Developers Created AI to Generate Police Sketches. Experts Are Horrified

This program called ' Forensic Sketch AI-rtist ' developed by Mr. Arthur Fortunato and Mr. Philippe Reynaud uses a template such as age, gender, skin color, and hair style to input information to DALL E2. It is to send and display the image generated by DALL E2. It is expected to reduce the time required to create sketches when the police adopt an investigation method of creating a portrait of a suspect based on testimony from eyewitnesses.
However, experts point out that too realistic portraits may adversely affect the investigation. According to Jennifer Lynch of the Electronic Frontier Foundation, humans don't remember faces by feature, but the whole face as one. Therefore, it seems that this program, which creates a caricature based on individual features, may generate a face that is significantly different from the suspect's face. ``Unfortunately, if a witness sees the portrait, the image in memory may be overwritten with the portrait,'' Lynch said.
It has also been pointed out that image generation by AI may encourage racial and gender prejudices. Sasha Luciano, a researcher at the open source library `` Hugging Face '' on natural language processing, said, ``In general, the treatment of people of color on the Internet is very racist and unfair, and that bias is biased against AI. It's also reflected in the datasets used in .It's the marginalized groups right now that are being alienated by technology.'
“If these AI-generated caricatures were made public, they would encourage stereotypes and racial prejudices, drawing attention to the person who resembled the sketch rather than the actual culprit,” Lynch said. This could hinder the investigation,' he said. In fact, in the United States, it seems that ``identification based on eyewitness testimony'' was done in 69% of false charges overturned by DNA evidence.
In addition, developers Fortunato and others also admit that there is no index to measure the accuracy of the generated image. ``Inconsistencies in the caricature should be corrected from time to time, and iterative trials should be performed to obtain the best possible results.If this program is used, the police We have to take responsibility for sharing accurate caricatures.'
In response to this program that shortens the time to create a caricature, Mr. Lynch said, ``The problem with caricature creation is not that it takes time, but that it relies on ambiguous information such as human memory and prejudice. We can't solve this problem, and the program that appeared this time will likely make it worse.'
