Hi!
I use Viola's face detector - http://www.mathworks.com/matlabcentral/fileexchange/29437-viola-jones-object-detection
to detect face region. it is nicely giving detected face region. but i need to separate that detected region. is there any way to separate that square which include face region.
Thanks.

I am assuming that you are using the STEP method of VISION.CASCADEOBJECTDETECTOR that returns a bounding box.
You could just use the bounding box data to crop out the face from the image.
For example, if I is the RGB image and bounding box is [x,y,w,h], you could do:
croppedFace = I(x:x+w, y-h:y,:);
