PDL::OpenCV 0.001 has just been released. Notable changes since never:

• It supports modules highgui, imgcodecs, imgproc, objdetect, tracking, videoio
• In particular, it supports just about every class and function within those modules that are supported by the Python binding
• Where possible, all inputs and outputs are ndarrays which get wrapped into Mat, Rect, std::vector<int>, etc internally, then translated back
• There is a simplistic translation of the Doxygen docs into POD, see on MetaCPAN: https://metacpan.org/dist/PDL-OpenCV
• It includes a perldl demo which shows off basic image-processing stuff (demo opencv)

Future plans, in something like intended order:

• Support the Params classes (possibly from Perl-land as a hash-ref)
• Support more of the modules, both in the main OpenCV distribution and the "contrib" ones

The IRC channel (#pdl on irc.perl.org) is a great virtual place to come and ask questions, or just watch the GitHub messages flow by.

Please give the new release a try and report problems.
