Global Spectral Filter Memory Network for Video Object Segmentation

1 code implementation11 Oct 2022 Yong liu, Ran Yu, Jiahao Wang, Xinyuan Zhao, Yitong Wang, Yansong Tang, Yujiu Yang

Besides, we empirically find low frequency feature should be enhanced in encoder (backbone) while high frequency for decoder (segmentation head).

WorldKG: A World-Scale Geographic Knowledge Graph

no code implementations21 Sep 2021 Alishiba Dsouza, Nicolas Tempelmeier, Ran Yu, Simon Gottschalk, Elena Demidova

We describe the WorldKG knowledge graph, including its ontology that builds the semantic dataset backbone, the extraction procedure of the ontology and geographic entities from OpenStreetMap, and the methods to enhance entity annotation.

Real-time Human-Centric Segmentation for Complex Video Scenes

1 code implementation16 Aug 2021 Ran Yu, Chenyu Tian, Weihao Xia, Xinyuan Zhao, Haoqian Wang, Yujiu Yang

To alleviate this problem, we propose a mechanism named Inner Center Sampling to improve the accuracy of instance segmentation.
