| etc) in a portrait image.

face recognition software does some circle detection to find and help
decode the face.   Unfortunately IM does not do this (yet)


| The images are taken on white background but it may be a little gray and
| have shadows. The ideal result would be an image that has in black thick
| borders of the edges of the faces, the hair, eyebrows and a minimal details
| of nose and mouth. Everything on a white background. Anybody can help with
| that ?
| 
| 2) remove the background and make that part of the image transparent. Again
| it is still a portrait with a white-ish background.

See  IM Examples...
