Algorithms Can Make You Pretty

Posted by timothy on Thu Oct 09, 2008 05:48 PM
from the too-late-for-me dept.
caffeinemessiah writes "The New York Times has an interesting story on a new algorithm by researchers from Tel Aviv University that modifies a facial picture of a person to conform to standards of attractiveness. Based on a digital library of pictures of people who have been judged 'attractive,' the algorithm finds the nearest match and modifies an input picture so it conforms to the 'attractive' person's proportions. The trick, however, is that the resultant pictures are still recognizable as the original person. Here's a quick link to a representative picture of the process. Note that this is a machine-learning approach to picture modification, not a characterization of beauty, and could just as easily be used to make a person less attractive." Note: As reader Trent Waddington points out, the underlying research was mentioned in an earlier story as well.

    I seem to remember a Discovery channel special with John Cleese that discussed the math behind good looks. I understand this is a learning algorithm but I wonder how much easily this could be accomplished just by enforcing the golden ratio [intmath.com] on a face. I think science has come up with a more exact ratio for faces. Honestly, the sample picture looks like they made her face shorter and easily more attractive that way.

    Of course, beauty is in the eye of the beholder and when you get old looks fade and all those cliched adages.

        I'm not here to argue which picture is prettier but I know for sure that you can't make conclusions about her personality just by the way she looks. That's sexism, plain and simple.

        While I agree that making guesses at someone's interests based on a headshot is superficial, we disagree on the definition of sexism. The poster was comparing two women, and not contemplating offering a job to either one (as far as I can tell).

        Either that, or we disagree on the definition of women.

        Although there is something intellectually repellant about it, you are very naive if you think that you don't, or can't, make certain judgments about people based upon appearance.

        For one thing (and generalising horribly), from a biological point of view how attractive you find someone is likely to have some correlation to whether they are likely to be a good (i.e. successful) match for you, or for propagating your genes.

        From a social point of view, the way someone looks and presents themself also communicates a large amount of information to you non-verbally. To me, the 'after' picture has the subtle look of someone who is attempting to present themself in conformity to a certain standard, which is not a standard I find particularly compelling.

        Finally, is it impossible to think that someone who is conventionally pretty might be exposed to a different set of experiences to someone who is not regarded as such? This might natually have some impact on personality.

        All of the above are generalisations. I totally agree that ideally one should not make snap judgments about people based on appearance. Nevertheless, I maintain that everyone does it, and that it is not entirely invalid (from a logical, not moral, point of view).

        As for 'sexism', it is nothing of the sort. If it's anything, it's reverse discrimination against blandly pretty people, which is probably not all that high on the list of terrible things happening in the world today.

      I liked the woman on the left (original) better, but I am a statistical anomaly. That doesn't mean my opinion of beauty is any less valid, it just means my opinions aren't shared with the majority of human beings. The person's culture has less of an effect on a person's opinion of beauty than you claim is the point that the science is trying to prove.

    I couldn't sense any difference between the two pictures for most of the guys, but the pictures of the women seemed significantly different. Maybe I'm just weird, or maybe, as a guy, I recognize the subtleties of women's faces better, or maybe I recognize the differences more readily because I look at a lot more women than men.

    Anyone else notice the same thing? As well, did any women notice the differences in the men a lot easier than in the women?

    The brown-eyed girl looks plain now. Not ugly, just plain. The before picture had a more expressing face.

    The pictures on this page (http://www.cs.tau.ac.il/~tommer/beautification2008/) are absolutely lame. The "before" pics had people in a neutral to a tiny bit of sad face(look at the lips). The new pics simple lift the corners of the lips and tada, better results. That's not better, that's cheap. Since the days of tell-sell I have realised that the before/after contruct was purely based on non-smiling/smiling people because it's that much of a change. This algorithm fails and should not be touted as the best thing since sliced bread.

    Also, it makes Woody Allen look like someone who is 90.

    It does much the same, but leaves the face alone and photoshops it onto an image taken from a fashion magazine.

    It's still recognizable as the same person, but they look a lot better.

    This technique is so powerful, that if you choose the right magazine (eg, Playboy, Hustler etc) that the test subjects don't even notice if you cut the original face out badly.

    Three out of Four test subjects said "What Face" when asked about this irregularity and two left the test early with the new pictures, no doubt impressed by the quality of my algorythm.

    So a bunch of Germans and Jews got together and sorted through a bunch of people to determine which ones were better?

    I've seen the full video and looked at the article from the SIGGRAPH materials. All of the "after" pictures except one did look more or less better than the "before" picture, but there was one consistent change I noticed -- many of the subjects, especially among the female photos, appeared to be frowning or pouting in the original picture, and the modified picture turned up the corners of the mouth into more of a smile.

    This tells me that simply smiling can enhance one's attractiveness a great deal!

      personally, i find the faceresearch.org demo [faceresearch.org] posted on Slashdot a while back the most interesting. unlike this algorithm, it actually presents some interesting findings about the psychology of aesthetic beauty.

      rather than manipulating a single photo to make that person more "pretty." it allows you to average different people's head shots. and the result of this research seems to show that our perception of beauty is based on the mean range of facial geometries we're exposed to. we naturally find faces that are the most "average" attractive. but different populations have different averages, so there are still cultural differences.

      another way to look at it is that instead of looking for features that define beauty, we really just have an aversion to faces that deviate too much from the cultural norm as defined by the average range of facial configurations. now, everyone has unique features that distinguish them from others, and everyone deviates from the population average in some respect, but some show a greater deviation than others, which may indicate their genetic fitness. and so our psychological attraction to average faces is an evolutionarily learned trait to help us pick the most genetically healthy individuals to mate with.

      but what's interesting is that if you mix several very different faces that don't meet conventional standards of beauty, you will actually get a very attractive face as a result (try this in the demo by picking the ugliest faces out of the gallery to mix). this is probably because even though "ugly" people deviate largely from the cultural average, they all deviate in different ways, so it doesn't take two beautiful individuals to produce an attractive average.

      a corollary to this effect is that a couple with drastically different looks will give birth to very attractive children. which actually works out perfectly with another evolutionary trait--that of opposites attracting. human beings (and perhaps other mammals as well) are attracted to individuals with a very different histocompatibility index to themselves. that is to say, we are attracted to individuals which are very genetically different from ourselves. we can detect people's histocompatibility with our own based on their body scent. and double blind studies have found that men and women find the body odors of individuals whose Major Histocompatibility Complex (MHC) was the most different from their own. this is to ensure that their offspring will receive a diverse set of genes, which leads to a more robust immune system and prevents inbreeding.

      now, my personal theory is, men and women don't just find partners with complementary MHCs to them based on scent alone. facial features can also be an indication of genetic differences. so this may also lead to individuals being attracted to people who have very different facial features from themselves. and since the average of two drastically different faces produces a more average face, this also leads to better looking children.

        Mirrored yes. But more symmetric does appear more attractive.

        From the sample it looks like their algorithm almost completely disregarded several opportunities for increasing symmetry and improved the face in other ways.
