With the continuous advancement of artificial intelligence technology, the difficulty of forging images and videos has decreased significantly, making the deepfake phenomenon increasingly severe. Identifying these false contents has become an urgent issue to address. Recently, a research team from Binghamton University conducted an in-depth discussion on this topic, using frequency domain analysis techniques to reveal the characteristics of AI-generated images, thus helping people identify false information.
