High dynamic range adaptation for ROI tracking based on reconfigurable concurrent dual-sensing
(Institution of Civil Engineers (Great Britain), 2014)
A single-exposure technique to extend the dynamic range of vision sensors is presented. It is particularly suitable for vision algorithms requiring region-of-interest (ROI) tracking under varying illumination conditions. ...

Switched-capacitor networks for scale-space generation
(Institute of Electrical and Electronics Engineers, 2011)
In scale-space filtering signals are represented at several scales, each conveying different details of the original signal. Every new scale is the result of a smoothing operator on a former scale. In image processing, ...

Reaction-diffusion navigation robot control: from chemical to VLSI analogic processors
(Institute of Electrical and Electronics Engineers, 2004)
We introduce a new methodology and experimental implementations for real-time wave-based robot navigation in a complex, dynamically changing environment. The main idea behind the approach is to consider the robot arena as ...

On-site forest fire smoke detection by low-power autonomous vision sensor
(2010)
Early detection plays a crucial role to prevent forest fires from spreading. Wireless vision sensor networks deployed throughout high-risk areas can perform fine-grained surveillance and thereby very early detection and ...

Real-Time Inter-Frame Histogram Builder for SPAD Image Sensors
(Institute of Electrical and Electronics Engineers, 2018)
CMOS image sensors based on single-photon avalanche-diodes (SPAD) are suitable for 2D and 3D vision. Limited by uncorrelated noise and/or low illumination conditions, image capturing becomes nearly impossible in a single-shot ...
