Exploring Stronger Transformer Representation Learning for Occluded Person Re-Identification

no code implementations21 Oct 2024 Zhangjian Ji, Donglin Cheng, Kai Feng

Different from the general transformer-based person re-identification models, we designed a self-supervised contrastive learning branch, which can enhance the feature representation for person re-identification without negative samples or additional pre-training.

Degradation-Noise-Aware Deep Unfolding Transformer for Hyperspectral Image Denoising

no code implementations6 May 2023 Haijin Zeng, JieZhang Cao, Kai Feng, Shaoguang Huang, Hongyan zhang, Hiep Luong, Wilfried Philips

However, model-based approaches rely on hand-crafted priors and hyperparameters, while learning-based methods are incapable of estimating the inherent degradation patterns and noise distributions in the imaging procedure, which could inform supervised learning.
