Hello, GNU Guile-CV 0.1.4 is released. This is the first public release of GNU Guile-CV, earlier releases were made available to GNU evaluators and Savannah hackers only. * About Guile-CV is a Computer Vision functional programming library for the Guile Scheme language. Guile-CV is based on Vigra (Vision with Generic Algorithms). It comprises a direct binding to Vigra_c (a C wrapper to some of the Vigra functionality), and a higher level API written in Guile Scheme. http://www.gnu.org/software/guile-cv/ * Download Here are the compressed sources and a GPG detached signature [*]: http://ftp.gnu.org/gnu/guile-cv/guile-cv-0.1.4.tar.gz http://ftp.gnu.org/gnu/guile-cv/guile-cv-0.1.4.tar.gz.sig This released was bootstrap with the following tools: Autoconf 2.69 Automake 1.15 Makeinfo 6.3 Guile-2.2 2.2.2.3-0c102 Guile-Lib 0.2.5 Vigra from the source last commit here: ab154c5 - Mar 21, 2017 Vigra_c from the source last commit here: 0885303 - Feb 3, 2017 * Changes since 0.1.3.2 ** Dependencies New (or previously unchecked) dependencies: Makeinfo >= 6.3 Latex any modern latex distribution documentclass: standalone packages: inputenc, fontenc, lmodern, xcolor, booktabs, siunitx, iwona ** API change: im-properties: renamed im-features im-*grey* procedures and methods: renamed im-*gray* dito for arguments GREY -> GRAY in the documentation colour -> color COLOUR -> COLOR: both in the source code (arg and kw arg names) and in the documentation f32vector-* procedures use #:key, not #:optional im-padd im-padd-channel accept a #:color optional keyword argument f32vector-multiply renamed f32vector-matrix-multiply ** New procedures: f32vector-inverse f32vector-reduce f32vector-mean f32vector-std-dev im-add im-add-channel im-subtract im-subtract-channel im-multiply im-multiply-channel im-divide im-divide-channel im-inverse im-inverse-channel im-compose im-compose-channels im-particles im-particle-clean im-histogram Please report bugs to bug-guile-cv@gnu.org For the time being, GNU GUile-CV uses Guile's mailing list, join guile-devel@gnu.org and #guile on Freenode for discussions. David [*] 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-0.1.4.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
