Expressive Speech-driven Facial Animation with controllable emotions

1 code implementation5 Jan 2023 Yutong Chen, Junhong Zhao, Wei-Qiang Zhang

It is in high demand to generate facial animation with high realism, but it remains a challenging task.

Two-Stream Network for Sign Language Recognition and Translation

1 code implementation2 Nov 2022 Yutong Chen, Ronglai Zuo, Fangyun Wei, Yu Wu, Shujie Liu, Brian Mak

RGB videos, however, are raw signals with substantial visual redundancy, leading the encoder to overlook the key information for sign language understanding.

A Simple Multi-Modality Transfer Learning Baseline for Sign Language Translation

4 code implementations CVPR 2022 Yutong Chen, Fangyun Wei, Xiao Sun, Zhirong Wu, Stephen Lin

Concretely, we pretrain the sign-to-gloss visual network on the general domain of human actions and the within-domain of a sign-to-gloss dataset, and pretrain the gloss-to-text translation network on the general domain of a multilingual corpus and the within-domain of a gloss-to-text corpus.
