Hugin-0.7.0 release notes
Hugin is a panorama stitcher and more.
Changes since 0.6.1
Hugin has changed enormously in the two years since the 0.6.1
release, hardly any part of the code has remained untouched. There
have been many many bug-fixes, improvements to the interface and
lots of new features - Here are just some of them:
Hugin now has comprehensive help documentation for the entire user
interface, the manual now includes glossary items explaining many
panorama stitching and related photography concepts.
New translations include Slovak, Korean, Bulgarian and Spanish. This
means that hugin is now usable with a total of twenty languages.
New Assistant panel
Creating simple panoramas is much easier, hugin now starts showing
an Assistant with a simple 1-2-3 approach for loading images,
aligning and creating the final output.
The Assistant will estimate lens and camera parameters, then pick a
suitable output projection and size, advanced options are still
available for manual adjustment.
Previous versions of hugin and panotools had basic support for
correcting vignetting and exposure differences between photos.
This has been completely overhauled, hugin now internally uses the
EMoR model for representing exposure photometrically. This means
that the camera response curve, vignetting, colour balance and
exposure can now be optimised in much the same way as geometrical
properties such as position and lens distortion.
The result is that blending between photos is better than ever
Previously hugin supported High Dynamic Range imaging solely by
allowing stitching of HDR floating-point TIFF photos - These images
themselves had to be created in another tool.
Now, thanks to the internal photometric model, hugin can now create
HDR output from normal exposure bracketed photos. The photos don't
have to be perfectly-aligned, they don't even need to be
nearly-aligned or have consistent exposure differences - The hugin
optimiser will sort all this stuff out, and the stitcher will create
OpenEXR or TIFF HDR output files for later tonemapping or use as
HDR and tonemapping isn't for everybody, enfuse introduced exposure
blending to the world, and hugin supports aligning and fusing
bracketed stacks of photos, perfectly, all as part of the stitching
So now with hugin-0.7.0 and enblend-3.2 you can create realistic,
photographic panoramas that have no over-exposed or under-exposed
hugin-0.7.0 introduces a new stitching back-end: previously the
various stitching tools were executed directly by the GUI, now all
the commands required to generate the output are written to a
Makefile which is then processed independently of hugin itself.
Aside from easier debugging and customisation; this background
stitching allows you to get on with creating a new project while
waiting for the previous job to finish - Stitching can also be
deferred or shifted to another machine, even 'headless' servers can
now be used.
Hugin has always had the ability to save panoramas using simulated
normal and fisheye lenses, or 360 degree cylindrical and spherical
Now a whole series of alternative cartographic mappings are
available, of particular interest are the 'conformal' stereographic
and Mercator projections which can be used to show extremely large
angles of view with no local distortion.
Hugin project files can now be used as templates for new panorama
projects. This is useful if you take a lot of panoramas with exactly
the same camera positions.
There's a whole lot of other new stuff in this release: numbering in
the control-point editor, straight-line control-points, numeric
transform, clicking to rotate the preview, a straighten button,
cropping of the output and probably more.
This release provides new command-line tools:
* align_image_stack: align a nearly-aligned stack of photos
* pto2mk: create a stitching Makefile from a pto project
* vig_optimise: optimise photometric parameters
* tca_correct: calculate lens chromatic aberration
* hugin_hdrmerge: assemble a bracketed stack to HDR
* matchpoint: classify control point features
Control point generators
Hugin doesn't yet ship with a 'Patent Free' control point generator.
So you either need to pick control points manually - Not as
difficult as it sounds - or install and configure one of the
following control-point generators as 'plug-ins', in no particular
* Autopano freeware version
Upgrading from previous versions of hugin should be seamless. If you
do have problems with old settings, these can be reset in the
Preferences by clicking 'Load defaults'.
See the the README and INSTALL_cmake files for more information.
Thanks to all the contributors to this release and members of the
ptx mailing list, too many to mention here.

I didn't know so many (other) people didn't know about it.
The performance of Hugin/Enfuse greatly exceeds their
