Li also prefers working with graduate students because of their passion and energy for getting things done. He said a university setting was his best choice for creating something “foreign and long-term” because there was no pressure to turn his research into a product.
Li joined USC three years ago as an assistant professor to start a research lab. “They evolved to all real-time facial things that we see nowadays - for sure the features on the iPhone X.” “These two components were sort of key,” Li said. Non-rigid registration is a concept that uses an algorithm to smooth out the deformations in depth scans so it matches the person’s movement as much as possible. Two seminal components were conducive to the technology behind Animoji: facial tracking using structured-light 3-D scanners and non-rigid registration. “One of the most appealing features was markerless facial performance capture,” Li said. Faceshift is a facial motion capture software that uses Microsoft Kinect’s depth-sensing technology to capture movements in real time. Li’s contribution began in 2015 when Apple acquired Faceshift, a tech startup he co-founded in 2011. USC assistant professor of computer science Hao Li was one of the developers who brought this idea to life, as he conducted research on facial motion capture that later contributed to the iPhone X’s animated emoji, or “Animoji,” feature. Upon its debut, facial recognition was among the iPhone X’s most talked-about features.
