Autostitch is the world's first fully automatic 2D image stitcher. Capable of stitching full view panoramas without any user input whatsoever, Autostitch is a breakthrough technology for panoramic photography, VR and visualization applications.

This is the first solution to stitch any panorama completely automatically, whether 1D (horizontal) or 2D (horizontal and vertical).
