Early detection methods often relied on spotting obvious visual artifacts or inconsistencies in lighting and shadows. However, as deepfake technology has advanced, these methods have become less effective. Researchers have turned to , training models on vast datasets of both real and fake videos to recognize the subtle patterns and statistical anomalies that betray a forgery. This has led to the development of specialized networks designed for the forensic analysis of video content.
