Parameterizations of digital surfaces homeomorphic to a sphere using discrete harmonic functions
Authors: Ola Weistrand
Venue: Pattern Recognition Letters (2006)

We discuss how to map simply connected digital surfaces to the unit sphere using discrete harmonic functions. This technique is well known for constructing parametrizations of surfaces onto simpler domains. A common problem is the creation of dense clusters of vertices, which leads to numerical instability of methods operating on this mapping. By an explicit calculation, we quantify the cluster density for a simple model example. This example shows that distances between mapped vertices can decrease exponentially in regions on the sphere. By numerical examples, we show that severe clustering often occurs for natural objects. A computationally inexpensive algorithm, based on a bijective transformation of the unit sphere, is suggested for post-processing of clusters. Experiments indicate that this algorithm often improves the mapping such that convergence of a non-linear optimization program is achieved. The program aims at optimizing the parameterization, making it useful for global shape analysis. Examples of approximations in terms of spherical harmonics functions are presented.
Logic Synthesis Method for Dual-Rail RSFQ Digital Circuits Using Root-Shared Binary Decision Diagrams
Authors: Koji Obata, Kazuyoshi Takagi, Naofumi Takagi
Venue: IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences (2007)

We propose a new method of logic synthesis for dual-rail RSFQ (rapid single-flux-quantum) digital circuits. RSFQ circuit technology is one of the strongest candidates for the next generation technology of digital circuits. For representing logic functions, we use a root-shared binary decision diagram (RSBDD) which is a directed acyclic graph constructed from binary decision diagrams. In the method, first we construct an RSBDD from given logic functions, and then reduce the number of nodes in the constructed RSBDD by variable re-ordering. Finally, we synthesize a dual-rail RSFQ circuit from the reduced RSBDD. We have implemented the method and have synthesized benchmark circuits. We have synthesized dual-rail circuits that consist of about 27% fewer logic elements than those synthesized by a Transduction-based method on average.

On the impact of fusion strategies on classification errors for large ensembles of classifiers
Authors: João B. D. Cabrera
Venue: Pattern Recognition (2006)

The growing availability of sensor networks brings practical situations where a large number of classifiers can be used for building a classifier ensemble. In the most general case involving sensor networks, the classifiers are fed with multiple inputs collected at different locations. However, classifier fusion is often studied within an idealized formulation where each classifier is fed with the same point in the feature space, and estimate the posterior class probability given this input. We first expand this formulation to situations where classifiers are fed with multiple inputs, demonstrating the relevance of the formulation to situations involving sensor networks, and a large number of classifiers. Following that, we determine the rate of convergence of the classification error of a classifier ensemble for three fusion strategies (average, median and maximum) when the number of classifiers becomes large. As the size of the ensemble increases, the best strategy is defined as the one that results in fastest convergence of the classification error to zero. The best strategy is analytically shown to depend on the distribution of the individual classification errors: average is the best for normal distributions; maximum is the best for uniform distributions; and median is the best for Cauchy distributions. The general effect of heavy-tailedness is also analytically investigated for the average and median strategies. The median strategy is shown to be robust to heavy-tailedness, while performance of the average strategy is shown to degrade as heavy-tailedness becomes more pronounced. The combined effects of bimodality and heavy-tailedness are also investigated when the number of classifiers become large.
Proposal for a program support facility
Authors: Jon Sachs
Venue: ACM SIGDOC Asterisk Journal of Computer Documentation (1975)

This paper presents a preliminary definition of a program support facility (PSF). A PSF supports a programming effort with reporting operations and documentation. It interacts with other software running on the host operating system, and thus can perform many of its functions automatically.The properties of a PSF are described here in the context of IBM's OS/360 or 370, but the principles are applicable to any hardware and operating system sophisticated enough to support them.

Image analysis by modified Legendre moments
Authors: Bo Fu, Jianzhong Zhou, Yuhong Li, Guojun Zhang, Cheng Wang
Venue: Pattern Recognition (2007)

In the paper, a new set of orthogonal moments based on the modified Legendre polynomials is introduced. Three properties of the modified Legendre polynomials, which are orthogonality, orthogonal invariance and the characteristic that an interval on the center of [-1,1] covers more zeros than do that on the edge of [-1,1], are discussed detailedly. The orthogonality of the proposed moments ensures minimal information redundancy in a moment set. The orthogonal invariance of the proposed polynomials makes the proposed moments have the property of translation invariance. And, the third property ensures that the modified Legendre moments have superior feature representation capabilities over Legendre moments in analyzing small images. For small images, the description by the modified Legendre moments is better than that by the Legendre moments and the Chebyshev moments in terms of image-reconstruction errors. Theoretical and experimental measures of performance are carried out to investigate the image-representation capabilities of the proposed moments for images and noisy-images. The computational aspects of the moments using recurrence, integral, symmetry and translation invariance are also discussed. Experimental results are shown.

Modelling catastrophe claims with left-truncated severity distributions
Authors: Anna Chernobai, Krzysztof Burnecki, Svetlozar Rachev Stefan Trück, Rafał Weron
Venue: Computational Statistics (2006)

In this paper, we present a procedure for consistent estimation of the severity and frequency distributions based on incomplete insurance data and demonstrate that ignoring the thresholds leads to a serious underestimation of the ruin probabilities. The event frequency is modelled with a non- homogeneous Poisson process with a sinusoidal intensity rate function. The choice of an adequate loss distribution is conducted via the in-sample goodness-of-fit procedures and forecasting, using classical and robust methodologies.

Real time multiple objects tracking and identification based on discrete wavelet transform
Authors: Fang-Hsuan Cheng, Yu-Liang Chen
Venue: Pattern Recognition (2006)

A new method for detecting and tracking multiple moving objects based on discrete wavelet transform and identifying the moving objects by their color and spatial information is proposed in this paper. Many tracking algorithms have better performance under static background but get worse results under background with fake motions. Therefore, most of the tracking algorithms are used indoors instead of outdoor environment. Since discrete wavelet transform has a nice property that it can divide a frame into four different frequency bands without loss of the spatial information, it is adopted to solve this problem due to the fact that most of the fake motions in the background can be decomposed into the high frequency wavelet sub-band. In tracking multiple moving objects, many applications have problems when objects pass across each other. Color and spatial information are used in this paper to solve this problem. The experimental results prove the feasibility and usefulness of the proposed method.
Intranet: A medium of internal communication and training
Authors: Violetta Bottazzo
Venue: Information Services and Use (2005)

In addition to knowledge, the flow of information or efficient organisational communication is an essential condition for the successfulness of every organisation. Although the ideal vertical and horizontal communication is difficult to achieve, training-informational centres and special libraries should also strive to achieve this goal. Advantages of available communication technology, especially the Intranet, should be taken for this purpose as much as possible. The control of the field of management or knowledge transfer is a complex problem, which is practically unmanageable without the tool for knowledge dissemination. This is the reason why portals are used more and more. It is common to them that these are starting pages, where basic information is gathered in a condensed form; portals are starting points for more detailed information. They function on the basis of the technology supported by browsers. The topic of this paper is the development of an organisation in the process of learning, especially the need analysis of an organisation and setting up of a training portal as a tool for Intranet training, submission and flow of information.
Named entity recognition in a South African context
Authors: Anita Louis, Alta De Waal, Cobus Venter
Venue: Proceedings of the 2006 annual research conference of the South African institute of computer scientists and information technologists on IT research in developing countries (2006)

The feasibility of a probabilistic Named Entity Recognition system in a South African context was tested. The intended use of the system is in a cyber forensic domain. At the core of the system is a dynamic Bayesian Network, which takes into account the probabilistic relationship between variables as well as contextual information. We illustrate the performance of such a system using different probability thresholds for classification purposes and compare the performance with and without a name gazetteer. Our system compares competently with similar existing systems in the information extraction domain. Future work will involve the application of the system in the cyber forensic environment, which poses new challenges such as diverse text types.

Multi time scale differential equations for simulating frequency modulated signals
Authors: R. Pulch
Venue: Applied Numerical Mathematics (2005)

Radio-frequency (RF) circuits produce quasiperiodic signals with widely separated time scales. In the case of autonomous time scales, frequency modulation occurs in addition to amplitude modulation. A multidimensional signal model yields an efficient numerical simulation by computations via a multirate partial differential algebraic equation (MPDAE) with periodic boundary conditions. We present a time domain method for these systems, which integrates along characteristic curves and thus is consistent with the inherent information transport. Moreover, we propose a special choice for additional boundary conditions, which are necessary to determine local frequencies. Test results confirm that the constructed techniques compute efficiently frequency modulated quasiperiodic signals in RF applications.

Automatic texture feature selection for image pixel classification
Authors: Domenec Puig, Miguel Angel Garcia
Venue: Pattern Recognition (2006)

Pixel-based texture classifiers and segmenters are typically based on the combination of texture feature extraction methods that belong to a single family (e.g., Gabor filters). However, combining texture methods from different families has proven to produce better classification results both quantitatively and qualitatively. Given a set of multiple texture feature extraction methods from different families, this paper presents a new texture feature selection scheme that automatically determines a reduced subset of methods whose integration produces classification results comparable to those obtained when all the available methods are integrated, but with a significantly lower computational cost. Experiments with both Brodatz and real outdoor images show that the proposed selection scheme is more advantageous than well-known general purpose feature selection algorithms applied to the same problem.
