This paper introduces a novel neural architecture which is capable of similar performance to any of the 'classic' neural paradigms while having a very simple and efficient mixed-signal implementation which makes it a valuable candidate for intelligent signal processing in portable multimedia applications. The architecture and its realization circuit are described and the functional capabilities of the novel neural architecture called a simplicial neural cell are demonstrated for both regression and classification problems including nonlinear image filtering. Index Terms--Cellular neural networks, feedforward neural networks, image reconstruction, mixed analog-digital integrated circuits, pattern classification, piecewise linear (PWL) approximation.

In this study, we present the initial results of cellular neural network (CNN)-based autowave metric to high-speed pattern recognition of gray-scale images, the application is to a problem involving separation of metallic wear deris particles from air bubbles. This problem arises in an optical-based system for determination of mechanical wear. This paper focuses on distinguishing debris particles suspended in the oil flow from air bubbles and aims to employ CNN technology to create an online fault monitoring system. For the class of engines of interest bubbles occur much more often than debris particles and the goal is to develop a classification system with an extremely low false alarm rate for missclassififed bubbles. The designed analogic CNN algorithm detects and classifies single ubbles and bubble groups using inary morphology and autowave metric. The debris particles are separated based on autowave distances computed btween bubble models and the unknown objects. Initial experiments indicate that the proposed algorithm is robust and noise tolerant and when implemented on a CNN universal chip it provides a solution in real time.
