STCMOT: Spatio-Temporal Cohesion Learning for UAV-Based Multiple Object Tracking

Autor: Ma, Jianbo, Tang, Chuanming, Wu, Fei, Zhao, Can, Zhang, Jianlin, Xu, Zhiyong

Multiple object tracking (MOT) in Unmanned Aerial Vehicle (UAV) videos is important for diverse applications in computer vision. Current MOT trackers rely on accurate object detection results and precise matching of target reidentification (ReID). Th

Performance Analysis of Photon-Limited Free-Space Optical Communications with Practical Photon-Counting Receivers

Autor: Wang, Chen, Xu, Zhiyong, Wang, Jingyuan, Li, Jianhua, Mou, Weifeng, Zhu, Huatao, Zhao, Jiyong, Su, Yang, Wang, Yimin, Qi, Ailin

The non-perfect factors of practical photon-counting receiver are recognized as a significant challenge for long-distance photon-limited free-space optical (FSO) communication systems. This paper presents a comprehensive analytical framework for mode

A Novel Signal Detection Method for Photon-Counting Communications with Nonlinear Distortion Effects

Autor: Wang, Chen, Xu, Zhiyong, Wang, Jingyuan, Li, Jianhua, Mou, Weifeng, Zhu, Huatao, Zhao, Jiyong, Su, Yang, Wang, Yimin, Qi, Ailin

This paper proposes a method for estimating and detecting optical signals in practical photon-counting receivers. There are two important aspects of non-perfect photon-counting receivers, namely, (i) dead time which results in blocking loss, and (ii)

RSTAR4D: Rotational Streak Artifact Reduction in 4D CBCT using a Separable 4D CNN

Autor: Deng, Ziheng, Chen, Hua, Zhou, Yongzheng, Hu, Haibo, Xu, Zhiyong, Sun, Jiayuan, Lyu, Tianling, Xi, Yan, Chen, Yang, Zhao, Jun

Four-dimensional cone-beam computed tomography (4D CBCT) provides respiration-resolved images and can be used for image-guided radiation therapy. However, the ability to reveal respiratory motion comes at the cost of image artifacts. As raw projectio
