What changes can AI bring to our lives?At the School of Software at Huazhong University of Science and Technology, a group of young people use AI to silently provide technical support for families looking for relatives. So far, they have helped 11 missing children successfully reunite with their families, including the family of Sun Haiyang, the prototype of the movie "Dear".
Not long ago, this group of young people received a new request for help.
At the School of Software of Huazhong University of Science and Technology, the volunteers of the AI Baby Volunteer Service Team are communicating with the family tracing public welfare organizations to understand the situation of missing children, connect with the best information and repair progress. Not long ago, they received a new request for help, hoping to use AI image restoration technology to restore the ** simulation of the lost child a few years ago to the current appearance.
The idea of using AI to repair lost children** originated in 2020. At that time, Sheng Jianzhong, the captain of the AI Baby Volunteer Service Team, who was still studying for a doctorate, happened to see a message about looking for relatives, but the ** provided in the message was particularly vague. “Such a **, maybe the child is next to him and can't be recognized. I studied digital image processing, so I thought if I could use what I learned to help parents restore clear images.
However, the development of image restoration algorithms requires the construction of a huge database, and it is far from enough to rely on the strength of one person.
Sheng Jianzhong and his team spent half a year focusing on key problems, and finally developed a set of image restoration artificial intelligence algorithms, using "global restoration", "face enhancement" and "super-resolution reconstruction" technologies to solve the core problem of "face is not clear enough" in the search for relatives.
A blurry portrait** is input into the system, and after a few minutes, a repaired ** is automatically generated, and the clarity and resolution of the facial features of the portrait have been greatly improved. Parents of lost children can print their children's ** on their clothes, or print them into huge posters.
Sheng JianzhongThe image size is only 13kb, the size of the restored image is 52MB, and the resolution is 8400 10944, which meets the needs of large-scale printing.
In addition to restoration, Sheng Jianzhong and the volunteers also built a social family search model. They actively contacted the public security organs, public welfare organizations, etc. to carry out cooperation in family searching, improving the accuracy of technical investigation and family searching, and also made the repair of clear ** into family search tape, which was used on express parcels, and designed and produced family search postcards, family search short, etc., to facilitate the diffusion of family search information, and turn family family search into social family search.
Sheng JianzhongWe have made this kind of family search information into a small family search community, where there are often family members who are looking for relatives to leave messages for each other, encourage each other, and provide clues. It is also a comfort to their souls, and they will mobilize everyone to participate in the search for relatives, thus forming a community of family search with the participation of the whole society.
In the three years since its establishment, the AI Baby Volunteer Service Team has repaired more than 1,000 missing childrenHelped 11 missing children to be reunited with their families
However, the AI Baby Volunteer Service Team rarely has direct contact with the family members, and some of them are not even aware of their existence. But the members said, "Even if they don't know that we did it, we still feel very meaningful, very happy and satisfied." ”
