# 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, panomatic or autopano for automatic creation of control points.
- nona for remapping input images and rendering output images.
- enblend and enfuse 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 correct exposure, Vignetting and White balance between photos; generate HDR or exposure blended output from bracketed photos; or use 16bit and HDR input data natively.

## 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 a 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.
- pto2mk generation of Makefiles for command-line stitching.
- cpclean command line tool to remove control points with improbable error distances
- calibrate_lens automatic lens calibration using straight-line detection
- vig_optimize command line tool to estimate photometric parameters.
- hugin_hdrmerge merges multiple exposures to HDR using Khan anti-ghosting algorithm
- hugin_stitch_project a GUI tool to stitch a single hugin .pto project.
- celeste_standalone removes cloud-like control points from project files.
- PTBatcherGUI a GUI queue manager for stitching multiple hugin projects.
- PTBatcher command-line access to the hugin Batch Processor stitching queue.
- panoglview OpenGL panorama viewer stored in sourceforge SVN alongside hugin which must be built separately.
- autopano-sift-C version of autopano-sift written in C, also needs to be built separately.

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.
