An End-to-End Cascaded Image Deraining and Object Detection Neural Network

no code implementations23 Feb 2022 Kaige Wang, Tianming Wang, Jianchuang Qu, Huatao Jiang, Qing Li, Lin Chang

Firstly, the gap between the low-level vision task represented by rain removal and the high-level vision task represented by object detection is significant, and the low-level vision task can hardly contribute to the high-level vision task.

Accelerated Structured Alternating Projections for Robust Spectrally Sparse Signal Recovery

2 code implementations13 Oct 2019 HanQin Cai, Jian-Feng Cai, Tianming Wang, Guojian Yin

We study the robust recovery problem for the spectrally sparse signal under the fully observed setting, which is about recovering $\boldsymbol{x}$ and a sparse corruption vector $\boldsymbol{s}$ from their sum $\boldsymbol{z}=\boldsymbol{x}+\boldsymbol{s}$.

DOB-Net: Actively Rejecting Unknown Excessive Time-Varying Disturbances

no code implementations10 Jul 2019 Tianming Wang, Wen-jie Lu, Zheng Yan, Dikai Liu

This paper presents an observer-integrated Reinforcement Learning (RL) approach, called Disturbance OBserver Network (DOB-Net), for robots operating in environments where disturbances are unknown and time-varying, and may frequently exceed robot control capabilities.

Blind Hyperspectral-Multispectral Image Fusion via Graph Laplacian Regularization

no code implementations21 Feb 2019 Chandrajit Bajaj, Tianming Wang

Fusing a low-resolution hyperspectral image (HSI) and a high-resolution multispectral image (MSI) of the same scene leads to a super-resolution image (SRI), which is information rich spatially and spectrally.
