P图3小时,1秒现原形!Adobe发布“反向PS”利器丨说英闻
很多人都说,这是一个看脸的世界,网上发照片前先修图也似乎已经成为新的“社交礼仪”。
近日,Adobe为自家的修图神器Photoshop打造了一项新技术,可以识别出人像照片中被修改过的部分,还能恢复原图的模样。
对此,相信许多人的第一反应是:为什么要研发这样“打脸的技术”??
开发P图神器是它,率先扛起反P图大旗的也是它,Adobe这波操作可谓:
这项研究是专门针对使用Photoshop的面部识别“液化”(Face-Aware Liquify)工具进行编辑而设计的。
Liquify可谓是支撑Photoshop修图神器的一项重要功能,它能够调整人像的面部形状、五官以及改变面部表情。
下面来看下“反P图”的效果:
简单来说这项技术能辨别出哪张照片修过了,修了哪里,还能还原“最初”模样。再来看个例子:
当然,这个技术并不是通过获得你PS后台的修改记录,或者是获得你内部文件,而是靠机器学习来辨识造假的图片。
研究人员编写了Photoshop脚本,从互联网上抓取数千张图片并使用“面部感知液化功能”,形成了图像训练集。
The researchers created an extensive training set of images by scripting Photoshop to use Face Aware Liquify on thousands of pictures scraped from the Internet.
据了解,经过训练之后算法非常有效。人类志愿者识别出图片真伪的正确率只有53%,算法的正确率却高达99%。
目前“一键还原”这种神奇功能还没有实现,而且该功能只能用于经Photoshop处理过的照片。
Adobe公司在博客中表示:
我们对Photoshop和其它Adobe创意工具在世界上的影响力感到很自豪,但同时也意识到我们科技产生的道德问题。
While we are proud of the impact that Photoshop and Adobe’s other creative tools have made on the world, we also recognize the ethical implications of our technology.
不过Adobe此举可让国内的网友们炸了锅。很多网友认为在“全民P图”的年代,这可能是一款牛却不讨喜的技术。
目前Adobe公司没有打算立即将这项最新成果进行商业化。
As of now, Adobe does not plan to commercialize the prototype.
如果将来“反P图”技术普及,你会支持吗?

Daily Mail:
Adobe researchers have developed an AI tool that could make spotting 'deepfakes' a whole loteasier.
The tool is able to detect edits to images, such as those that would potentially go unnoticed to the naked eye, especially in doctored deepfake videos.
It comes as deepfake videos, which use deep learning to digitally splice fake audio onto the mouth of someone talking, continue to be on the rise.
Tech Crunch:
Using Photoshop and other image manipulation software to tweak faces in photos has become common practice, but it’s not always made clear when it’s been done. Berkeley and Adobe researchers have created a tool that not only can tell when a face has been Photoshopped, butcan suggest how to undo it.
