Artists have traditionally made these images by altering old photos of the suspect – adding wrinkles, hair loss and other common aspects of aging. But in recent years there has been a move towards using computer systems that employ machine learning, a much more sophisticated and formalized way of changing people’s faces.
We can’t predict with certainty how a person will look years after their last available photo, but these images can still help police. Here’s how the technology has developed.
