* About

[[http://www.gnu.org/software/guile-cv/][GNU Guile-CV]]
Image Processing and Analysis in [[http://www.gnu.org/software/guile/][Guile]]
a Computer Vision functional programming library

Guile-CV is based on [[http://ukoethe.github.io/vigra/][Vigra]] (Vision with Generic Algorithms), enhanced
with additional algorithms (Image Textures, Delineate, Reconstruction
and many more), all accessible through a nice, clean and easy to use
high level API.

Guile-CV is natively multi-threaded, and takes advantage of multiple
cores, using high-level and fine grained application-level parallelism
constructs available in Guile, based on its support to POSIX threads.

[fn:1]

  Use a .sig file to verify that the corresponding file (without the
  .sig suffix) is intact.  First, be sure to download both the .sig file
  and the corresponding tarball.  Then, run a command like this:

	gpg --verify guile-cv-0.4.0.tar.gz.sig

  If that command fails because you don't have the required public key,
  then run this command to import it:

	gpg --keyserver keys.gnupg.net --recv-keys A3057AD7

  and rerun the 'gpg --verify' command
