Guile-CV is now on Savannah nongnu.

The GNU evaluation of Guile-CV has been completed on March the 11th, 2017, but due to backlog, we've been informed then that its approval step would take another five weeks, so we decided to upload it on Savannah non gnu in the mean time, done!

Guile-CV - GNU evaluation.

A couple of months ago, we started to work on Guile-CV, a Computer Vision functional library for the Guile Scheme language, and now is the right time for it to be evaluated to be part of the GNU Project.

Guile-CV is based on Vigra (Vision with Generic Algorithms). It comprises a direct binding to Vigra_c (a C wrapper to a subset of the Vigra library), and a higher level API written in Guile Scheme.
