Looks like you got some good answers, but my first thought was to look to see if there was an OpenCV interface on CPAN. Unfortunately, there is not and it seems like you don't need that level of sophistication. I am just mentioning it here in case some generous soul reads this and gets inspired to create such an interface for Perl using one of the nice FFI options we have. =D
