    This paper presents a method of cluster analysis based on a pseudo F-statistic (PFS) criterion function. It is designed to subdivide an ensemble into an optimal set of groups, where the number of groups is not specified and no ad hoc parameters are employed. Univariate and multivariate F-statistic and pseudo F-statistic consistency is displayed. Algorithms for feasible application of PFS are given... View full abstract»

  • A Method of Recognition and Representation of Korean Characters by Tree Grammars

    A syntactic method is applied to the recognition of Korean characters (Hangul). Since they develop into complex characters by the sequential addition of fundamental characters under positioning rules, there are a large amount of characters and consequently there exist many similar characters. Therefore, the sequential extraction, according to the positioning rules, of fundamental characters compos... View full abstract»

  • Texture Analysis Using Generalized Co-Occurrence Matrices

    We present a new approach to texture analysis based on the spatial distribution of local features in unsegmented textures. The textures are described using features derived from generalized co-occurrence matrices (GCM). A GCM is determined by a spatial constraint predicate F and a set of local features P = {(Xi, Yi, di), i = 1,..., m} where (Xi, Yi) is the location of the ith feature, and di is a ...

  • A Random Walk Procedure for Texture Discrimination

    We consider the problem of texture discrimination. Random walks are performed in a plain domain D bounded by an absorbing boundary ¿ and the absorption distribution is calculated. Measurements derived from such distributions are the features used for discrimination. Both problems of texture discrimination and edge segment detection can be solved using the same random walk approach. The border dis... View full abstract»

  • Translation of Fuzzy Queries for Relational Database System

    The concept of a database skeleton which reflects both the user's conception of the real world and the system's understanding of the interrelationships among database entities is described. It consists of a conceptual schema (conceptual graphs) and a relational schema (information graph). With the aid of the database skeleton, fuzzy queries can be translated and disambiguated by analyzing the quer... View full abstract»

    Algorithms are presented for converting between different three-dimensional object representations: from a collection of cross section outlines to surface points, and from surface points to a collection of overlapping spheres. The algorithms effect a conversion from surface representations (outlines or surface points) to a volume representation (spheres). The spherical representation can be useful... View full abstract»

  • A Problem of Dimensionality: A Simple Example

    In pattern recognition problems it has been noted that beyond a certain point the inclusion of additional parameters (that have been estimated) leads to higher probabilities of error. A simple problem has been formulated where the probability of error approaches zero as the dimensionality increases and all the parameters are known; on the other hand, the probability of error approaches one-half as...

    Graphical techniques are presented for estimating Hough transform performance for detecting straight lines in noisy digital pictures. The methods show explicitly the influence of noise due, for example, to quantizing errors on the accuracy of estimating the underlying sets of collinear points. Exact bounds are obtained for sets of collinear points showing that under quite general conditions only t... View full abstract»

    Complex waveforms may contain peaks and valleys at many different scales, ranging from very local to very global. This correspondence describes an approach to detecting these peaks and valleys by applying simple difference operators at each point to neighborhoods having a wide range of sizes, and making simple comparisons of the outputs of these operators for various sizes and positions.

    The problem of matching two images of the same scene, taken by different sensors under different viewing geometries, is a challenging problem in the field of image processing and pattern recognition. The scenes are usually transformed so drastically by the different viewing geometries and sensor characteristics that it is extremely difficult, if not impossible, to match the original images without...
