Hugin (Software)

Hugin is a free stitching software, which is mainly developed by Pablo d' Angelo. It is a GUI for the panoramic tools (also known as PanoTools ) and other tools.

Thanks to intelligent equalizing algorithms not only linear panoramic images side by side in rows of photos are possible, but also the creation of high-resolution photos, the photos can also be positioned above each other. Hugin can automatically detect from Exif data of digital cameras, the focal lengths of shots, but it is also possible to specify this by hand. It is also possible to create profiles for their own lenses. Since version 0.6 it is possible to correct for vignetting in the output images, with version 0.7 Hugin can determine the correction parameters for themselves, version 0.8.0 also comes with a new preview window many other changes. There is also the possibility to display the same output images completely different with different projection methods.

In order to optimize their relative position to each other ( and other parameters) prior to assembly of frames needed Hugin Control Points, the identical points on two or more select overlapping frames. Normally these control points must be set by the user, the programs Autopano - sift or Autopano, for both must be the mono environment and installed for Autopano - sift under Windows. NET on Mac OS X and Linux be such points can, however, also automatically Mark. In October 2009, autopano - sift -C 2.5.1 released on the Hugin website, including installing Mono or. NET is not necessary since it is written in pure C. Autopano - sift and autopano - sift -C using the SIFT algorithm for finding control points. Since version 2010.4.0 Hugin has cpfind with its own control point generator, which is not based on the patent -prone SIFT algorithm.

When blending of frames may result in unsightly abrupt brightness transitions that can be triggered, for example, by different exposure or aperture settings. Similarly, double vision possible when the recordings were made not just to the often referred to as nodal or junction point of the camera around, where no parallax errors occur, or moving objects are located in the images. To avoid these problems, or at least mitigate, (also version 4.0 now ), Enfuse or Smart Blend can be used to blend the programs Enblend.

Furthermore, it is possible that the wizard for creating the parameters are used. New in this version include the automatic exposure and Vignettierungskorrekturen.

Some of the changes in recent years emerged as part of the Google Summer of Code program in 2007, 2008 and 2009.

The same output images as fish-eye projection and viewing angles on the ceiling.

The name " hugin " was proposed by Nils Lagerkvist.

Trivia

Hugin was one of Odin's two ravens ( Hugin and Munin ) and translates approximately as much as "thought" or " mind." There is also a software called Munin.
