— In this paper, we propose a Small-World Cellular Neural Network (SWCNN) model, which is constructed by introducing some random couplings between cells to adding to the original Chua-Yang CNN. Applying this SWCNN model to some applications of image processing such as small object remover, edge detecttiom, etc. are investigated. We found from numerical… (More)
In this paper, we develop a common cellular neural network framework for various adaptive nonlinear filters based on robust statistic and geometry-driven diffusion paradigms. The base models of both approaches are defined as difference-controlled nonlinear CNN templates while the self-adjusting property is ensured by simple analogic (analog and logic) CNN… (More)
The present study investigated neural correlates of affect processing in allodynia patients (n=8) and healthy controls (n=12) with the aid of virtual tactile stimulation. Whole brain functional magnetic resonance imaging was performed for allodynia patients and healthy volunteers while they were shown a video demonstrating light stimulation of the palm and… (More)
In this paper, simple autonomous chaotic circuits coupled by resistors are investigated. By carrying out computer calculations and circuit experiments, irregular self-switching phenomenon of three spatial patterns characterized by the phase states of quasi-synchronization of chaos can be observed from only four simple chaotic circuits. This is the same… (More)
SUMMARY In this study, wave propagation phenomena of phase differences observed in van der Pol oscillators coupled by inductors as a ladder are investigated. The phenomena are called " phase waves. " We classify the observed phenomena and analyze the difference in detail. We observe that the behavior of the phase waves generated by giving a phase difference… (More)
In this study, multimode chaos observed from two coupled chaotic oscillators with hard nonlinearities is investigated. At first, a simple chaotic oscillator with hard nonlinearities is realized. It is confirmed that in this chaotic oscillator the origin is always asymptotically stable and that the solution, which is excited by giving relatively large… (More)
In this study, we propose two types of coupled oscillators networks and investigate their steady states. One network has two-dimensional honeycomb structure. The other network has twedimensional lattice structure. In the Honeycomb circuit, adjacent three oscillators are coupled by one coupling resistor and it is considered that the voltages of three… (More)
SUMMARY Template learning has potential application in several areas of Cellular Neural Network research, including texture recognition, pattern detection and so on. In this letter, a recently-developed algorithm called Adaptive Simulated Anneal-ing is investigated for learning CNN templates, as a superior alternative to the Genetic Algorithm.
