      Computer Tells Real Smiles from Phonies

      電腦能分辨出假笑

      Is that person really glad to see me? Or are they just being polite? Some people struggle to distinguish a perfunctory grin from a truly happy smile. And computers have found this task even more difficult—that is, until researchers trained a program to detect when a smile is genuine.

      他見到我真的高興嗎?還是只是出于禮貌?有些人很難區分敷衍的微笑和真正快樂的微笑。而計算機對此進行區分更加困難——也就是說,研究人員需要研發出一個程序來檢測一個微笑何時是發自內心的。

      Visual computing researchers at the University of Bradford in the U.K. started with software for analyzing a changing facial expression. This program can examine a video clip of a human head and identify specific details around the eyes, cheeks and mouth. Then the program tracks the details moving relative to each other as the face smiles.

      英國布拉德福德大學的視覺計算研究人員從分析面部表情變化的軟件開始。這個程序可以檢查人類頭部的視頻剪輯,識別眼睛、臉頰和嘴巴周圍的特定細節。然后,當人臉微笑時,程序就會追蹤彼此之間相對移動的細節。

      Next, the scientists had their program evaluate two sets of video clips. In one, subjects performed posed smiles. In the other, they watched a film that inspired genuine displays of emotion. The program calculated the differences among the subjects’ faces during the two clips. And it turns out that your mouth, cheeks and eyes move differently when you’re faking that smirk.

      接下來,科學家讓他們的程序評估兩組視頻剪輯。在其中一個實驗中,受試者擺出假笑的姿勢。在另一個實驗中,他們觀看了一部激發真實情感的電影。該程序計算了兩段視頻中受試者面部表情的差異。事實證明,假笑時,你的嘴、臉頰和眼睛的運動方式與發自內心的笑是不同的。

      In particular, the muscles around the eyes shift 10 percent more for a real smile than they do for a fake one. These results are in the journal Advanced Engineering Informatics.

      特別是,眼睛周圍的肌肉在真實微笑時比在虛假微笑時多移動10%。研究結果發表在《高級工程信息學》雜志上。

      The researchers suggest their work could improve a computer’s ability to analyze facial expressions and thus to interact more smoothly with humans. But their real accomplishment is in proving Tyra Banks right: “You have to smile with your eyes.”

      研究人員表示,他們的工作可以提高計算機分析面部表情的能力,從而更順暢地與人類互動。但他們真正的成就是證明泰拉班克斯是對的:“你必須用眼睛微笑。”
