hello
i want to know how can i extract the face from a given image; when i input an image for the whole body how can i extract the face and just the face and save the extarction information as a new image?

Well sort of. But you didn't say if you're using an algorithm, which
one is it, or if you even looked. I believe there are several face
detection apps uploaded to the file exchange. Have you looked at
them? Have you contacted the authors? Have you done a more general
web search? There must be hundreds of algorithms - I have no idea
which one is best. I'm sure each one that is published will claim to
be the best. If you want a list of them all, go here:
http://iris.usc.edu/Vision-Notes/bibliography/contents.html
and look at section 21:
"21 Face Recognition, Detection, Tracking, Gesture Recognition,
Fingerprints, Biometrics "

If you have a question related to MATLAB programming specifically,
rather than an image processing algorithm, then come back here with
your code.

Hi Fida,

I suggest you to look into MATLAB Central as a start. Here is something that
is similar to what you are asking for:

http://www.mathworks.com/matlabcentral/fileexchange/11073-face-detection-system

If your question is however about cropping the face from an image to store
it somewhere else for preprocessing purposes, then an easy way to do this
would be using

Adobe Photoshop's Lasso Tool as a mean to do that.

Hope this helps,
Murad
