ALIKE: Accurate and Lightweight Keypoint Detection and Descriptor Extraction

1 code implementation6 Dec 2021 Xiaoming Zhao, Xingming Wu, Jinyu Miao, Weihai Chen, Peter C. Y. Chen, Zhengguo Li

The reprojection loss is then proposed to directly optimize these sub-pixel keypoints, and the dispersity peak loss is presented for accurate keypoints regularization.

Discriminative and Semantic Feature Selection for Place Recognition towards Dynamic Environments

no code implementations18 Mar 2021 Yuxin Tian, Jinyu Miao, Xingming Wu, Haosong Yue, Zhong Liu, Weihai Chen

In this paper, we address the challenges of place recognition due to dynamics and confusable patterns by proposing a discriminative and semantic feature selection network, dubbed as DSFeat.
