EDMOT: A 25–65 ns Latency Event-Driven Multiobject Tracker for Dynamic Vision Sensors

Yujie Huang, Y. B. Chen, Mingyu Wang, Minge Jing et autres

Dynamic vision sensors (DVSs), renowned for their low latency and sparse event-driven output, have garnered significant attention in machine vision applications, particularly in latency-sensitive applications like object tracking. However, current DVS-based object tracking systems have not fully utilized the advantages of DVS …

0377 Associations of Evening-type and Insomnia Symptoms with Depressive Symptoms Among Adolescents and Young Adults

Jianyu Que, Sijing Chen, Ngan Yin Chan, Suying Wu et autres

Abstract Introduction Evening-type and insomnia symptoms are closely related to each other and independently associated with depressive symptoms, yet few studies have examined the potential interaction between these two conditions. Therefore, we aimed to examine the associations of evening-type and insomnia symptoms …

IMA-BLC: Iterative Median-Averaged Adaptive Black-Level Correction Method

Y. B. Chen, Yujie Huang, Mingyu Wang, Wenhong Li et autres

To accommodate temperature changes, typical black level correction methods utilize black pixels to obtain the black level value instead of using a fixed corrected value. However, this type of method is susceptible to bad pixels. Although some sorting-based algorithms can correct these …

Queue-based Spatiotemporal Filter and Clustering for Dynamic Vision Sensor

Feiqiang Li, Yujie Huang, Y. B. Chen, Xiaoyang Zeng et autres

Dynamic vision sensors (DVS) have significant potential in scenes involving high-speed motion and extreme light. However, DVS is sensitive to background active noise, which will degrade the quality of the output. The ordinary$O(N^{2})$-Space spatiotemporal filter's memory complexity is high. It needs$N\times N$memory …

Denoising Method for Dynamic Vision Sensor Based on Two-Dimensional Event Density

Y. B. Chen, Yujie Huang, Feiqiang Li, Xiaoyang Zeng et autres

The Dynamic Vision Sensor (DVS) is a new type of bionic vision image sensor that offers the advantages of low latency, low power consumption, and high dynamics range compared to conventional sensors. However, background activity (BA) noise will degrade the quality of …

Peculiar Disk Behaviors of the Black Hole Candidate MAXI J1348–630 in the Hard State Observed by Insight-HXMT and Swift

W. Zhang, Lian Tao, Roberto Soria, Jin‐Lu Qu et autres

Abstract We present a spectral study of the black hole candidate MAXI J1348−630 during its 2019 outburst, based on monitoring observations with Insight-HXMT and Swift. Throughout the outburst, the spectra are well fitted with power-law plus disk-blackbody components. In the soft-intermediate and …

Accretion Torque Reversals in GRO J1008-57 Revealed by Insight-HXMT

Wei Wang, Y. M. Tang, Y. L. Tuo, Prahlad R. Epili et autres

GRO J1008-57, as a Be/X-ray transient pulsar, is considered to have the highest magnetic field in known neutron star X-ray binary systems. Observational data of the X-ray outbursts in GRO J1008-57 from 2017 to 2020 were collected by the Insight-HXMT satellite. In …

Two Complete Spectral Transitions of Swift J0243.6+6124 Observed by Insight-HXMT

Ling-Da Kong, Shuo Zhang, Yupeng Chen, Shuang‐Nan Zhang et autres

Abstract We performed the broadband (1–100 keV) spectral analysis of the first Galactic Be ultraluminous X-ray pulsar (BeULX) Swift J0243.6+6124 observed by Insight-HXMT during the 2017−2018 outburst. The results show spectral transitions at two typical luminosities, roughly consistently with those reported previously …

Insight-HXMT Firm Detection of the Highest-energy Fundamental Cyclotron Resonance Scattering Feature in the Spectrum of GRO J1008-57

Mingyu Ge, Long Ji, Shuang‐Nan Zhang, Andrea E. Santangelo et autres

Abstract We report on the observation of the accreting pulsar GRO J1008-57 performed by Insight-Hard X-ray Modulation Telescope (HXMT) at the peak of the source’s 2017 outburst. Pulsations are detected with a spin period of 93.283(1) s. The pulse profile shows double …

Discovery of Delayed Spin-up Behavior Following Two Large Glitches in the Crab Pulsar, and the Statistics of Such Processes

Mingyu Ge, Shuang‐Nan Zhang, F. J. Lu, Tong Li et autres

Abstract Glitches correspond to sudden jumps of rotation frequency (ν) and its derivative ( ) of pulsars, the origin of which remains not well understood yet, partly because the jump processes of most glitches are not well time-resolved. There are three large …

Constant cyclotron line energy in Hercules X-1 -- Joint Insight-HXMT and NuSTAR observations

Guang-Cheng Xiao, Long Ji, Rüdiger Staubert, M. Y. Ge et autres

The long-term evolution of the centroid energy of the CRSF in Her X-1 is still a mystery. We report a new measurement from a campaign between {\sl Insight}-HXMT and {\sl NuSTAR} performed in February 2018. Generally, the two satellites show well consistent …
