tracking motion on a mouth

Jimbuck — Wed, 03 Oct 2007 21:13:32 +0000

I am creating an installation which requires me to track the motion of viewers entering the space and more specifically tracking the movement of there mouths when they move or talk. Ideally I would like to have a black bar placed over the viewers mouth when an instance occured like speaking. I have been using the some of the subtractive methods for recognizing movements but im not sure if this get’s too specific to even track. The space is all white so I figure theres a chance….after all. There’s always a possiblity with max right? Cheers everyone.

It won’t be easy, but luckily you got cv.jit library to help you
along the way.

There you’ll find cv.jit.faces object which can be of particular help.

I had one simple project where I needed to track specific parts of
the human face, so the cv.jit.faces would find the bounding box of
the face, and then using typical human face proportions would try to
locate handy points for tracking edges of the mouth, tip of the chin,
nose and eyes.

Also, try to search the list/forum for the ‘cv.jit.faces’, there were
some discussions about the object.

best,

Oh I’m sorry for this.
But, with a touch of humor, I meant if he would handle some shiny,
glossy, neon-colored lipstick to the people before they enter the
space and asked them to put this on their lips, maybe it would be
easier to track the color/movement of their mouthes.

As they say on the page: “MAXalicious Naughty and Nice”.

Very clever. I too thought it was some user-made patches. But once the splash page loaded and Carmen Elekrtified appeared in the toolbar I thought something was up. I will keep the lipstick in mind if I run into troubles….
