OpenCV and Ruby on Rails

Can I use OpenCV with Ruby on Rails? If so, how can I do that? Or, what
resources do you recommend for that?

Thanks.

I know nothing else beyond the existence of this:

Thanks for your reply. I wonder if there is for Rails?

What do you mean? Rails is just Ruby right?

Take something like Nokogiri for example. It's not specific to Rails,
but it used extensively in Rails applications.

Can anyone help me to evaluate the difficulty of the task?
I need to set up a small social network site on Rails (not me myself,
but hired programmers). Users will upload images, get them transformed
and save those images in their accounts.

The difficult part: Then programmers need to write a program based on
opencv library, which transforms the image, uploaded by site's user and
return the changed image to him.

My questions are:
1)
is it practically possible to use opencv in ruby? Or you need to write
in C++ and then somehow attach code to Rails website?
2)
how much time does it take to do such work?

Sorry if the question is unclear.

Robert already pointed you to what purports to be a ruby interface to
opencv. Whether it will do what you want is another matter. Only you
or someone else who knows what you want to do with it can tell that.
Since no-one here has responded in detail I imagine no-one has
experience of it.

2)

Impossible to say without a detailed spec and time to study it. Ask
the contractors for an estimate, or hire someone to do a feasibility
study.
