T-SEA: Transfer-based Self-Ensemble Attack on Object Detection

1 code implementation CVPR 2023 Hao Huang, Ziyan Chen, Huanran Chen, Yongtao Wang, Kevin Zhang

Then, we analogize patch optimization with regular model optimization, proposing a series of self-ensemble approaches on the input data, the attacked model, and the adversarial patch to efficiently make use of the limited information and prevent the patch from overfitting.

Hyperspectral image reconstruction for spectral camera based on ghost imaging via sparsity constraints using V-DUnet

no code implementations28 Jun 2022 Ziyan Chen, Zhentao Liu, Chenyu Hu, Heng Wu, Jianrong Wu, Jinda Lin, Zhishen Tong, Hong Yu, Shensheng Han

When applying deep learning into GISC spectral camera, there are several challenges need to be solved: 1) how to deal with the large amount of 3D hyperspectral data, 2) how to reduce the influence caused by the uncertainty of the random reference measurements, 3) how to improve the reconstructed image quality as far as possible.

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.
