Stereopsis or depth perception is a critical aspect of information processing in the brain and is computed from the positional shift or disparity between the images seen by the two eyes. Various algorithms and their hardware implementation that compute disparity in real time have been proposed; however, most of them compute disparity through complex mathematical calculations that are difficult ...

Along with the creation of new maps, current efforts for improving global land cover (GLC) maps focus on integrating maps by accounting for their relative merits, e.g., agreement amongst maps or map accuracy. Such integration efforts may benefit from the use of multiple GLC reference datasets. Using available reference datasets, this study assesses spatial accuracy of recent GLC maps and compar...

We present an analog circuit implementation of the novel partial control method, that is able to sustain chaotic transient dynamics. The electronic circuit simulates the dynamics of the onedimensional slope-three tent map, for which the trajectories diverge to infinity for nearly all the initial conditions after behaving chaotically for a while. This is due to the existence of a nonattractive c...

The external behavior of linear resistive circuits with terminals is characterized as a linear input–output map given by a weighted Laplacian matrix. Conditions are derived for shaping the external behavior of the circuit by interconnection with an additional resistive circuit. © 2010 Elsevier B.V. All rights reserved.

یکی از مسائلی که در سیستم sar مطرح می شود مسأله نویز speckle می باشد. منبع تولید نویز speckle فاز نسبی پراکنده گرهای مختلف در یک سلول رادار می باشد که نوسانات شدیدی در سیگنال دریافتی به وجود آورده و تصویر حاصل را دانه دانه می نماید. این نویز تفسیر تصاویر را مشکل و اطلاعات زیادی را مخفی می کند و لذا کاهش آن یکی از ملزومات در پردازش سیگنال sar است. الگوریتمهای متعددی جهت کاهش نویز speckle در نوا...

This letter studies a simple nonautonomous chaotic circuit constructed by adding an impulsive switch to the RCL circuit. The switch operation depends on time and on state variable through a refractory threshold. The circuit exhibits various chaotic attractors, periodic attractors and related bifurcation phenomena. The dynamics can be analyzed using 1-D return map focusing on the time-dependent ...

This paper presents a spiking neuron circuit with a triangular base signal. The circuit can output rich pulse-trains and the dynamics can be analyzed using a piecewise linear one-dimensional pulse-position map. Applying cross-switching to two neurons we construct a pulse-coupled system whose dynamics can be integrated into a composite map of the pulse position maps of two neurons. The composite...

| In this paper we describe a new technique for proving that a particular system is chaotic in topological sense, i.e. that it has positive topological entropy. This technique combines existence results based on the xed point index theory and computer-assisted computations, necessary to verify assumptions of the existence theorem. First we present an existence theorem for periodic points of map...
