AUTOPANO-SIFT(7) Overview AUTOPANO-SIFT(7)
NAME
autopano-sift - Automatic panorama stitching package
INTRODUCTION
The autopano-sift package contains a number programs to ease the cre-
ation of panoramic images. A tedious task in panoramic image creation
from many individual images is the aligning of the images so they fit
together. This is normally done by using control points which give
information about shared image features. For example, image two images
of a church. Lets assume both images overlap so that the rooftop of the
church is visible in both. By telling a panorama software that the roof
is in both images at a specific position the images can be aligned. At
least three control point pairs between every two images are required
usually.
The manual work of creating this control points can be immense. Espe-
cially for panorama images holding more than one line of images there
is a huge number of possible overlaps.
The autopano-sift package can automatically create control point pairs
by using a combination of sophisticated algorithms and models. For most
feature-rich images it works very well, often outperforming humans in
coverage, precision and speed.
In the following, the individual utilities are introduced. If you want
a quick start, try the autopanog(1) GUI frontend.
DESCRIPTION
autopanog The GTK# GUI frontend for generating and matching SIFT key-
points. As a user wanting to stitch panorama images, this is all you
will ever need. See autopanog(1)
autopano The keypoint matching program. It can take SIFT keypoint files
as input and produce PTO output files. See autopano(1)
generatekeys The SIFT keypoint extraction program. Takes an image from
you, and gives keypoints back. Optionally can downscale the image to a
given resolution, so your memory size is cared for. See generatekeys(1)
showone Show the SIFT keypoints overlayed over the source image. Use
includes debugging and tuning of SIFT parameters and to get an impres-
sion how well spread the keypoints are. See showone(1)
showtwo Do simplistic matching of SIFT keypoints between two images,
without geometric model. Use includes representing general matching
quality. Optionally filter only a given number of "best" keypoint
matches. See showtwo(1)
BUGS
If you find any bugs in the programs, please mail the author.
