hugin

hugin can be used to stitch multiple images together. The resulting image can

span 360 degrees. Another common use is the creation of very high resolution

pictures by combining multiple images. It uses the Panorama Tools as back-end

to create high quality images

Command-line tools are available to generate panoramic images and to batch-process

hugin projects.

Examples of what you can do with hugin:

Stitch and blend multiple rows of overlapping images shot from the one location

Stitch and blend multiple overlapping images of a plane surface shot from multiple locations

Stitch and blend flat scanned images

Correct perspective, vignetting, exposure and white balance
