There's a reason why people 100 years ago looked miserable. A new study has revealed how our smiles have evolved in photographs as a direct result of improving technology.The research was done using a new data-mining tool, which can reveal patterns in anything from phone conversations to behaviour on social media.
100年前的人看着那么悲催是有原因的。随着技术的不断改进,一项新研究向人们揭示了照片中的"笑容进化史"。通过应用新的数据处理工具,这项研究得以揭示从电话谈话到社交媒体中的一切规律。
Ginosar looked at 150,000 yearbook photos as part of the study.After deleting photos that weren't face-on, she was left with around 37,000 images from 800 yearbooks in 26 states.
吉诺萨研究了15万张年鉴里的照片。去掉非正脸照片后,她留下了从26个州800本年鉴中找到的3万7千多张照片。
She then put the photographs together based on gender, and then decade, before they were blended into on another to create an 'average' face from each period.After analysing the images using her data mining tool, she found the most obvious difference between was the evolution of the smile, which gets broader as the years go on.
她先把照片根据性别和年份拼在一起,然后将这些照片重新排列,并从每个时期找出一张"大众"脸。通过运用数据处理工具解析图片,她发现其中最明显的区别莫过于微笑的演变,随着年代不断靠近,人们的微笑也越来越开怀。
