Google Working To Identify Your Sex

Google researchers are working hard to complete an algorithm that can detect the gender of persons in images. Google says that the most popular images searched for in Google Images are those of people, primarily celebrities, and labeling them all by hand is far from possible. Google is using an Adaptive Boosting meta-algorithm to allow it to identify the sex of persons in a photo from a low resolution grayscale picture of the face.
Google says it has 80% accuracy with 10 pixel comparisons, 90% accuracy with less than 50 pixels, 93% on a 20×20 pixel image. As the article mentions, one possible application could be to scan for adult content in images, too. After all, if you can tell the difference between a man and a woman, you can probably identify a boob, too?
