360SFUDA++: Towards Source-free UDA for Panoramic Segmentation by Learning Reliable Category Prototypes

no code implementations25 Apr 2024 Xu Zheng, Pengyuan Zhou, Athanasios V. Vasilakos, Lin Wang

However, as the distinct projections make it less possible to directly transfer knowledge between domains, we then propose Reliable Panoramic Prototype Adaptation Module (RP2AM) to transfer knowledge at both prediction and prototype levels.

Unsupervised Visible-Infrared ReID via Pseudo-label Correction and Modality-level Alignment

no code implementations10 Apr 2024 Yexin Liu, Weiming Zhang, Athanasios V. Vasilakos, Lin Wang

Specifically, to address the first challenge, we propose a pseudo-label correction strategy that utilizes a Beta Mixture Model to predict the probability of mis-clustering based network's memory effect and rectifies the correspondence by adding a perceptual term to contrastive learning.

Semantics, Distortion, and Style Matter: Towards Source-free UDA for Panoramic Segmentation

no code implementations19 Mar 2024 Xu Zheng, Pengyuan Zhou, Athanasios V. Vasilakos, Lin Wang

However, the distinct projection discrepancies between source and target domains impede the direct knowledge transfer; thus, we propose a panoramic prototype adaptation module (PPAM) to integrate panoramic prototypes from the extracted knowledge for adaptation.
