GENETIC SEARCH OF A GENERALIZED HOUGH TRANSFORM SPACE

GENETIC SEARCH OF A GENERALIZED HOUGH TRANSFORM SPACE

CONF ON ADAPTIVE AND LEARNING SYSTEMS

作者： MONTANA, DJ Bolt Beranek & Newman Inc. (United States)

ISBN: (纸本)0819408719

We use a Generalized Hough transform (GHT) to detect and track instances of a class of sonar signals. This class consists of a four-dimensional set of curves and hence requires a four- dimensional transform space for the GHT. Many of the signals we need to detect are very weak. Such signals yield peaks in the transform space which are both very narrow and not too far above the random background variations. Finding such peaks is difficult. Exhaustive search over a predetermined discretization of the transform space will yield a nearly optimal point for a sufficiently fine discretization. However, even with an intelligently chosen discretization, exhaustive search requires searching over (and hence evaluating) many points in the transform space. We have therefore developed a genetic algorithm to more efficiently search the transform space. Designing the genetic algorithm to work properly has required experimentation with a number of its parameters. The most important of these are (1) the representation, (2) the population size, and (3) the number of runs.

CONF ON MACHINE VISION APPLICATIONS IN CHARACTER RECOGNITION AND INDUSTRIAL INSPECTION

作者： CHAI, I DORI, D Univ. of Kansas (United States) Technion/Israel Institute of Technology (Israel)

ISBN: (纸本)0819408158

Textboxes are minimum size rectangles enclosing blocks of text in engineering drawings. Their separation from the graphics surrounding them is a first step in character recognition, and is a part of the Machine Drawing Understanding System, currently under development. Textbox extraction is preceded by orthogonal zig-zag vectorization, arc segmentation, and arrowhead recognition. It is done by clustering the remaining short bars that are located close to each other through a region growing process. Further refinements follow which improve the ability of the process to outline the real textboxes.

ISBN: (纸本)0819407879

Attempts to recover images from objects which diffuse radiation pose an especially challenging problem in terms of defining a suitable reconstruction algorithm and with regard to identifying an appropriate computing environment for efficient processing. In this paper we consider both issues and, in particular, describe results of an algebraic technique for imaging the interior of objects which diffuse penetrating radiation using a new multicomputer environment. Two important issues which arise when considering the numerical solution of ultra large problems are the numerical precision achieved and the overall computing efficiency. Our interest in this problem concerns the possibility of obtaining 3-D optical images of tissue which could identify the availability of oxygen by evaluating oxygen- dependent changes in the near infrared spectrum of hemoglobin. These studies were motivated by recent reports from our group and others, which showed promising results for imaging in dense scattering media given only diffusely scattered signals. In our model we assume the use of an NIR laser to provide the input radiation and suitable detectors to measure both transmission and backscatter. In our present work we assume a simple Markov process model for the way in which the energy travels in the medium, but it should be noted that the reconstruction technique we propose can use any model, including nonlinear as well as linear effects, and higher order processes. Current simulations are in 2-D but the methods are easily extended to 3-D. The algorithms we propose are more closely related to algebraic reconstruction algorithms such as ART, SIRT, and SART than to algorithms based on the Born and Rytov approximations such as used for tomographic imaging with diffracting sources. Our algorithms are a significant departure from those based on these standard algebraic methods. We assume only a probabilistic knowledge of the path of the radiation, and minimal knowledge of the absorption

4TH CONF ON THE SIGNAL AND DATA PROCESSING OF SMALL TARGETS 1992

作者： JEWITT, TW General Atronics Corp. (United States)

ISBN: (纸本)0819408638

As a result of an on-going IR&D effort, General Atronics Corporation (GAC) has developed effective algorithms for automatic acquisition, tracking, and recognition of multiple targets - broadly referred to as Automatic Target Recognition (ATR) - using passive sensors on board multiple distributed platforms. The goal of AIR is to either provide timely and accurate assistance to a human operator, who is the ultimate decision maker, or he totally autonomous in extracting the necessary information, its processing, and final decision making. Applications of this technology include Electro-Optical Fire Control Systems (EOFCS), Infrared Search and Track (IRST), Infrared Counter Measures (IRCM), Covert Aircraft Recovery and Tracking Systems (CARTS), Strategic Defense Initiative (SDI), Anti-Submarine Warfare (ASW), Battlefield Intelligence, and Security.

CONF ON IMAGE PROCESSING AND INTERCHANGE : IMPLEMENTATION AND SYSTEMS

作者： BELLON, E WAMBACQ, P SCHOETERS, F LUCKERMANS, S MARCHAL, G SUETENS, P Katholieke Univ. Leuven (Belgium)

ISBN: (纸本)0819408131

A software package to support advanced research in the field of image processing and image analysis must have sufficiently powerful features, especially if it is to be used in a variety of application domains. In this contribution, we present the concepts of the LUCI image processing package, which has been developed in order to meet requirements that have been formulated as a result of previous experiences in our research group. These include support for multi-dimensional images and programming constructs to perform operations on those pixels that are contained in areas of arbitrary shape. In addition, we briefly present support tools for managing this software and its documentation.

1ST CONF ON SCIENCE OF ARTIFICIAL NEURAL NETWORKS

作者： DESSERT, PE Carnegie Group Inc. (United States)

ISBN: (纸本)0819408751

Frequently, time series data taken off machines contains erroneous data points due to errors in the measurement of the data. One such instance of measuring devices recording anomalies occurs in the `crash testing' of vehicles. In this task, senors are placed on the vehicle and the `crash dummy' and the vehicle is then crashed into a barrier. Force and acceleration data is collected which an engineer inspects for anomalies, correcting those that are found. Artificial neural network (ANN) technology was successfully applied to this problem to eliminate the cost and delay of this manual process. To apply ANN technology in this domain, two technical problems needed to be resolved; the appropriate network architecture and the size of the input set. These two issues are quite common and must be addressed in the development of any neural network application. To resolve both issues, I employed a machine learning algorithm that simulates the Darwinian concept of `survival of the fittest' known as the genetic learning algorithm (GLA). By combining the strength of the GLA and ANNs, a network architecture was created that `optimized' the size, speed, and accuracy of the ANN. This `hybridized' system also used the GLA to determine the `smallest' number of inputs into the ANN that were necessary to detect anomalies in data. This algorithm is known as GENENET, and is described in this paper.

CONF ON LASER INTEROMETRY 4 : COMPUTER-AIDED INTERFEROMETRY

作者： BROWN, GM Ford Motor Co. (United States)

ISBN: (纸本)0819406813

Although fully automated phase unwrapping of stepped phase interferograms is a worthy goal and is receiving considerable attention, this Utopian circumstance has not yet been uniquely achieved in a reasonable time on complex real life structures such as an automotive powertrain. The method presented here uses a binary bad spot mask and a seed point mask to phase unwrap the underlying modulo 2(pi) phase map of very complicated structures. Fringe amplitude, modulation, and triangular unit cell path dependence are used to automatically create a portion of the mask. Partition lines are added manually to the mask to separate sheared fringe systems, structural boundaries, and regions of sampling theorem violation.

3RD ANNUAL INTERNATIONAL CONF ON APPLICATIONS OF ARTIFICIAL NEURAL NETWORKS

The newest airborne and spaceborne imaging sensors, unlike their predecessors, generate data at tens to hundreds of wavelengths simultaneously. The advent of these imaging spectrometers greatly increases the detail of the information available to the analyst, but the concomitant disadvantages of vastly increased data volume and complexity have stimulated the search for more efficient and accurate hyperspectral data exploitation techniques. This paper describes two neural network models used in conjunction to analyze hyper-spectral image data. The first neural network is based on an unsupervised backward error propagation model. This network generates without supervision low dimensional discriminant feature vectors from the original high dimensional signals. These features are analyzed by the second neural network, which is a layered feed-forward neural network based on statistical principles, namely Parzen window density estimation and Bayes decision rule. This network estimates class-conditional probability density functions using training samples and classifies data points so that the expected risk is minimized. Results of applying these two neural networks to 210-band AVIRIS data are presented.
