作者： P.L. Venetianer P. Szolgay K.R. Crounse T. Roska L.O. Chua Analogical and Neural Computer Laboratory Hungarian Academy of Sciences Computer and Automation Institute Budapest Hungary Department of Electrical Engineering and Computer Sciences ERL University of California Berkeley Berkeley CA USA

This paper demonstrates how certain logic and combinatorial tasks can be solved using CNNs. The most important application generalizes a shortest path algorithm to design the layout of printed circuit boards. Besides, it is shown how cellular automata can be simulated on CNN, and tasks, such as sorting, parity analysis, histogram calculation of black-and-white images, and computing minimum Hamming distance are also solved.< >

This paper investigates manipulation tasks with arrays of microelectromechanical structures (MEMS). We develop a geometric model for the mechanics of microactuators and a theory of sensorless, parallel manipulation, and we describe efficient algorithms for their evaluation. The theory of limit surfaces offers a purely geometric characterization of microscale contacts between actuator and moving object, which can be used to efficiently predict the motion of the object on an actuator array. It is shown how simple actuator control strategies can be used to uniquely align a part up to symmetry without sensor feedback. This theory is applicable to a wide range of microactuator arrays. Our actuators are oscillating structures of single-crystal silicon fabricated in a IC-compatible process. Calculations show that these actuators are strong enough to levitate and move, for example, a piece of paper.< >

In the paper a simulation environment for evaluation of knowledge based fault diagnostic systems is presented. The contribution deals with the concept of the environment that provides an integration of qualitative and quantitative models. This concept is presented on a simulated water-column process controlled by feedback. The simulation environment is used to evaluate the potentials of Multilevel Flow Modelling (MFM) approach to system diagnosis. The environment is realized within the real-time expert system tool G2.

We introduce a collection of techniques, which we propose to denote "neuromorphic CNN", for applying cellular neural networks to the physiologically-detailed modelling of biological neural systems. Examples will be given of the application of these methods to the construction of highly biologically-faithful models of the vertebrate retina, and the utility of such models to neurobiological research will be discussed.< >

In this paper it is shown how the Cellular Neural Network (CNN) can be used to perform image and volume deblurring, with particular emphases on applications to microscopy. We discuss the basic linear theory of the CNN including issues of stability and template size. It is observed that a CNN with a small template can be used to implement an Infinite Impulse Response filter. It is then shown how general deblurring problems can be addressed with a CNN when the blurring operator is known. The proposed application is to solve the basic 3-D confocal image reconstruction task about the form of the blurring operator, confocal behavior in microscope images can be obtained with only 3-5 acquired image planes. In addition, the stored program capability of the CNN Universal Machine would provide integration of several image processing and detection tasks in the same architecture.< >

The computation of 3-D structure from motion using a monocular sequence of images in the paradigm of active vision is investigated in this paper. Robotic tasks such as navigation, manipulation, and object recognition all require 3-D description of scene. The 3-D description for these tasks varies in resolution, accuracy, robustness, range, and time. In developing such a system, it must have the capability to actively control the imaging parameters so that a 3-D description sufficient enough for that task is generated. The objective of this paper is to investigate a strategy suitable for fast and active 3-D structure estimation. First, the process of 3-D structure estimation in the paradigm of active vision is discussed. Second, implication of image streams in 3-D structure computation is analyzed. The three approaches to structure from motion, feature based, optical flow based, and spatial and temporal gradient based, are reviewed for their efficacy in fast and active estimation of 3-D structure. Finally, a pipeline based implementation of a spatial and temporal gradient based approach is presented alongwith detailed experimental analysis. © 1993 SPIE. All rights reserved.

Binocular stereo, vergence stereo, and depth from focus have been extensively studied in isolation in the past for extraction of depth. These passive approaches have there oivn strengths and limitations. All these cues differ in their input image requirements, computational requirements, and the quality and nature of results they provide. None of them by themselves is sufficient to reliably extract depth information from a wide variety of scenes. It is evident an integrated system ivhich employs multiple cues and exploits their strengths would be most critical for developing a robust depth extraction system. Active vision paradigm alloivs us to develop such a system where various depth cues cooperate to derive the 3-D structure of the scene. In this, the integration would be accomplished by active intelligent control of the acquisition processes tightly coupled to the analysis of image data. One of the uniqueness of our integration approach is that while previous approaches have used a single primitive stereo system, typically edgel based, we have chosen a novel multi-primitive hierarchical(MPH) system. In MPH model, stereo analysis is performed in multiple stages, incorporating multiple primitives, utilizing a hierarchical control strategy. The MPH stereo system consists of three integrated subsystems: region based analysis module;linear edge segment based analysis module;and edgel based stereo analysis module. The use of regions and edge segments in addition to the edgel based analysis add a new dimension to the extraction of depth from stereo images. In fact, even in an integrated multiple cue based system, an edgel based binocular stereo approach alone is insufficient to process a variety of scenes. The reliance of different primitives at various levels makes MPH stereo analysis ideal for use in an integrated multiple cue based depth extraction system. © 1993 SPIE. All rights reserved.

Simulation is an indispensable tool for system analysis and design. However, simulation techniques reach quickly their limits or may lose their efficiency when applied to complex systems such as large flexible manufacturing systems or enterprise models. The use of knowledge based technology can enhance the capabilities of simulation by organizing and even eliciting information. Thus enhanced simulators may very well become the primary aid to decision making and planning for large complex systems.< >
