Mobile Computer Vision functionality advice

I've recently joined a Unity project publishing to Android and iOS. I require computer vision functionality & tools (e.g. face detection).

FastCV SDK looked promising but has no Unity plugin or iOS support.
FaceApi looked promising (but limited to face detection?)
Vuphoria does not have the functionality I need.
Compiling an openCV plugin myself to import sounds a difficult and error prone route given the platform(s) and I am told performance will suffer.

Any advice / suggestions / pointers on where to look?

http://answers.unity3d.com/questions/195133/Mobile-Face-Detection.html posted a similar question (without solution) a year ago -- have things changed since then? Thanks!

to be honest .. I just don't think Unity is relevant to or suitable for facial recognition.

Just do it as an ordinary XCode native iOS app.

face recognition is totally built-in to the cocoa/XCode milieu.

(you've seen all the silly little apps that notice where people's eyes are, etc.)

I just don't see any relevance to Unity, a game engine.

it would be like if this was a cocoa-XCode list an you said "how do I make GTA?" Everyone would be like "Huh, to make a 3D action game, why don't you just use Unity which is built for making 3D action games?"

It's extremely likely you're going to be wanting to use Graphic Chip Power for processing, and that's all iOS all the way.

$$anonymous$$gest you go to StackExchange and ask.

By all means, per $$anonymous$$r Turing, you could do anything at all you want in Unity, using Unityscript, and "GetPixel" and so on (!) - but it just seems wholly outside the purview of Unity.

($$anonymous$$y $$anonymous$$ain Interest is machine vision, I'd love it if there was something as let's say easy and popular as Unity, in relation to vision woes.)

Thanks for the reply and information here.

I am joining an AR project that is already underway making use of Unity and specifically the Vuforia plugin, hence the engine choice. The project now requires some CV functionality. Sorry that I did not make this clear. I'm afraid, for this reason, the engine choice is beyond my control but I take your points on board.

I will feed back any interesting StackExchange suggestions to this thread.

I was just wondering if the OP or anyone else has made any progress in this area? I find myself needing the exact same thing (i.e. computer vision functionality in a Unity project) and came up with the same limitations as listed in the original post from 4 months ago.
