Integrated sensing and communication (ISAC) has evolved as a critical paradigm to enhance the dual functions concurrently. However, ISAC may encounter performance limitations, due to undesired channel conditions, small target size, and security threats. In this paper, we investigate intelligent reconfigurable surface (IRS)-aided bi-static ISAC networks, where the IRS is mounted directly on the tar...Show More
Integrated sensing and communication (ISAC) has developed into a critical paradigm to enable beyond communication capabilities while enhancing the dual functions concurrently. However, ISAC may encounter performance limitations, due to unfavorable channel conditions and limited target size. In this paper, we investigate the intelligent reconfigurable surface (IRS)-aided bi-static ISAC networks, wh...Show More
Copper cables have limited the propagation distance of PCIe signal due to data rate increasing. In this paper, we demonstrated a linear drive optical solution for PCIe Gen5 and developed a PCIe AIC (Add in Card) integrating a PCIe switch and QSFP (Quad Small Form-factor Pluggable) linear drive optics. A 30 meters Gen5 optical link was connected between two optical cards. Then signal quality and ap...Show More
Visible (VIS) and infrared image registration is a challenging problem in computer vision due to the significant differences in appearance and physical properties between the two modalities. A single feature is not enough to remove nonlinear differences, and the matching method faces a trade-off between the high-resolution feature map and the transformer model. In this article, we propose a novel ...Show More
This article investigates the camera calibration problem in the field of computer vision, which is a key technology connecting 2-D vision with 3-D world and directly affecting the accuracy of computer vision systems. In this article, a camera calibration method is proposed by combining a laser projection turntable. The proposed method includes the following main contributions. First, a homemade la...Show More
Imaging photoplethysmography (IPPG) enables contactless physiological parameters monitoring using a regular video camera, which led to an increasing interest in video health monitoring. However, classical IPPG is unable to accurately measure heart rate over a long-distance motion. In this paper, an IPPG heart rate detection framework is proposed based on an adaptive-zoom system called adaptive-zoo...Show More
Wavefront coding (WFC) is a prosperous technology for extending depth of field (DOF) in the incoherent imaging system. Digital recovery of the WFC technique is a classical ill-conditioned problem by removing the blurring effect and suppressing the noise. Traditional approaches relying on image heuristics suffer from high frequency noise amplification and processing artifacts. This paper investigat...Show More
In this paper, we compare the performance of radar and optical (camera based) techniques in detecting vital signs such as respiratory rate (RR), heart rate (HR), and blood oxygen saturation (SpO2). Specifically, we investigate the application of ultrawideband stepped-frequency continuous-wave radar and imaging photoplethysmography (iPPG) techniques to measure vital signs. The radar performance can...Show More
