AFNet-M: Adaptive Fusion Network with Masks for 2D+3D Facial Expression Recognition

no code implementations24 May 2022 Mingzhe Sui, Hanting Li, Zhaoqing Zhu, Feng Zhao

2D+3D facial expression recognition (FER) can effectively cope with illumination changes and pose variations by simultaneously merging 2D texture and more robust 3D depth information.

Towards 3D Scene Reconstruction from Locally Scale-Aligned Monocular Video Depth

1 code implementation3 Feb 2022 Guangkai Xu, Wei Yin, Hao Chen, Kai Cheng, Feng Zhao, Chunhua Shen

However, in some video-based scenarios such as video depth estimation and 3D scene reconstruction from a video, the unknown scale and shift residing in per-frame prediction may cause the depth inconsistency.

Unleashing the Potential of Unsupervised Pre-Training with Intra-Identity Regularization for Person Re-Identification

1 code implementation1 Dec 2021 Zizheng Yang, Xin Jin, Kecheng Zheng, Feng Zhao

During the pre-training, we attempt to address two critical issues for learning fine-grained ReID features: (1) the augmentations in CL pipeline may distort the discriminative clues in person images.
