Unsupervised Visual Odometry and Action Integration for PointGoal Navigation in Indoor Environment

no code implementations2 Oct 2022 Yijun Cao, Xianshi Zhang, Fuya Luo, Chuan Lin, YongJie Li

To improve the PointGoal navigation accuracy without GPS signal, we use visual odometry (VO) and propose a novel action integration module (AIM) trained in unsupervised manner.

Learning Generalized Visual Odometry Using Position-Aware Optical Flow and Geometric Bundle Adjustment

no code implementations22 Nov 2021 Yijun Cao, Xianshi Zhang, Fuya Luo, Peng Peng, YongJie Li

The experiments show that the proposed system not only achieves comparable performance with other state-of-the-art self-supervised learning-based methods on the KITTI dataset, but also significantly improves the generalization capability compared with geometry-based, learning-based and hybrid VO systems on the noisy KITTI and the challenging outdoor (KAIST) scenes.

TSN-CA: A Two-Stage Network with Channel Attention for Low-Light Image Enhancement

no code implementations6 Oct 2021 Xinxu Wei, Xianshi Zhang, Shisen Wang, Yanlin Huang, YongJie Li

In this paper, we propose a Two-Stage Network with Channel Attention (denoted as TSN-CA) to enhance the brightness of the low-light image and restore the enhanced images from various kinds of degradation.

DA-DRN: Degradation-Aware Deep Retinex Network for Low-Light Image Enhancement

no code implementations5 Oct 2021 Xinxu Wei, Xianshi Zhang, Shisen Wang, Cheng Cheng, Yanlin Huang, KaiFu Yang, YongJie Li

We propose a Degradation-Aware Module (DA Module) which can guide the training process of the decomposer and enable the decomposer to be a restorer during the training phase without additional computational cost in the test phase.
