Memorizing Comprehensively to Learn Adaptively: Unsupervised Cross-Domain Person Re-ID with Multi-level Memory

no code implementations13 Jan 2020 Xin-Yu Zhang, Dong Gong, Jiewei Cao, Chunhua Shen

Due to the lack of supervision in the target domain, it is crucial to identify the underlying similarity-and-dissimilarity relationships among the unlabelled samples in the target domain.

End-to-End Learnable Geometric Vision by Backpropagating PnP Optimization

2 code implementations CVPR 2020 Bo Chen, Alvaro Parra, Jiewei Cao, Nan Li, Tat-Jun Chin

To seamlessly combine deep learning and geometric vision, it is vital to perform learning and geometric optimization end-to-end.

Satellite Pose Estimation with Deep Landmark Regression and Nonlinear Pose Refinement

1 code implementation30 Aug 2019 Bo Chen, Jiewei Cao, Alvaro Parra, Tat-Jun Chin

We propose an approach to estimate the 6DOF pose of a satellite, relative to a canonical pose, from a single image.

V-PROM: A Benchmark for Visual Reasoning Using Visual Progressive Matrices

no code implementations29 Jul 2019 Damien Teney, Peng Wang, Jiewei Cao, Lingqiao Liu, Chunhua Shen, Anton Van Den Hengel

One of the primary challenges faced by deep learning is the degree to which current methods exploit superficial statistics and dataset bias, rather than learning to generalise over the specific representations they have experienced.

Neighbourhood Watch: Referring Expression Comprehension via Language-guided Graph Attention Networks

no code implementations CVPR 2019 Peng Wang, Qi Wu, Jiewei Cao, Chunhua Shen, Lianli Gao, Anton Van Den Hengel

Being composed of node attention component and edge attention component, the proposed graph attention mechanism explicitly represents inter-object relationships, and properties with a flexibility and power impossible with competing approaches.

Leveraging Weak Semantic Relevance for Complex Video Event Classification

no code implementations ICCV 2017 Chao Li, Jiewei Cao, Zi Huang, Lei Zhu, Heng Tao Shen

In this paper, we propose a novel approach to automatically maximize the utility of weak semantic annotations (formalized as the semantic relevance of video shots to the target event) to facilitate video event classification.

Where to Focus: Query Adaptive Matching for Instance Retrieval Using Convolutional Feature Maps

no code implementations22 Jun 2016 Jiewei Cao, Lingqiao Liu, Peng Wang, Zi Huang, Chunhua Shen, Heng Tao Shen

Instance retrieval requires one to search for images that contain a particular object within a large corpus.
