Multi-Centroid Representation Network for Domain Adaptive Person Re-ID

no code implementations22 Dec 2021 Yuhang Wu, Tengteng Huang, Haotian Yao, Chi Zhang, Yuanjie Shao, Chuchu Han, Changxin Gao, Nong Sang

First, we present a Domain-Specific Contrastive Learning (DSCL) mechanism to fully explore intradomain information by comparing samples only from the same domain.

Modality-Aware Triplet Hard Mining for Zero-shot Sketch-Based Image Retrieval

1 code implementation15 Dec 2021 Zongheng Huang, Yifan Sun, Chuchu Han, Changxin Gao, Nong Sang

By combining two fundamental learning approaches in DML, e. g., classification training and pairwise training, we set up a strong baseline for ZS-SBIR.

Decoupled and Memory-Reinforced Networks: Towards Effective Feature Learning for One-Step Person Search

no code implementations22 Feb 2021 Chuchu Han, Zhedong Zheng, Changxin Gao, Nong Sang, Yi Yang

Specifically, to reconcile the conflicts of multiple objectives, we simplify the standard tightly coupled pipelines and establish a deeply decoupled multi-task learning framework.

Deep Representation Learning on Long-tailed Data: A Learnable Embedding Augmentation Perspective

no code implementations CVPR 2020 Jialun Liu, Yifan Sun, Chuchu Han, Zhaopeng Dou, Wenhui Li

If a sample belongs to a tail class, the corresponding feature cloud will have relatively large distribution range, in compensation to its lack of diversity.

Re-ID Driven Localization Refinement for Person Search

no code implementations ICCV 2019 Chuchu Han, Jiacheng Ye, Yunshan Zhong, Xin Tan, Chi Zhang, Changxin Gao, Nong Sang

The state-of-the-art methods train the detector individually, and the detected bounding boxes may be sub-optimal for the following re-ID task.
