A street advert which uses facial-recognition technology to tell men from women is to be used for the first time, the Daily Mail reported.

The electronic hoarding, to be unveiled in London, plays a 40-second advertisement -- with a different message depending on the gender of the person looking at it.

Only women can view the full message, which is for a charity promoting female education worldwide. Men will just be directed to its website.

The advert guesses a person's gender by the distance between their eyes, the width of their nose and the shape of their jaw line. （点击《每日邮报》查看原文）

智能广告屏可辨识男女

       据英国《每日邮报》报道，运用辨脸技术区别男女的街头广告牌将问世。

       此电子屏幕将亮相伦敦，播放一条长达40秒的广告，然而，观看者性别不同，得到的信息也不同。

       广告由某慈善机构制作，旨在全球范围内普及女子教育，只有女性能看到屏幕上的所有信息，而男子只能看到该机构的网址。

       通过分辨双眼距离、鼻子宽度以及下巴线弧度，电子屏幕可以知晓观看者的性别。
