However, Verdoliva of Frederick II University of Naples warned: "Generation methods keep improving over time and show fewer and fewer synthesis artefacts, so I would not rely on visual clues in the long term."įor example, in March 2023, realistic hands are still difficult to generate. It is these inconsistencies and artefacts that must be scrutinised, as in a game of spot the difference," said Terrasi of Draft & Goal. "Some characteristics, often the same ones, pose a problem for AI. These defects are the best way to recognise a fabricated image, specialists told AFP. ![]() This method makes it possible to find the source of images that allegedly show a violent altercation between former US president Donald Trump and police officers arresting him.ĪI-generated image created on Mausing DALL-E and the phrase: "Brad Pitt in Paris, photo, shops in the background, 4K"ĭespite the meteoric progress in Generative AI, errors still show up in AI-generated content. In some cases, the creator may have said it was AI-generated and indicated the tool used.Ī reverse image search can help by seeing if the picture has been indexed in search engines and finding old posts with the same photo. Go back to the image sourceĮxperts say one important clue is finding the first time the picture was posted online. "Unfortunately you cannot rely on metadata since on social networks they are completely removed," AI expert Annalisa Verdoliva, professor at the Frederick II University of Naples, told AFP. A picture's metadata, which can sometimes reveal the source of an AI-generated image, is not helpful either. That is why manipulation detection software works poorly, if at all, in identifying AI-generated images. Vincent Terrasi, co-founder of Draft & Goal, a startup that launched an AI detector for universities, added: "The AI mixes these images from its database, deconstructs them and then reconstructs a photo pixel by pixel, which means that in the final rendering, we no longer notice the difference between the original images." "There are thousands/ millions of photos that were used to learn billions of parameters." ![]() "When AI is generating pictures (from scratch), there is in general not a single original image from where parts are taken," David Fischinger, an AI specialist and engineer at the Austrian Institute of Technology, told AFP on March 21. #midjourney #midjourneyv5 /dJoZXGrbRy - Cryptonoo₿ From 100K to 0 March 19, 2023 L' #ia #photo a fait des progrès démentiels en très peu de temps, désormais le #fake sera la norme sur les #reseaux, doutez de ce que vous voyez par défaut, plus le choix. But the results are mixed and can sometimes be misleading, according to tests by AFP. Others portrayed French President Emmanuel Macron as a garbage collector as rubbish was mounting on Parisian streets amid mass strikes over controversial pension reforms.Īlthough most creators clearly state these widely shared images are fabricated, other photos circulate with no context or are presented as authentic.ĭevelopers have launched tools such as Hugging Face to try to detect these montages. Many people use these tools for humorous or artistic purposes, but others rely on them to fabricate images of political news.įor example, a flood of AI-generated images circulated on Twitter after the meeting between Putin and Xi on March 20, 2023. Recently developed AI tools such as Midjourney, DALL-E, Craiyon or Stable Diffusion can generate an infinite number of images by drawing on massive databases. ![]() How can you tell a genuine image from a computer-generated one? Visual inconsistencies and a picture's context can help - but there is no foolproof method of identifying an AI-generated image, specialists told AFP. Some ultrarealistic images of news events have already been mistaken for real ones and shared on social media platforms. Donald Trump behind bars? Russian leader Vladimir Putin kneeling before his Chinese counterpart Xi Jinping? You might have seen what seem to be realistic images like these circulating online, the result of rapid advances in artificial intelligence known as Generative AI.
