Sharp inequality for $\ell_p$ quasi-norm and $\ell_q$-norm with $0<p\leq 1$ and $q>1$

no code implementations27 Dec 2023 Zenghui Zhang

A sharp inequality for $\ell_p$ quasi-norm with $0<p\leq 1$ and $\ell_q$-norm with $q>1$ is derived, which shows that the difference between $\|\textbf{\textit{x}}\|_p$ and $\|\textbf{\textit{x}}\|_q$ of an $n$-dimensional signal $\textbf{\textit{x}}$ is upper bounded by the difference between the maximum and minimum absolute value in $\textbf{\textit{x}}$.

Interference-Resilient OFDM Waveform Design with Subcarrier Interval Constraint for ISAC Systems

no code implementations26 Dec 2023 Qinghui Lu, Zhen Du, Zenghui Zhang

Conventional orthogonal frequency division multiplexing (OFDM) waveform design in integrated sensing and communications (ISAC) systems usually selects the channels with high-frequency responses to transmit communication data, which does not fully consider the possible interference in the environment.

Towards ISAC-Empowered Vehicular Networks: Framework, Advances, and Opportunities

no code implementations1 May 2023 Zhen Du, Fan Liu, Yunxin Li, Weijie Yuan, Yuanhao Cui, Zenghui Zhang, Christos Masouros, Bo Ai

Connected and autonomous vehicle (CAV) networks face several challenges, such as low throughput, high latency, and poor localization accuracy.

Spatio-Temporal Point Process for Multiple Object Tracking

no code implementations5 Feb 2023 Tao Wang, Kean Chen, Weiyao Lin, John See, Zenghui Zhang, Qian Xu, Xia Jia

As such, we propose a novel framework that can effectively predict and mask-out the noisy and confusing detection results before associating the objects into trajectories.

Name Your Colour For the Task: Artificially Discover Colour Naming via Colour Quantisation Transformer

1 code implementation ICCV 2023 Shenghan Su, Lin Gu, Yue Yang, Zenghui Zhang, Tatsuya Harada

Besides, our colour quantisation method also offers an efficient quantisation method that effectively compresses the image storage while maintaining high performance in high-level recognition tasks such as classification and detection.

Exploring Resolution and Degradation Clues as Self-supervised Signal for Low Quality Object Detection

1 code implementation5 Aug 2022 Ziteng Cui, Yingying Zhu, Lin Gu, Guo-Jun Qi, Xiaoxiao Li, Renrui Zhang, Zenghui Zhang, Tatsuya Harada

Image restoration algorithms such as super resolution (SR) are indispensable pre-processing modules for object detection in low quality images.

Multitask AET with Orthogonal Tangent Regularity for Dark Object Detection

2 code implementations ICCV 2021 Ziteng Cui, Guo-Jun Qi, Lin Gu, ShaoDi You, Zenghui Zhang, Tatsuya Harada

To enhance object detection in a dark environment, we propose a novel multitask auto encoding transformation (MAET) model which is able to explore the intrinsic pattern behind illumination translation.
