Learning Meta Pattern for Face Anti-Spoofing

1 code implementation13 Oct 2021 Rizhao Cai, Zhi Li, Renjie Wan, Haoliang Li, Yongjian Hu, Alex ChiChung Kot

To improve the generalization ability, recent hybrid methods have been explored to extract task-aware handcrafted features (e. g., Local Binary Pattern) as discriminative information for the input of DNNs.

DRL-FAS: A Novel Framework Based on Deep Reinforcement Learning for Face Anti-Spoofing

no code implementations16 Sep 2020 Rizhao Cai, Haoliang Li, Shiqi Wang, Changsheng chen, Alex ChiChung Kot

Inspired by the philosophy employed by human beings to determine whether a presented face example is genuine or not, i. e., to glance at the example globally first and then carefully observe the local regions to gain more discriminative information, for the face anti-spoofing problem, we propose a novel framework based on the Convolutional Neural Network (CNN) and the Recurrent Neural Network (RNN).

Multi-task Mid-level Feature Alignment Network for Unsupervised Cross-Dataset Person Re-Identification

no code implementations4 Jul 2018 Shan Lin, Haoliang Li, Chang-Tsun Li, Alex ChiChung Kot

Most existing person re-identification (Re-ID) approaches follow a supervised learning framework, in which a large number of labelled matching pairs are required for training.
