Exploiting Spatial-Temporal Context for Interacting Hand Reconstruction on Monocular RGB Video

no code implementations8 Aug 2023 Weichao Zhao, Hezhen Hu, Wengang Zhou, Li Li, Houqiang Li

Reconstructing interacting hands from monocular RGB data is a challenging task, as it involves many interfering factors, e. g. self- and mutual occlusion and similar textures.

DIRE for Diffusion-Generated Image Detection

1 code implementation ICCV 2023 Zhendong Wang, Jianmin Bao, Wengang Zhou, Weilun Wang, Hezhen Hu, Hong Chen, Houqiang Li

We find that existing detectors struggle to detect images generated by diffusion models, even if we include generated images from a specific diffusion model in their training data.

BEST: BERT Pre-Training for Sign Language Recognition with Coupling Tokenization

no code implementations10 Feb 2023 Weichao Zhao, Hezhen Hu, Wengang Zhou, Jiaxin Shi, Houqiang Li

In this work, we are dedicated to leveraging the BERT pre-training success and modeling the domain-specific statistics to fertilize the sign language recognition~(SLR) model.

Hand-Object Interaction Image Generation

no code implementations28 Nov 2022 Hezhen Hu, Weilun Wang, Wengang Zhou, Houqiang Li

In this work, we are dedicated to a new task, i. e., hand-object interaction image generation, which aims to conditionally generate the hand-object image under the given hand, object and their interaction status.

SignBERT: Pre-Training of Hand-Model-Aware Representation for Sign Language Recognition

no code implementations ICCV 2021 Hezhen Hu, Weichao Zhao, Wengang Zhou, Yuechen Wang, Houqiang Li

To validate the effectiveness of our method on SLR, we perform extensive experiments on four public benchmark datasets, i. e., NMFs-CSL, SLR500, MSASL and WLASL.

Boosting Continuous Sign Language Recognition via Cross Modality Augmentation

no code implementations11 Oct 2020 Junfu Pu, Wengang Zhou, Hezhen Hu, Houqiang Li

Continuous sign language recognition (SLR) deals with unaligned video-text pair and uses the word error rate (WER), i. e., edit distance, as the main evaluation metric.

Global-local Enhancement Network for NMFs-aware Sign Language Recognition

no code implementations24 Aug 2020 Hezhen Hu, Wengang Zhou, Junfu Pu, Houqiang Li

Sign language recognition (SLR) is a challenging problem, involving complex manual features, i. e., hand gestures, and fine-grained non-manual features (NMFs), i. e., facial expression, mouth shapes, etc.
