All AI Do Is Win: NVIDIA Research Nabs ‘Best in Show’ with Digital Avatars at SIGGRAPH

” Making digital avatars is an infamously challenging, tiresome and expensive process,” stated Bryan Catanzaro, vice president of used deep knowing research study at NVIDIA, in the presentation. However with AI tools, “there is a simple way to create digital avatars genuine individuals along with animation characters. It can be utilized for video conferencing, storytelling, virtual assistants and lots of other applications.”

The display, among the most anticipated events at the worlds largest computer graphics conference, held virtually this year, commemorates advanced real-time jobs covering video game technology, enhanced reality and scientific visualization. It included a lineup of jury-reviewed interactive projects, with presenters hailing from Unity Technologies, Rensselaer Polytechnic Institute, the NYU Future Reality Lab and more.

The demonstration included tools to produce digital avatars from a single photo, stimulate avatars with natural 3D facial motion and transform text to speech.

In a turducken of a demo, NVIDIA scientists stuffed four AI models into a serving of digital avatar technology for SIGGRAPH 2021s Real-Time Live display– winning the very best in Program award.

Broadcasting live from our Silicon Valley headquarters, the NVIDIA Research team presented a collection of AI models that can create realistic virtual characters for tasks such as bandwidth-efficient video conferencing and storytelling.

AI Aces the Interview

RAD-TTS can manufacture a variety of voices, helping developers bring book characters to life or even rap tunes like “The Real Slim Shady” by Eminem, as the research group displayed in the demonstrations finale.

SIGGRAPH continues through Aug. 13. Take a look at the complete lineup of NVIDIA occasions at the conference and catch the premiere of our documentary, “Connecting in the Metaverse: The Making of the GTC Keynote,” on Aug. 11.

” Making digital avatars is a notoriously difficult, pricey and tedious procedure,” stated Bryan Catanzaro, vice president of used deep learning research study at NVIDIA, in the discussion. With AI tools, “there is an easy way to develop digital avatars for real people as well as animation characters. Rather of sending a video stream, the researchers system sent just his voice– which was then fed into the NVIDIA Omniverse Audio2Face app. Audio2Face produces natural motion of the head, lips and eyes to match audio input in genuine time on a 3D head design. This facial animation went into Vid2Vid Cameo to synthesize natural-looking movement with the presenters digital avatar.

Not just for photorealistic digital avatars, the scientist fed his speech through Audio2Face and Vid2Vid Cameo to voice an animated character, too. Using NVIDIA StyleGAN, he explained, designers can produce limitless digital avatars modeled after animation characters or paintings.

Instead of transmitting a video stream, the scientists system sent out only his voice– which was then fed into the NVIDIA Omniverse Audio2Face app. Audio2Face creates natural motion of the head, lips and eyes to match audio input in genuine time on a 3D head model. This facial animation entered into Vid2Vid Cameo to manufacture natural-looking movement with the speakers digital avatar.

The scientist enacting interviewee relied on an NVIDIA RTX laptop throughout, while the other utilized a desktop workstation powered by RTX A6000 GPUs. The entire pipeline can also be worked on GPUs in the cloud.

Taking it a step even more, the researcher revealed that when his coffeehouse surroundings got too loud, the RAD-TTS design could convert typed messages into his voice– changing the audio fed into Audio2Face. The breakthrough text-to-speech, deep learning-based tool can manufacture lifelike speech from arbitrary text inputs in milliseconds.

The models, enhanced to work on NVIDIA RTX GPUs, quickly deliver video at 30 frames per second. Its also extremely bandwidth efficient, given that the speaker is sending just audio data over the network rather of transferring a high-resolution video feed.

While sitting in a campus coffee shop, wearing a baseball cap and a face mask, the interviewee utilized the Vid2Vid Cameo model to appear clean-shaven in a collared shirt on the video call (seen in the image above). The AI model produces practical digital avatars from a single picture of the topic– no 3D scan or specialized training images needed.

“The digital avatar development is instant, so I can quickly develop a different avatar by utilizing a various picture,” he said, demonstrating the ability with another 2 images of himself.

In the demonstration, two NVIDIA research scientists enacted a recruiter and a potential hire speaking over video conference. Over the course of the call, the interviewee displayed the capabilities of AI-driven digital avatar technology to communicate with the job interviewer.
