This is my first attempt at achieving Augmented Reality using OpenCV instead of AR Toolkit methods... an idea I have had rattling around for quite awhile. I think that OpenCV has greater potential, and a wider library than AR Toolkit, and allows me to set specific tracking points "on the fly" instead of having to rely on "preprinted" sheets.... It can also possible be set for color and facial recognition among other things.
This is different than "Optical Flow" in that optical flow can only track general movement patterns, whereas this is tracking specific points... in this case, my index finger.
Yesterday, Chris Wright mentioned the idea of "squishing" objects with fingers, and this was a quick test to see if I could achieve something like that... this uses Kineme3D.
I derived x/y by "clicking" with the mouse, on the tip of my index finger... that set a tracker; extremely simple. Then I tied the x/y coordinates to a Kineme3D tools, to achieve the warp.
