A Noise Filter for Dynamic Vision Sensors using Self-adjusting Threshold

Autor: Guo, Shasha, Kang, Ziyang, Wang, Lei, Zhang, Limeng, Chen, Xiaofan, Li, Shiming, Xu, Weixia

Neuromorphic event-based dynamic vision sensors (DVS) have much faster sampling rates and a higher dynamic range than frame-based imagers. However, they are sensitive to background activity (BA) events which are unwanted. we propose a new criterion w

Self-adjusting threshold mechanism for pixel detectors

Autor: Timon Heim, Maurice Garcia-Sciveres

Publikováno v: Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment. 867:209-214

Readout chips of hybrid pixel detectors use a low power amplifier and threshold discrimination to process charge deposited in semiconductor sensors. Due to transistor mismatch each pixel circuit needs to be calibrated individually to achieve response

A general analysis of self-adjustment algorithm of fire detectors for early guaranteed ignition detection was carried out. It was shown that step magnitude in the algorithm of self-adjustment of fire detectors can be a fixed or a selected variable, d
