Computer Vision based face analysis
I'm very interested in face analysis by computer vision. This is a hot topic nowadays in computer vision research. Today's desktop computers can afford the computation required for real time processing of image sequences. And there are a lot of potential applications, among others:
- Help to disabled people in wheelchair guidance.
- More natural human computer interaction by using information in face expressions.
- Human motion capture without markers.
- Lip reading to help voice recognition.
- Building access security controls.
- Video conference at low bandwidth by face expressions
coding
+ computer animation.
research group at Universidad Politécnica de Madrid where
we
are involved in a project aimed to develop face expressions recognition algorithms.

the research topics and demos.3D Face reanimation
We have developed a prototype that is able to mimic the motion of the user using a 3D face animation model:

On the left
it is shown a video created from the output of our face analysis
system. It is able
to track the face and estimate the animation parameters of the 3D
animation model (which is a modified version of the Keith
Waters'
software on facial animation). |
Contour Tracking
As part of the research on face tracking I've done some preliminary work on contour trackingfollowing the Active Contours framework.
