Xiongjun Guan

I am a third year Ph.D student in i-VisionGroup in the Department of Automation at Tsinghua University, advised by Prof. Jianjiang Feng .
In 2021, I received my B.S. degree from the Department of Automation and a minor from Academy of Arts and Design , Tsinghua University.

I have a broad interest in computer vision and pattern recognition. At present, my research mainly focus on fingerprint recoginition.

A novel framework for joint partial fingerprint identity verification and pose alignment of partial fingerprint pairs is proposed, which utilizes a multi-task CNN-Transformer hybrid network and a pre-training task on enhancement.

Latent fingerprint matching is a daunting task, primarily due to the poor quality of latent fingerprints. In this study, we propose a deep-learning based dense minutia descriptor (DMD) for latent fingerprint matching.

We propose a Phase-aggregated Dual-branch Registration Network to combine the strengths of traditional fingerprint dense registration methods and deep learning.

We proposed an end-to-end network to directly estimate a dense distortion field instead of its low dimensional representation, from a single fingerprint.

We proposed an end-to-end network to directly estimate a dense distortion field from a single fingerprint instead of its low dimensional representation.

We proposed a visualization and pose-specific unfolding method for 3D fingerprints, which can improve the compatibility between 3D and 2D fingerprints in recognition.
