Geometrized Transformer for Self-Supervised Homography Estimation

1 code implementation ICCV 2023 Jiazhen Liu, Xirong Li

Such a homography allows us to compute cross-attention in a focused manner, where key/value sets required by Transformers can be reduced to small fix-sized regions rather than an entire image.

Attention-aware Resource Allocation and QoE Analysis for Metaverse xURLLC Services

2 code implementations10 Aug 2022 Hongyang Du, Jiazhen Liu, Dusit Niyato, Jiawen Kang, Zehui Xiong, Junshan Zhang, Dong In Kim

Although conventional ultra-reliable and low-latency communications (URLLC) can satisfy objective KPIs, it is difficult to provide a personalized immersive experience that is a distinctive feature of the Metaverse.

Semi-Supervised Keypoint Detector and Descriptor for Retinal Image Matching

1 code implementation16 Jul 2022 Jiazhen Liu, Xirong Li, Qijie Wei, Jie Xu, Dayong Ding

To attack the incompleteness of manual labeling, we propose Progressive Keypoint Expansion to enrich the keypoint labels at each training epoch.

FV-UPatches: Enhancing Universality in Finger Vein Recognition

1 code implementation2 Jun 2022 Ziyan Chen, Jiazhen Liu, Changwen Cao, Changlong Jin, Hakil Kim

In the proposed framework, the domain mapper is an approximation to a specific extraction function thus the training is only a one-time effort with limited data.
