SigFormer: Sparse Signal-Guided Transformer for Multi-Modal Human Action Segmentation

1 code implementation29 Nov 2023 Qi Liu, Xinchen Liu, Kun Liu, Xiaoyan Gu, Wu Liu

Nowadays, the majority of approaches concentrate on the fusion of dense signals (i. e., RGB, optical flow, and depth maps).

REMOT: A Region-to-Whole Framework for Realistic Human Motion Transfer

no code implementations1 Sep 2022 Quanwei Yang, Xinchen Liu, Wu Liu, Hongtao Xie, Xiaoyan Gu, Lingyun Yu, Yongdong Zhang

Human Video Motion Transfer (HVMT) aims to, given an image of a source person, generate his/her video that imitates the motion of the driving person.

Gait Recognition in the Wild with Multi-hop Temporal Switch

1 code implementation1 Sep 2022 Jinkai Zheng, Xinchen Liu, Xiaoyan Gu, Yaoqi Sun, Chuang Gan, Jiyong Zhang, Wu Liu, Chenggang Yan

Current methods that obtain state-of-the-art performance on in-the-lab benchmarks achieve much worse accuracy on the recently proposed in-the-wild datasets because these methods can hardly model the varied temporal dynamics of gait sequences in unconstrained scenes.

Delving into the Frequency: Temporally Consistent Human Motion Transfer in the Fourier Space

no code implementations1 Sep 2022 Guang Yang, Wu Liu, Xinchen Liu, Xiaoyan Gu, Juan Cao, Jintao Li

To close the frequency gap between the natural and synthetic videos, we propose a novel Frequency-based human MOtion TRansfer framework, named FreMOTR, which can effectively mitigate the spatial artifacts and the temporal inconsistency of the synthesized videos.

Revisiting Multi-Codebook Quantization

no code implementations NeurIPS 2021 Xiaosu Zhu, Jingkuan Song, Lianli Gao, Xiaoyan Gu, HengTao Shen

However, finding the optimal solution to MCQ is proved to be NP-hard due to its encoding process, \textit{i. e.}, converting an input vector to a binary code.
