MUMBAI: With the overwhelming popularity of Stories feature on social media platforms, the companies are leaving no stones unturned to make it more attractive. Now, Google is rolling out support for its advanced Augmented Reality (AR) effect tools for YouTube Stories while its rival Facebook and Instagram already support AR filters for Stories on their platforms.

The new feature will allow users to add animated masks, glasses, 3D hats and more such objects to their selfies. "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," Google Artificial Intelligence research engineers Artsiom Ablavatski and Ivan Grishchenko wrote in a blog post on Saturday.

"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," the post added.

The company has also claimed that it will use improved "anchoring" process with the new AR effects to make them look more real and responsive. According to the post, it uses a unique set of technologies "that can track the highly dynamic surface geometry across every smile, frown or smirk."

However, YouTube Stories is not available to every user yet as the tech giant launched the feature last year but only to creators with more than 10k subscribers.
