Exploring Adversarial Learning for Deep Semi-Supervised Facial Action Unit Recognition

no code implementations4 Jun 2021 Shangfei Wang, Yanan Chang, Guozhu Peng, Bowen Pan

Specifically, the proposed deep semi-supervised AU recognition approach consists of a deep recognition network and a discriminator D. The deep recognition network R learns facial representations from large-scale facial images and AU classifiers from limited ground truth AU labels.

VA-RED$^2$: Video Adaptive Redundancy Reduction

no code implementations ICLR 2021 Bowen Pan, Rameswar Panda, Camilo Fosco, Chung-Ching Lin, Alex Andonian, Yue Meng, Kate Saenko, Aude Oliva, Rogerio Feris

An inherent property of real-world videos is the high correlation of information across frames which can translate into redundancy in either temporal or spatial feature maps of the models, or both.

Cross-view Semantic Segmentation for Sensing Surroundings

1 code implementation9 Jun 2019 Bowen Pan, Jiankai Sun, Ho Yin Tiga Leung, Alex Andonian, Bolei Zhou

Our further experiment on a LoCoBot robot shows that our model enables the surrounding sensing capability from 2D image input.
