How to construct 3D model using images of the face
« on: May 09, 2010, 10:40:22 PM »
does any body know how to construct a 3d face model using 4 images of the face (front, back, right side, left side). I'm using this model for a face recognition system.

You can use FaceGen. There's a free version. I can't exactly remember the limitations, but one of them was that it writes FaceGen on the forehead of the model. It exports to Blender and 3D Studio Max.

can it be implemented using eigenface in opencv? Is it possible to use convex hull type methods for this.

I'm sorry, but i have absolutely no idea what you're talking about ???
I ran across this program about a year ago, when toying around with the character generator in TESIV Oblivion. Not really went that in depth with it. But you know what they say: the truth is out there...

thanx Cristi. do you think that this constructed face model by facegen can be used for face recognition

I never tried it actually. It generates a surface, complete with texture (from the photos that you feed it). It's as usable as anything you'd be able to create in Blender or 3DSMax. I don't know about Blender, but 3DSMax can export .igs and.stl files, which you can put into any 3D software.
Just take a look for yourself. You can decide on your own how good it is for your application: http://www.facegen.com/modeller.htm

Not much... I only found out about that program out of pure curiosity, not because i actually work with this stuff. Also, i'm not that good at 3d modeling either.

does the output of faceGen can be used with opencv? I mean I need this 3D model for further recognition process in opencv.

Don't know about that, but all i can say is that Google is your friend. In other words, start finding the answers on your own. After all, it is your project, isn't it?
