Researchers in Canada's Simon Fraser University (SFU) School of Interactive Arts and Technology (SIAT) have developed a method of employing artificial intelligence (AI) to better obscure the faces of anonymous individuals in news reports.

SIAT's Steve DiPaola says the method involves an updated model of pixelization incorporating “more than 1,000 years of artistic technique,” which is used to teach the AI "to lower the outer resemblance and keep as high as possible the subject's inner resemblance—in other words, what they are conveying and how they are feeling."

The system utilizes five levels of AI processing to simulate a painter that uses art abstraction to "repaint" each frame of video.

DiPaola says the system’s ability to anonymize faces “while retaining a strong degree of emotional connection or resonance should result in better final product for anonymized video.”
