Publication number: 20240161275Abstract: A method includes receiving a set of images of a child in a bed, the images acquired during a given period of time. A respective set of head postures of the child is classified from the set of images. Using the classified set of head postures, a head posture score of the baby is estimated. In response to the head posture score exceeding a predetermined threshold, a potentially abnormal child development issue is indicated and an action is taken upon the indication.Type: ApplicationFiled: November 16, 2022Publication date: May 16, 2024Inventors: Omri Levi, Tomer Shmul, Felix Vilensky, Samuel Hazak, Amir Eitan, Roy Peleg, Shalom Elkayam, Amit Ziv-Kenet, Tor Ivry
