Facebook and Instagram already support AR filters for Stories on their platforms.
Google Artificial Intelligence research engineers Artsiom Ablavatski and Ivan Grishchenko said: "To make all this possible, we employ machine learning (ML) to infer approximate 3D surface geometry to enable visual effects and ML pipeline for Selfie AR.”
He added: "That way we can grow our dataset to increasingly challenging cases, such as grimaces, oblique angle and occlusions. Dataset augmentation techniques also expanded the available ground truth data, developing model resilience to artefacts like camera imperfections or extreme lighting conditions."
YouTube Stories are for those creators who have more than 10k subscribers.
