# Hugin

Hugin is an opensource graphical user interface (GUI) for Panorama tools.

Like other GUI front-ends, hugin provides an easy-to-use unified point-and-click interface to a whole range of other command-line tools including:

- autopano-sift, autopano-sift-C or autopano for automatic creation of control points.
- nona or PTmender for remapping input images and rendering output images.
- enblend for seamless blending of output images.

The Hugin project's mission is not only to provide a powerful GUI, but also to provide opensource replacements for the small number of closed source components of Panorama tools, especially PTStitcher. A PTStitcher replacement, called nona has been developed, supporting its most important features.

Among the many flexible Hugin workflow options, it is possible to use increased tonal range data in a 16bit workflow with hugin or work entirely with high dynamic range images such as floating-point TIFF from start to finish in a HDR workflow with hugin.

## Hugin components

The following tools are part of the hugin suite:

- hugin the gui front end.
- nona a command-line replacement for PTStitcher.
- fulla correction of barrel distortion, chromatic aberration and vignetting.
- nona_gui a version of nona with simple gui progress dialogs, similar to the windows version of PTStitcher.
- autooptimiser an experimental tool with the same interface as PTOptimizer except using pairwise optimization which doesn't require any manual pre-placement.
- align_image_stack a tool to automate the process to align a stack of photos.
- tca_correct a tool to automatically generate chromatic aberration correction parameters for use with fulla.
- matchpoint feature identification.
- vig_optimize command line tool to estimate photometric parameters.
- panoglview OpenGL panorama viewer stored in sourceforge CVS alongside hugin which must be built separately.
- hugin_hdrmerge merges multiple exposures to HDR using Khan anti-ghosting algorithm
- hugin_stitch_project batch stitches a hugin project, performing any HDR merging or blending as necessary.

More information, documentation and tutorials are available on the project website.

## Development

Hugin is Open Source, and like every community-developed software very much dependent on voluntary contributions of resources. If you have coding skills, you are welcome to look at the source code and contribute to it. Even if you don't have coding skills, you most likely have some skills that the project could use and you are more than welcome to contribute your time. The tasks requiring attention change frequently and so do the required skillset and resources. Find more about the development process.
