About me

I will return to my alma mater, Fujian Normal University, for a faculty position.

I've received the Ph.D. degree from National Tsing Hua University in 2025, the master degree from National Central University in 2019, and the bachelor degree from Fujian Normal University in 2017. I live in Xiamen and Fuzhou, China.

My research area focuses on face anti-spoofing and rPPG Estimation. As the first author, I have been published in prestigious conferences in the field of computer vision, including CVPR, AAAI, BMVC, ICME, ICIP, and ACPR, as well as in renowned journals, including TIFS, Pattern Recognition, Information Science, and ATSIP.

I have reviewed papers from different CV/AI conferences, e.g., CVPR, ECCV, AAAI, ACM MM, and biomedical related journals, e.g., IJCV, TIFS, PR, TDSC, TIM.

Publishing papers is not easy. For the manuscripts I review, I strive to recommend acceptance with revisions whenever the quality of the work permits.

Enhancing Learnable Descriptive Convolutional Vision Transformer for Face Anti-Spoofing Pei-Kai Huang, Jun-Xiong Chong, Ming-Tsung Hsu, Fang-Yu Hsu, Chiou-Ting Hsu Pattern Recognition, 2026 [中科院一区Top, CCF B,TH-CPL Rank B, SCIE:Q1, IF:7.5, h-index:180] Paper | Code This paper was initially submitted in March 2024 and has undergone five rounds of revision involving eight reviewers. In each round, after we completed the revisions, some of the original reviewers were unfortunately unavailable to continue the review process, resulting in new reviewers being assigned and leading to repeated evaluation cycles. We are especially grateful to the Associate Editor assigned after the reject-and-resubmit decision for the constructive guidance and continuous support throughout the review process.
