Microsoft’s AI app VASA-1 makes Photographs Talk and Sing with believable Facial Expressions

Microsoft's AI app VASA-1 makes photographs talk and sing with believable facial expressions
Given a single portrait image, a speech audio clip, and optionally a set of other control signals, our approach produces a high-quality lifelike talking face video of 512× 512 resolution at up to 40 FPS. The method is generic and robust, and the generated talking faces can faithfully mimic human facial expressions and head movements, reaching a high level of realism and liveliness. (All the photorealistic portrait images in this paper are virtual, non-existing identities.). Credit: arXiv (2024). DOI: 10.48550/arxiv.2404.10667

A team of AI researchers at Microsoft Research Asia has developed an AI application that converts a still image of a person and an audio track into an animation that accurately portrays the individual speaking or singing the audio track with appropriate facial ...

A team led by researchers from the University of Glasgow has developed an innovative wireless communications antenna that combines the unique properties of metamaterials with sophisticated signal processing to deliver a new peak of performance.

In a paper published in the IEEE Open Journal of Antennas and Propagation, titled “60 GHz Programmable Dynamic Metasurface Antenna (DMA) for Next-Generation Communication, Sensing, and Imaging Applications: From Concept to Prototype,” the researchers showcase their development of a prototype digitally coded dynamic metasurface antenna, or DMA, controlled through high-speed field-programmable gate array (FPGA).

Their DMA is the first in the world designed and demonstrated at the operating frequ...
