Adobe revealed that it is developing a method to detect photoshopped or manipulated photos. The computer software company recognized the ethical implications of its technology.
Its software, Adobe Photoshop, has been the main source of manipulated images. To counter the epidemic of fake news, the company began developing tools that can detect if the photo is photoshopped. The tools will then reverse the alterations to reveal the original photo.
It is the first time that Adobe developed ways in preventing misuse of its products. But it has image recognition tools built into Photoshop. These tools can prevent scans or photos of bank notes from being opened. However, the result is not infallible.
This latest detection tool is designed using a hyper-specific task. It detects each time a face is warped and manipulated through the software’s Face Aware Liquify tool. This tool makes it easy to change the eyes, mouth or entire face.
“This new research is part of a broader effort across Adobe to better detect image, video, audio and document manipulations. Past Adobe research focused on image manipulation detection from splicing, cloning, and removal, whereas this effort focuses on the Face Aware Liquify feature in Photoshop because it’s popular for adjusting facial features, including making adjustments to facial expressions. The feature’s effects can be delicate which made it an intriguing test case for detecting both drastic and subtle alterations to faces.”
This new tool is the result of the company’s collaboration with UC Berkeley scientists who use machine learning to detect automatically each image of faces has been photoshopped.
Last year, Adobe’s engineers developed an AI that detects photoshopped media through cloning, splicing and removing some objects.
How Does It Work?
“By training a Convolutional Neural Network (CNN), a form of deep learning, the research project is able to recognize altered images of faces. 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.”
Adobe is not planning to make a commercial version of such a tool. But it is one of the efforts that the company makes to detect manipulated photos, videos, and audios. The company recognized that fake content is a pressing issue. With the help of this tool, it could spot edits made using the Liquify tool.
Compare to human eyes:
“Those human eyes were able to judge the altered face 53% of the time, a little better than chance. But in a series of experiments, the neural network tool achieved results as high as 99%.”
Adobe’s mission is to serve consumers. It will continue to give tools that allow creators to bring their ideas to life. But it will also work across numerous research projects to verify the authenticity of digital media made using its products. In that way, it will discourage misuse.
This Adobe tool that detects manipulated photos and videos is not foolproof. Most people could discern whether the photo is fake or not. However, they still love to share them on social media.
