Apple Research Unveils GHARP for Real-Time 3D Head Animation
Key point
Apple Research has announced GHARP, a method for real-time 3D head animation using a few input images and a driving expression signal.
Apple Machine Learning Research has presented GHARP (Real-time Gaussian Head Animation from Large-scale Reconstruction Prior). This method animates 3D human heads in real time from a few input images of a subject and a driving expression signal.
The method decouples the problem into two stages: an identity stage that builds a representation of the subject’s geometry and appearance offline, and an animation stage that predicts expression-dependent residuals on top of it at runtime.
