On the design of a sparsifying dictionary for compressive image feature extraction
(Institute of Electrical and Electronics Engineers, 2015)
Compressive sensing is an alternative to Nyquist-rate sampling when the signal to be acquired is known to be sparse or compressible. A sparse signal has a small number of nonzero components compared to its total length. ...

Real-time single-exposure ROI-driven HDR adaptation based on focal-plane reconfiguration
(Society of Photo-Optical Instrumentation Engineers, 2015)
This paper describes a prototype smart imager capable of adjusting the photo-integration time of multiple regions of interest concurrently, automatically and asynchronously with a single exposure period. The operation is ...

Wi-FLIP: A wireless smart camera based on a focal-plane low-power image processor
(Institute of Electrical and Electronics Engineers, 2011)
This paper presents Wi-FLIP, a vision-enabled WSN node resulting from the integration of FLIP-Q, a prototype vision chip, and Imotel, a commercial WSN platform. In Wi-FLIP, image processing is not only constrained to the ...

Arrayable Voltage-Controlled Ring-Oscillator for Direct Time-of-Flight Image Sensors
(Institute of Electrical and Electronics Engineers, 2017)
Direct time-of-flight (d-ToF) estimation with high frame rate requires the incorporation of a time-to-digital converter (TDC) at pixel level. A feasible approach to a compact implementation of the TDC is to use the multiple ...

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, ...

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 ...

In-pixel generation of gaussian pyramid images by block reusing in 3D-CMOS
(Institute of Electrical and Electronics Engineers, 2012)
This paper introduces an architecture of a switched-capacitor network for Gaussian pyramid generation. Gaussian pyramids are used in modern scale- and rotation-invariant feature detectors or in visual attention. Our ...
