A novel low-voltage reconfigurable ΣΔ modulator for 4G wireless receivers
(2008)
This paper presents a new adaptable cascade ΣΔ modulator architecture fo r low-voltage multi-stan- dard applications. It uses two reconfiguration strategies: a programmable global resonation and a variable loop-filter ...

Random chopping in ΣΔ modulators
(2009)
Σ∆ modulators make a clever use of oversampling and exhibit inherent monotonicity, high linearity and large dynamic range but a restricted frequency range. As a result Σ∆ modulators are often the preferred option for ...

A VLSI-oriented and power-efficient approach for dynamic texture recognition applied to smoke detection
(2009)
The recognition of dynamic textures is fundamental in processing image sequences as they are very common in natural scenes. The computation of the optic flow is the most popular method to detect, segment and analyse dynamic ...

All-MOS implementation of RC networks for time-controlled Gaussian spatial filtering
(Wiley-Blackwell, 2012)
This paper addresses the design and VLSI implementation of MOS-based RC networks capable of performing time-controlled Gaussian filtering. In these networks, all the resistors are substituted one by one by a single MOS ...

Event-driven sensing and processing for high-speed robotic vision
(Institute of Electrical and Electronics Engineers, 2014)
We present here an overview of a new vision paradigm where sensors and processors use visual information not represented by sequences of frames. Event-driven vision is inherently frame-free, ...

Autoregressive time series prediction by means of fuzzy inference systems using nonparametric residual variance estimation
(Elsevier, 2010)
We propose an automatic methodology framework for short- and long-term prediction of time series by means of fuzzy inference systems. In this methodology, fuzzy techniques and statistical techniques for nonparametric ...

Live Demonstration: Single-Exposure HDR Image Acquisition Based on Tunable Balance between Local and Global Adaptation
(Institute of Electrical and Electronics Engineers, 2016)
This live demonstration showcases a high dynamic range technique that compresses wide ranges of illuminations into the available signal range with a single exposure. In order to accomplish such compression, concurrent ...
