Self-Supervised Learning of Whole and Component-Based Semantic Representations for Person Re-Identification

Kavli Affiliate: Cheng Peng | First 5 Authors: Siyuan Huang, Yifan Zhou, Ram Prabhakar, Xijun Liu, Yuxiang Guo | Summary: Person Re-Identification (ReID) is a challenging problem, focusing on identifying individuals across diverse settings. However, previous ReID methods primarily concentrated on a single domain or modality, such as Clothes-Changing ReID (CC-ReID) and video ReID. Real-world […]

VILLS — Video-Image Learning to Learn Semantics for Person Re-Identification

Kavli Affiliate: Cheng Peng | First 5 Authors: Siyuan Huang, Ram Prabhakar, Yuxiang Guo, Rama Chellappa, Cheng Peng | Summary: Person Re-identification is a research area with significant real world applications. Despite recent progress, existing methods face challenges in robust re-identification in the wild, e.g., by focusing only on a particular modality and on unreliable […]

GaitContour: Efficient Gait Recognition based on a Contour-Pose Representation

Kavli Affiliate: Cheng Peng | First 5 Authors: Yuxiang Guo, Anshul Shah, Jiang Liu, Rama Chellappa, Cheng Peng | Summary: Gait recognition holds the promise to robustly identify subjects based on walking patterns instead of appearance information. In recent years, this field has been dominated by learning methods based on two principal input representations: dense […]

Low-Temperature Transport Property of Spin-1/2 Random Heisenberg Chains

Kavli Affiliate: Long Zhang | First 5 Authors: Yuejiu Zhao, Long Zhang, , , | Summary: Quenched disorders can strongly influence the physical properties of quantum many-body systems. The real-space strong-disorder renormalization group (SDRG) analysis has shown that the spin-1/2 random Heisenberg chain is controlled by the infinite-randomness fixed point (IRFP) and forms a random […]

Segmentation-Based Parametric Painting

Kavli Affiliate: Matthew Fisher | First 5 Authors: Manuel Ladron de Guevara, Matthew Fisher, Aaron Hertzmann, , | Summary: We introduce a novel image-to-painting method that facilitates the creation of large-scale, high-fidelity paintings with human-like quality and stylistic variation. To process large images and gain control over the painting process, we introduce a segmentation-based painting […]

Roles of Hund’s Rule and Hybridization in the Two-orbital Model for High-$T_c$ Superconductivity in the Bilayer Nickelate

Kavli Affiliate: Gang Su | First 5 Authors: Xing-Zhou Qu, Dai-Wei Qu, Wei Li, Gang Su, | Summary: The intriguing interplay between the two $e_g$ orbitals in the high-$T_c$ nickelate superconductor La$_3$Ni$_2$O$_7$ is studied via the density matrix renormalization group (DMRG) and finite-$T$ thermal tensor-network calculations. We consider a bilayer $t$-$J$ model that incorporates both […]

Transitive and non-transitive subgroups of permutation groups

Kavli Affiliate: Zheng Zhu | First 5 Authors: Arda Demirhan, Jacob Miller, Yixu Qiu, Thomas J. Tucker, Zheng Zhu | Summary: We treat the problem of finding transitive subgroups G of S_n containing normal subgroups N_1 and N_2, with N_1 transitive and N_2 not transitive, such that G/N_1 is isomorphic G/N_2. We show that such […]
