    An overview of present computer techniques of partitioning continuous-tone images into meaningful segments and of characterizing these segments by sets of "features" is presented. Segmentation often consists of two methods:boundary detection and texture analysis. Both of these are discussed. The design of the segmenter and feature extractor are intimately related to the design of the rest of the image analysis system¿particularly the preprocessor and the classifier. Toward aiding this design, a few guidelines and illustrative examples are included. View full abstract»

  • Enhancement of Noisy Images Using an Interpolative Model in Two Dimensions

    The use of two-dimensional interpolative models for recursive enhancement of noisy images is considered. The two-dimensional data is decorrelated either row-wise or column-wise to obtain an equivalent one-dimensional interpolative model. An adaptive identification scheme to identify the parameters of the model is presented which are then used in a simple estimation scheme for recovering the image data. A modification of the FFT algorithm as well as the DCT algorithm are used in decorrelating the data. The performance of these transforms for the present application is compared in terms of the number of computations required and the mean-square error between the enhanced image and the original noise-free image. Several examples are presented to illustrate the applicability of the algorithm. View full abstract»

  • Human Problem Solving Performance in a Fault Diagnosis Task

    It is proposed that humans in automated systems will be asked to assume the role of troubleshooter or problem solver and that the problems which they will be asked to solve in such systems will not be amenable to rote solution. The design of visual displays for problem solving in such situations is considered, and the results of two experimental investigations of human problem solving performance in the diagnosis of faults in graphically displayed network problems are discussed. The effects of problem size, forced-pacing, computer aiding, and training are considered. Results indicate that human performance deviates from optimality as problem size increases. Forced-pacing appears to cause the human to adopt fairly brute force strategies, as compared to those adopted in self-paced situations. Computer aiding substantially lessens the number of mistaken diagnoses by performing the bookkeeping portions of the task. View full abstract»

  • A Study of Dynamic Bilinear Stochastic Models with Applications to Economic Processes

    A new result on the multiplicative and quotient properties of scalar bilinear Ito equations is presented. Employing this result and the well-known closed form solutions for the scalar cases, some Lie theory is used to obtain closed form solutions for a large class of multivariable bilinear Ito differential equations. The closed form solutions are employed to obtain discrete time representations for those systems that can be directly employed in computations. Some computational results for economic system examples are presented. View full abstract»

    Recently, Stallings compared fuzzy set theory with Bayesian statistics. This comparison is improper as it compares Bayesian statistics with a particular case of fuzzy set theory. It is shown here that other interpretation of fuzzy connectives may result in entirely different results. View full abstract»
