Library for model-based design of image processing algorithms on FPGAs
(Universidad Pedagógica y Tecnológica de Colombia, 2013)
This paper describes a library (XSGImgLib) that includes parameterizable blocks to implement low-level image processing tasks on FPGAs. A modelbased design technique provided by Xilinx System Generator (XSG) has been used ...

Boundary cost optimization for Alternate Test
(Institute of Electrical and Electronics Engineers, 2015)
Alternate Test has demonstrated in the last decade that advanced machine-learning tools can leverage the accuracy gap between functional test and indirect, or model-based, test. If a regression approach is taken, a model ...

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 ...

An Event-Driven Classifier for Spiking Neural Networks Fed with Synthetic or Dynamic Vision Sensor Data
(Frontiers Media, 2017)
This paper introduces a novel methodology for training an event-driven classifier within a Spiking Neural Network (SNN) System capable of yielding good classification results when using both synthetic input data and real ...

Simplified state update calculation for fast and accurate digital emulation of CNN dynamics
(Institute of Electrical and Electronics Engineers, 2010)
Compared to other one-step integration methods, the 4th-order Runge-Kutta is much more accurate while still consisting in a rather reduced algorithmic structure. However, in terms of the computing power, it is more expensive ...

Embedded face detection application based on local binary patterns
(Institute of Electrical and Electronics Engineers, 2015)
In computer vision during the recent years a new paradigm for object detection has stimulated researchers and designers interest. The foundation of this new paradigm is the Local Binary Pattern (LBP) which is a nonparametric ...

Offset-calibration with Time-Domain Comparators Using Inversion-mode Varactors
(Institute of Electrical and Electronics Engineers, 2019)
This paper presents a differential time-domain comparator formed by two voltage controlled delay lines, one per input terminal, and a binary phase detector for comparison solving. The propagation delay through the respective ...

Compressive image sensor architecture with on-chip measurement matrix generation
(Institute of Electrical and Electronics Engineers, 2017)
A CMOS image sensor architecture that uses a cellular automaton for the pseudo-random compressive sampling matrix generation is presented. The image sensor employs in-pixel pulse-frequency modulation and column wise pulse ...
