I am given an image to load onto matlab. I have to determine the size of each face in the image in terms of pixels (i.e 48x48 pixels). Without using any matlab toolboxs, how could I find the size of the face?

You have to attach one image to help you on.

Maybe try drawpolygon to trace the face. Then get the x,y coordinates of what you drew and call polyarea.
