Let me put it this way:

I imported a bunch of pictures in to Mac OS-X's iPhoto the other day,
and invoked the facial recognition feature. The program failed to
recognize that the majority of the faces were there at all, and although
it did recognize some pictures of me, it also presented a picture of a
mountain valley with trees and asked, "Is this a picture of Walter
Roberson?" -- and that after I had already given it over 200 pictures of
me to train on.

Perhaps you can tell me: is a mountain valley "male" or "female" ?

You expect reaction from guys only?

I also suggest for that you look at different regions of the body to detect gender ...

Right, really you need the algorithm to lift the hood and take a peak...

That's probably not available on the FEX.

Dear gender detection sharma,

> can anybody say that what are different feature in male female face

A dynamic method:
Display a picture of the secondary sexual characteristics of a woman.
Observe the dynamic reaction of the pupils.

If the pupils enlarge, the observed person is either a man in the generative age.

Limitations of the method:
1. The observed person can be a hungry baby also.
2. "Gender" is not necessarily a binary "male"/"female" descision.
3. After a certain dose of dope the pupil cannot enlarge any further.
4. Blind men - and blind women...
5. You cannot _force_ the person to focus the picture. So you can offer a beer or a prosecco as appeal. Then forget the pupil and decide based on the choice of the drink.

But beyond the scientific methods: Does anybody know a ethically valuable reason for an automatic gender classification? I don't. So why not start to spend the time for something useful?

Easier yet, and probably just about as accurate as anything else that
might be come up with:

If the candidate lifts the hood of a car to take a peak, they are more
likely male.

No, at the very least that confuses gender with sexual orientation.

It also does not take in to account the well known result of eye
tracking studies that show that women spend *more* time looking at
women's busts then men do. The traditional explanation is that they are
"comparing the other woman's bust to their own", whereas the men,
although interested, are socialized to not stare.

See my limitation 2). But let me forward the gender/sex problem to the OP.

Are there well known correlations between the time spend and enlargement of pupils? "Socialized to not stare"?!? Have these studies been performed in the USA or in Europe? What about the equilibrium of mutual showing and looking to support the evolution.

Kind regards, Jan

Well, true, at least at chests of LIVE in-person women. Digital
photos are another matter.

I once read that staring at a woman's chest for 10 minutes is the equivalent of exercising on a treadmill for half an hour. So instead of pupil dilation you could check heartbeat rate or muscle expansion *cough*.
