Model-based design for selecting fingerprint recognition algorithms for embedded systems
(2012)
Most of contributions for biometric recognition solutions (and specifically for fingerprint recognition) are implemented in software on PC or similar platforms. However, the wide spread of embedded systems means that ...

Circuit implementation of piecewise-affine functions based on lattice representation
(Institute of Electrical and Electronics Engineers, 2011)
This paper introduces a digital architecture to implement piecewise-affine (PWA) functions based on representation methods from the lattice theory. Given an explicit and continuous PWA function, the parameters required to ...

Multi-band high-impedance surface absorbers with a single resistive sheet: Circuit theory model
(Institute of Electrical and Electronics Engineers, 2011)
We present a simple and efficient circuit model for the analysis of multi-band absorption characteristics of a stack of sub-wavelength grids (fishnets or patch arrays) in a layered environment with a single resistive sheet ...

A 176x144 148dB adaptive tone-mapping imager
(Society of Photo-Optical Instrumentation Engineers, 2012)
This paper presents a 176x144 (QCIF) HDR image sensor where visual information is simultaneously captured and adaptively compressed by means of an in-pixel tone mapping scheme. The tone mapping curve (TMC) is calculated ...

Efficient realization of RTD-CMOS logic gates
(2011)
The incorporation of Resonant Tunnel Diodes (RTDs) into III/V transistor technologies has shown an improved circuit performance: higher circuit speed, reduced component count, and/or lowered power consumption. Currently, ...

Equivalent circuits for conventional and extraordinary reflection in dipole arrays
(Institute of Electrical and Electronics Engineers, 2011)
This presents an equivalent transmission-line circuit that accounts for the scattering of a TE polarized plane wave that impinges obliquely on a periodic array of metallic patches sandwiched in a dielectric slab. The ...

Demo: Results of 'iCaveats', a Project on the Integration of Architectures and Components for Embedded Vision
(ACM Digital Library, 2018)
iCaveats is a Project on the integration of components and architectures for embedded vision in transport and security applications. A compact and efficient implementation of autonomous vision systems is difficult to be ...

Analytical circuit model for stacked slit gratings
(Institute of Electrical and Electronics Engineers, 2014)
This work presents a rigorous circuit model to compute the transmission/reflection properties of a finite number of stacked slit gratings printed on dielectric slabs of arbitrary thickness. A key aspect of the present ...

Reducing bit flipping problems in SRAM physical unclonable functions for chip identification
(Institute of Electrical and Electronics Engineers, 2012)
Physical Unclonable functions (PUFs) have appeared as a promising solution to provide security in hardware. SRAM PUFs offer the advantage, over other PUF constructions, of reusing resources (memories) that already exist ...

Using physical unclonable functions for internet-of-thing security cameras
(Springer, 2018)
This paper proposes a low-cost solution to develop IoT security cameras. Integrity and confidentiality of the image data are achieved by cryptographic modules that implement symmetric key-based techniques which are usually ...
