GNU Guile-CV 0.1.9 released

[David Pirotte]

Hello,

GNU Guile-CV 0.1.9 is released.


* About

Guile-CV - Image Processing and Analysis in Guile - is a Computer Vision
functional programming library for the Guile Scheme language.

Based on Vigra (Vision with Generic Algorithms - a C++ image processing
and analysis library), Guile-CV comprises a direct binding to Vigra C (a
C wrapper to most of the Vigra functionality), enriched with pure Guile
scheme algorithms, 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.

Vigra C >= commit a2ff675f4 April 15, 2018

new interface vigra_nonlocalmean_c (introduced in Jan 2018), has an
argument that has been renamed;

the vigra_medianfilter_c function (updated in Jan 2018 as well) takes
an additional 'out-of-bound strategy' argument.

*** New interfaces

im-median-filter
im-median-filter-channel
im-nl-means
im-nl-means-channel

*** Bug fixes

latex-pdftoppm

in the module (cv support latex) - undocumented but quite usefull
procedure, to 'prepare' text to be added to images (see im-compose) -
the optional keyword [#:res 72] argument was actually not used in the
core of the procedure, fixed.

[*] 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-0.1.9.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
