Cellular neural networks for motion estimation and obstacle detection
No full textObstacle detection is an important part of Video Processing because it is indispensable for a collision prevention of autonomously navigating moving objects. For example, vehicles driving without human guidance need a robust prediction of potential obstacles, like other vehicles or pedestrians. Most of the common approaches of obstacle detection so far use analytical and statistical methods like motion estimation or generation of maps. In the first part of this contribution a statistical algorithm for obstacle detection in monocular video sequences is presented. The proposed procedure is based on a motion estimation and a planar world model which is appropriate to traffic scenes. The different processing steps of the statistical procedure are a feature extraction, a subsequent displacement vector estimation and a robust estimation of the motion parameters. Since the proposed procedure is composed of several processing steps, the error propagation of the successive steps often leads to inaccurate results. In the second part of this contribution it is demonstrated, that the above mentioned problems can be efficiently overcome by using Cellular Neural Networks (CNN). It will be shown, that a direct obstacle detection algorithm can be easily performed, based only on CNN processing of the input images. Beside the enormous computing power of programmable CNN based devices, the proposed method is also very robust in comparison to the statistical method, because is shows much less sensibility to noisy inputs. Using the proposed approach of obstacle detection in planar worlds, a real time processing of large input images has been made possible
Memristor Emulators: A Note on Modeling
No full textIn a recent publication (Yi et al. 2011) elucidating a possible scheme to
write information reliably onto a memory crossbar,Hewlett Packard Labs researchers
employed a thyristor-based circuit to emulate the off-to-on switching behaviour of a
titanium oxide memristor. The use of a thyristor device allowed them to test inexpensively
and reliably the functionalities of the closed-loop crossbar write circuitry
by using conventional CMOS components. From a device modeling point of view,
however, it is worthy to point out that the aforementioned emulator is not a genuine
memristor. The aim of this paper is to demonstrate with an in-depth mathematical
analysis that the model of the thyristor does not fall into the class of memristors.
The modelling approach adopted in this work may be a source of inspiration for
researchers willing to check whether other devices or circuits may be classified as
memristors
Dormiunt aliquando leges, numquam moriuntur. The phenomenon of judicial and moral judgment on the example of the novella Mondlicht über Masuren [Moonlight on Masuria] by Günther Tetzlaff
No full textIm Mittelpunkt des vorliegenden Beitrags steht der Versuch eines Vergleichs des gerichtlichen und moralischen Urteils am Beispiel der Novelle von Günther Tetzlaff Mondlicht über Masuren. Die Frage wird sowohl im Hinblick auf die Nuancen der Urteilssprechung, auf die besondere Rolle des Schriftstellers und Juristen, der auf eine ungewöhnliche Weise sein Urteil abgibt, indem er die Grenzen der menschlichen Wahrnehmung überschreitet, als auch auf die gesellschaftliche Beurteilung untersucht. Der Kontext wird ferner durch Einbeziehung des rechtswissenschaftlichen Problems der Berufsethik des Richters sowie durch psychoanalytische und esoterische Aspekte erweitert.The article deals with the problem of moral vs. legal judgment as presented in the novella Mondlicht über Masuren by Günther Tetzlaff. This problem appears in the seeking for judgment, in the comportment of individual and collective judgment makers, but especially in the role of the writer-lawyer who crosses the limits of human cognition. All this goes with a discussion of the ethics of the judge in jurisprudence as well as with psychoanalytical and esoteric aspects
