Lifetime estimation of events from Dynamic Vision Sensors [PDF]

open access: yes2015 IEEE International Conference on Robotics and Automation (ICRA), 2015
We propose an algorithm to estimate the “lifetime” of events from retinal cameras, such as a Dynamic Vision Sensor (DVS). Unlike standard CMOS cameras, a DVS only transmits pixel-level brightness changes (“events”) at the time they occur with micro-second resolution.

A High-Speed Vision-Based Sensor for Dynamic Vibration Analysis Using Fast Motion Extraction Algorithms

open access: yesSensors, 2016
The development of image sensor and optics enables the application of vision-based techniques to the non-contact dynamic vibration analysis of large-scale structures. As an emerging technology, a vision-based approach allows for remote measuring and does

Illumination-Based Synchronization of High-Speed Vision Sensors

open access: yesSensors, 2010
To acquire images of dynamic scenes from multiple points of view simultaneously, the acquisition time of vision sensors should be synchronized. This paper describes an illumination-based synchronization method derived from the phase-locked loop (PLL ...

In-vivo imaging of neural activity with dynamic vision sensors [PDF]

open access: yes2017 IEEE Biomedical Circuits and Systems Conference (BioCAS), 2017
Optical recording of neural activity using calcium or voltage indicators requires cameras capable of detecting small temporal contrast in light intensity with sample rates of 10 Hz to 1 kHz. Large pixel scientific CMOS image sensors (sCMOS) are typically used due to their high resolution, high frame rate, and low noise.

Camera parameters estimation from pose detections [PDF]

open access: yesКомпьютерная оптика, 2020
Some computer vision tasks become easier with known camera calibration. We propose a method for camera focal length, location and orientation estimation by observing human poses in the scene.

Temperature and Parasitic Photocurrent Effects in Dynamic Vision Sensors [PDF]

open access: yesIEEE Transactions on Electron Devices, 2017
The effect of temperature and parasitic photocurrent on event-based dynamic vision sensors (DVS) is important because of their application in uncontrolled robotic, automotive, and surveillance applications. This paper considers the temperature dependence of DVS threshold temporal contrast (TC), dark current, and background activity caused by junction ...

Frame Synchronization of High-Speed Vision Sensors with Respect to Temporally Encoded Illumination in Highly Dynamic Environments

open access: yesSensors, 2013
The authors propose a Manchester Encoding inspired illumination modulation strategy to properly index the temporally-aligned vision frames, which are successfully synchronized by the LED reference signal. Based on signal normalization, Manchester Encoded
