mm
Focal Length                    : 25.6 mm (35 mm equivalent: 38.0 mm)

I can upload images and pto if needed.

Thank you in advance.

Verdandi: the new blender

Hi,

I did some preliminary tests with verdandi(1), the new blender. In general it works fine, but in 2 panos I got "washed out" colors, maybe due to CIECAM colors in the originals (That comes to mind now that I type this mail. I will check tonight).

It is much faster then enblend, just like multiblend is/was.

Some french website also paid attention to it: http://www.panophoto.org/forums/viewtopic.php?f=67&t=15190

Are there any other users already with test results?

Harry
