After the mapping is established, we train a neural network to predict face parameter from a minimal set of camera images in real time," Wei added.[br][br]Besides animating the avatars in VR, Facebook's team is also building systems that may enable people to quickly and easily create their avatars from just a few images or videos.[br][br]The Facebook team will demonstrate their RR real-time facial animation system at "SIGGRAPH 2019", which is set to be held in Los Angeles between July 28-August 1. [br][br]The researchers will present an artificial intelligence (AI) technique based on Generative Adversarial Networks (GANs) that performs consistent multi-view image style translation to automatically convert HMC infrared images to images that look like a rendered avatar but with the same facial expression of the VR user.[br][br]So many interesting features being added to the apps. Interesting isn't it?[br][br]Source: https://gadgets.ndtv.com/social-networking/news/facebook-researchers-develop-real-time-interactive-and-photorealistic-vr-avatars-2060244[br] |
