NEURAL-NETWORK PROCESSOR FOR N-MODE FIBER OPTIC SENSORS 4

NEURAL-NETWORK PROCESSOR FOR N-MODE FIBER OPTIC SENSORS

4th International Conference on Applications of Artificial Neural Networks

ISBN: (纸本)0819412015

The n-mode fiber optic sensor built has four linearly polarized (LP) modes propagating simultaneously in the fiber, producing a two-dimensional, spatially distributed output intensity pattern. When the fiber is strained, there is a change in fiber parameters. Oscillating and rotating of the pattern caused by coupling between degenerate modes is observed. Thus the processing of this type of output signal becomes one of a two-dimensional image processor. A neural network signal processor employing a back propagation algorithm was used in conjunction with the few mode fiber optic sensor to categorize the spatial output patterns from the sensor, thus converting the optical pattern to its corresponding strain value. The testing results show that the neural network processor is capable of recognizing this kind of image with good accuracy, resulting in strain accuracies within 0.7 percent.

5TH CONF ON SIGNAL AND DATA PROCESSING OF SMALL TARGETS

作者： WATSON, GA BLAIR, WD Naval Surface Warfare Ctr. (United States)

Since phased array radars have the ability to perform adaptive sampling by the radar beam, proper control of the radar has the potential for significantly improving many aspects associated with the tracking of multiple maneuvering targets. The technique proposed in this paper uses the Interacting Multiple Model (IMM) algorithm to track maneuvering targets and control the sampling time and energy levels. Since the output of the IMM algorithm better represents the accuracy of the state estimates during a maneuver than a single model filter, the IMM algorithm is used to compute and on-line measure of tracking performance to determine the scheduling time of the next track update sample period in order to maintain a given level of performance. The sample time is computed as the one positive root of a polynomial equation of the sample period. The model probabilities of the IMM algorithm are also used to schedule the energy level of a radar dwell. As a result, the update times for the filter are a function of track filter performance and the target trajectory. algorithms for computing the sample time and energy level using the output of the IMM algorithm are developed in this paper. Performance comparisons are given for the IMM algorithm using constant data rates, scheduled energy levels, and adaptive data rates.

DEFINING THE DIGITAL SKELETON

DEFINING THE DIGITAL SKELETON

CONF ON VISION GEOMETRY

作者： PARKER, JR JENNINGS, C Univ. of Calgary (Canada)

ISBN: (纸本)0819410330

The literature on computer vision contains hundreds of references to thinning or skeletonizing, but the only consistent definition for what is meant by a digital skeleton uses the medial axis transform. Most vision researchers would agree that the MAT does not yield an ideal, or in some cases even acceptable, skeleton. For example, single pixel irregularities can produce gross changes in an otherwise simple skeleton. The problem of defining what is meant by skeleton and skeletal pixel is one that has been rarely addressed, but seems crucial. Also, a great amount of past effort has gone into speeding up the thinning process without as much attention to the quality of the result, possibly because no good definition of a skeleton exists. By looking at the extensive literature on the subject some common properties of a good skeleton can be collected, but the process by which the skeleton is found should initially be ignored. This article will describe the properties of the skeleton of a binary object, both historically and by introducing new suggestions. Methods of producing skeletons from this definition will then be discussed, and simple metrics will be used to characterize the 'goodness' of the skeletons. The basic idea is that a skeleton is a global property of a binary object, and that the boundary should be used to locate the skeletal pixels.

CORNER detection FOR CHAIN CODED CURVES

CORNER DETECTION FOR CHAIN CODED CURVES

CONF ON VISION GEOMETRY

作者： KOPLOWITZ, J PLANTE, S Clarkson Univ. (United States) TRW Inc. (United States)

ISBN: (纸本)0819410330

A corner detection scheme for chain coded curves is proposed that significantly improves on the performance of current algorithms. The proposed scheme measures the number of links to either side of a point that can produce the largest digital straight line. That value is used as an indication of curvature at that point with very high curvature being indicative of a corner. A modification of the proposed algorithm can further reduce the false detection rate with virtually no affect on the number of corners missed by omitting certain patterns that can arise from contours with arbitrarily small curvature.

CONF ON SENSOR FUSION AND AEROSPACE APPLICATIONS

作者： ZHENG, QF CHELLAPPA, R Univ. of Maryland/College Park (United States)

ISBN: (纸本)0819411922

An automatic ego motion compensation based point correspondence algorithm is presented. A basic problem in autonomous navigation and motion estimation is automatically detecting and tracking features over consecutive frames, a challenging problem when the camera motion is significant. In general, feature displacement over consecutive frames can be approximately decomposed into two components: (i) the displacement due to camera motion which can be compensated by image rotation, scaling, and translation; (ii) the displacement due to object motion and/or perspective projection. In this paper, we introduce a two step approach: First, the motion of the camera is estimated using a computational vision based image registration algorithm. Then consecutive frames are transformed to the same coordinate system and the feature correspondence problem is solved as one of tracking moving objects using a still camera. Methods for subpixel accuracy feature matching and tracking are introduced. The approach results in a robust and efficient algorithm. Results on several real image sequences are presented.

12th Conference on Intelligent Robots and Computer Vision: algorithms and Techniques

ISBN: (纸本)0819413208

In this paper, a high-resolution algorithm for detecting the orientation and position of an IC, and an algorithm for compensating the position and skew angle of a PCB, are proposed. The proposed algorithm for the first topic consists of two parts. Its first part is a preprocessing step, in which corner points of an IC are detected and are separated into two groups. Then the coarse angle of the principal axis is obtained by line fitting. The second part is a main processing step, in which the Hough transform over the limited range of angles is applied to the corner points to detect precisely the orientation of an IC or a surface mounting device (SMD). The position of an IC or SMD is determined by using its four corner points. The proposed algorithm for the second topic is the one which detects a rotation angle and translation parameters of a PCB using a template matching method. The PCB is compensated by the detected parameters. The computer simulation shows that the parameters obtained by proposed algorithms are more accurate than those by the several conventional methods considered. The proposed algorithms can be applied to the fast and accurate automatic inspection systems.

As we reported previously, a deterministic hard-limited perceptron is a novel learning system in which the learning mechanism is different from most of the conventional learning systems. It is a noniterative, one-step learning system and yet is achieves most of the goals of the conventional learning. If an optimum algorithm is adopted in the design of this learning system, the learning is very fast and the recognition is very robust. This article reports the experimental results of several computer-implemented schemes of this novel learning system. It is seen that the system takes only one to two minutes to train several given patterns and the recognition of the untrained patterns is more than 80% successful. In one scheme, the recognition rate is almost 100% and the recognition is independent of the pattern size, pattern orientation, and pattern location.

CONF ON APPLICATIONS OF ARTIFICIAL INTELLIGENCE 1993 : MACHINE VISION AND ROBOTICS ( PREPRINTS )

作者： HU, XP AHUJA, N Univ. of Illinois/Urbana-Champaign (United States)

ISBN: (纸本)0819412007

General aspects of feature extraction and matching are addressed, which include optimal principles, similarity measures, constraints, and heuristics. The common characteristics of feature extraction and matching are summarized which show that they can be considered as special cases of signal detection. However, the existing signal detection theories do not solve these problems readily. Therefore, a general formulation of feature extraction and matching as a problem of signal detection is desired and presented. This formulation considers feature extraction and matching as similar, subsequent processes, which well integrates the two different processes together to form an automatic system for image matching or object recognition. Guidelines for designing algorithms for detection or matching of arbitrary image features or patterns are derived which can be easily reconfigured for many practical applications. Typical methods and the associated experiments with real image data are provided which demonstrate the superb performance of the methods.

1ST CONF ON SPACE GUIDANCE, CONTROL, AND tracking

作者： DAVIS, S LAI, J Jet Propulsion Lab. (United States)

ISBN: (纸本)081941185X

A ground-based software system to calibrate the attitude control sensors for the Ocean Topography Experiment (TOPEX) spacecraft is described. The algorithm determines sensor misalignment, bias and scale factor errors from gyro, sun sensor and star tracker measurements. The inherent yaw slew motion of the spacecraft during normal mission mode is exploited to make the error parameters observable. A two loop recursive least-squares algorithm is implemented with the feature of inhibiting the update of the error parameter state until all of the available data has been processed. This feature eliminates the estimation state feedback typical of other algorithms which can cause instability and convergence problems.
