Its looks just too weird to be true. That’s one clue casting doubt on a recent video posted on TikTok and seen by at least a million viewers that reported a tiger at the Phoenix Zoo was shot for being too human-like. Imperfections in the video make it relatively easy to discern as a fake, says Subbarao Kambhampati, a professor in the School of Computing and Augmented Intelligence, part of the Fulton Schools. But he cautions that other videos being made with more advanced artificial intelligence, or AI, technology, than that used in the zoo tiger video are going to make it more difficult to discern real from false video images in the future.
