Hugin (software)

Hugin and the associated tools can be used to

• combine overlapping images for panoramic photography
• correct complete panorama images, e.g. those that are "wavy" due to a badly levelled panoramic camera
• stitch large mosaics of images and photos, e.g. of long walls or large microscopy samples
• find control points and optimize parameters with the help of software assistants/wizards
• output several projection types, such as equirectangular (used by many full spherical viewers), mercator, cylindrical, stereographic, and sinusoidal
• perform advanced photometric corrections{{cite web|url=http://hugin.sourceforge.net/tech/|title=Hugin Research Corner}} and HDR stitching

With the release of 2010.4.0, which includes a built-in control point generator, the developers consider Hugin to be feature-complete.{{cite web|title=Hugin-2010.4.0 release notes|url=http://hugin.sourceforge.net/releases/2010.4.0/en.shtml|publisher=SourceForge.net|access-date=19 January 2011}}

The Hugin development is tracked on Launchpad{{cite web|url=https://launchpad.net/hugin|title=Hugin in Launchpad|date=30 September 2005 }} and the code resides in a Mercurial repository.{{cite web|url=http://hugin.hg.sourceforge.net/hgweb/hugin/|title=SourceForge: Mercurial repositories index|access-date=2011-01-01|archive-url=https://web.archive.org/web/20121010200207/http://hugin.hg.sourceforge.net/hgweb/hugin/|archive-date=2012-10-10|url-status=dead}}

Five projects for the development of Hugin / panotools were accepted for the 2007 Google Summer of Code. Additionally a sixth, community sponsored project has been set up. The projects were:

• Automatic feature detection by Pedro Alonso (Spain), mentored by Herbert Bay (Switzerland)
• New modular GUI by Ippei Ukai (Japan), mentored by Yuval Levy (Canada), who is also the lead administrator on the Summer of Code effort
• HDR de-ghosting by Jing Jin (USA), mentored by Pablo d'Angelo (Germany) who is also the lead developer on Hugin
• Large image processing with VIPS by Mohammad Shahiduzzaman (Bangladesh), mentored by John Cupitt (United Kingdom)
• Interactive Panorama Viewer by Leon Moctezuma (Mexico), mentored by Aldo Hoeben (The Netherlands)
• Community project: PTbatcher by Zoran Mesec (Slovenija), mentored by Daniel M. German (Canada)
