1.WHAT ITALIAN POLICE DO WITH ML?
Italian police recently arrested a suspected sicilian mafia leader, matteo messina denaro, who is on the run. for older images, they tend to use computer systems that employ machine learning to modify people’s faces in a more sophisticated and formal way.

2.WHAT IT DO ?
Use the difference of two average images. i combined photos of multiple people matching the target for age, gender, and overall skin tone to create an average “young” image. a computer calculated the difference between two images of her with features such as gray hair and wrinkles, and applied the difference to the image of her younger face, resulting in an image that looked older.

3.WHY ML IS HIGHLY LIKED IN THIS FIELD?
Such systems may only be able to learn the average changes in faces with age, but they are also capable of more detailed learning. the results can be compared to known patterns of faces, and different researchers compete to minimize the difference between predictions and reality. there is also an app.
a significant role for computer facial recognition, if society chooses to accept it, could be to find the individuals we’ve been looking for for so long, so finding the best ways to do this will require more it suggests that more research may be needed.
