Recovery of Graph Signals from Sign Measurements
Wenwei Liu, Hui Feng, Kaixuan Wang +2
Sampling and interpolation have been extensively studied, in order to reconstruct or estimate the entire graph signal from the signal values on a subset of vertexes, of which most…
Regularized Recovery by Multi-order Partial Hypergraph Total Variation
Ruyuan Qu, Jiaqi He, Hui Feng +2
Capturing complex high-order interactions among data is an important task in many scenarios. A common way to model high-order interactions is to use hypergraphs whose topology can…
Performance Analysis for Correlated AoI and Energy Efficiency in Heterogeneous CR-IoT System
Xiaoyu Hao, Tao Yang, Yulin Hu +1
We consider a cognitive radio based Internet of Things (CR-IoT) system where the secondary IoT device (SD) accesses the licensed channel during the transmission vacancies of the pr…
Two-Timescale Resource Allocation for Cooperative D2D Communication: A Matching Game Approach
Yiling Yuan, Tao Yang, Yulin Hu +2
In this paper, we consider a cooperative device-todevice (D2D) communication system, where the D2D transmitters (DTs) act as relays to assist the densified cellular network users (…
Sampling Policy Design for Tracking Time-Varying Graph Signals with Adaptive Budget Allocation
Xuan Xie, Hui Feng, Bo Hu
There have been many works that focus on the sampling set design for a static graph signal, but few for time-varying graph signals (GS). In this paper, we concentrate on how to sel…
Fast Color-guided Depth Denoising for RGB-D Images by Graph Filtering
Qiwei Huang, Ruikang Li, Zidong Jiang +4
Depth images captured by off-the-shelf RGB-D cameras suffer from much stronger noise than color images. In this paper, we propose a method to denoise the depth images in RGB-D imag…
