In the progress of constructing an intelligent future, datasets play a vital role. From autonomous driving cars to smart security systems, high-quality datasets provide AI models with massive amount of learning materiel, empowering AI model more adaptable in various real-world scenarios. Companies and researchers through continuously improving the efficiency of data collection and annotation can accelerate the implementation of AI technology, help all industries achieve their digital transformation.

Recently, the paper Face2Faceρ: Real-Time High-Resolution One-Shot Face Reenactment, co-authored by Netease AI Lab and Tsinghua University, was selected for ECCV 2022, the top international conference on computer vision. This paper innovatively proposes a new method of face reenactment, which can increase the algorithm speed up to 9 times while ensuring the quality of the image generation.

Face reenactment algorithm is a kind of algorithm that takes the source face image as input, and transfer the facial expressions and head poses that drive the face into the source image, while ensuring that the identity of the source face remains unchanged during the migration process.

In recent years, Face Reenactment technology has attracted much attention due to its application prospects in media, entertainment, virtual reality, etc. Its most direct help is to improve the production efficiency of audio and video. In the field of video cloud, low latency and high image quality of video transmission have always been two points that are difficult to balance. At present, the minimum delay of live broadcast can be reduced to less than 400ms, but in the case of increasing demand for video conferences and other scenarios, such as remote PPT presentations, which have higher requirements for the balance between image quality and delay. The combination of face reenactment algorithm and codec technology will greatly reduce bandwidth requirements in the application of video conference scenarios, thereby realizing ultra-low latency and high-quality video conferences.

As we all know, data is as important to the AI industry as oil is to industry. The improvement of the face reenactment algorithm is inseparable from the support of training data. Nexdata owns an impressive amount of face datasets, covering multiple scenes, multiple races, and multiple poses.
