Spatiotemporal Learning of Multivehicle Interaction Patterns in Lane-Change Scenarios

1 code implementation2 Mar 2020 Chengyuan Zhang, Jiacheng Zhu, Wenshuo Wang, Junqiang Xi

Results demonstrate that our proposed Bayesian nonparametric approach provides an insight into the complicated lane-change interactions of the ego vehicle with multiple surrounding traffic participants based on the interpretable interaction patterns and their transition properties in temporal relationships.

PAC-GAN: An Effective Pose Augmentation Scheme for Unsupervised Cross-View Person Re-identification

no code implementations5 Jun 2019 Chengyuan Zhang, Lei Zhu, Shichao Zhang

In this paper, we introduce a novel unsupervised pose augmentation cross-view person Re-Id scheme called PAC-GAN to overcome these limitations.

Crossing Generative Adversarial Networks for Cross-View Person Re-identification

no code implementations4 Jan 2018 Chengyuan Zhang, Lin Wu, Yang Wang

Given a pair of person images, the proposed model consists of the variational auto-encoder to encode the pair into respective latent variables, a proposed cross-view alignment to reduce the view disparity, and an adversarial layer to seek the joint distribution of latent representations.
