View-Centric Multi-Object Tracking with Homographic Matching in Moving UAV

no code implementations16 Mar 2024 Deyi Ji, Siqi Gao, Lanyun Zhu, Yiru Zhao, Peng Xu, Hongtao Lu, Feng Zhao

In this paper, we address the challenge of multi-object tracking (MOT) in moving Unmanned Aerial Vehicle (UAV) scenarios, where irregular flight trajectories, such as hovering, turning left/right, and moving up/down, lead to significantly greater complexity compared to fixed-camera MOT.

Guided Patch-Grouping Wavelet Transformer with Spatial Congruence for Ultra-High Resolution Segmentation

no code implementations3 Jul 2023 Deyi Ji, Feng Zhao, Hongtao Lu

For the sake of high inference speed and low computation complexity, $\mathcal{T}$ partitions the original UHR image into patches and groups them dynamically, then learns the low-level local details with the lightweight multi-head Wavelet Transformer (WFormer) network.

Ultra-High Resolution Segmentation with Ultra-Rich Context: A Novel Benchmark

1 code implementation CVPR 2023 Deyi Ji, Feng Zhao, Hongtao Lu, Mingyuan Tao, Jieping Ye

With the increasing interest and rapid development of methods for Ultra-High Resolution (UHR) segmentation, a large-scale benchmark covering a wide range of scenes with full fine-grained dense annotations is urgently needed to facilitate the field.

Class-wise Dynamic Graph Convolution for Semantic Segmentation

no code implementations ECCV 2020 Hanzhe Hu, Deyi Ji, Weihao Gan, Shuai Bai, Wei Wu, Junjie Yan

Specifically, the CDGC module takes the coarse segmentation result as class mask to extract node features for graph construction and performs dynamic graph convolutions on the constructed graph to learn the feature aggregation and weight allocation.
