    Many image segmentation methods based on clustering are available in the literature. Some of these techniques use classical clustering, some use fuzzy sets. Most of these techniques are not suitable for noisy environments. Some work has been done using the possibilist clustering approach which is robust to noise, but requires knowledge of the number of clusters. The probabilistic approach can be u...

    To trace an explicit function, many items of software (for example: Matlab, Mathcad, Mathematica, Gnuplot, ..., under MS-DOS, UNIX, Windows) have been made. The method in theory is simple: if the value of the argument x is given, then we can calculate the value of the function y, as an expression of the given function. To trace an implicit function, there is not at present any efficient method bec... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (292 KB)

    The CW signal and FM signal are two kinds of common signals used in an active sonar system. In a sonar auditory set, the CW signal can achieve a clear, good result, but this is not easy for the FM signal. In order to improve the unsatisfactory result, this paper presents a mew method to convert the FM signal into a CW signal with a neural network. Computer simulation has proved the feasibility and...

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (304 KB)

    In pattern recognition applications sometimes we need to classify pattern samples under the circumstances of lacking priori knowledge, such as the number of classes, the distribution of classes, etc. or having a complicated distribution of classes in the characteristic space. A new clustering algorithm is presented to realize clustering with an unknown number of classes and with an unknown or comp... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (348 KB)

    We present here a new class of activation functions for neural networks, which is called the CosGauss function. This function is a cosine-modulated Gaussian function. In contrast to the sigmoidal-, hyperbolic tangent- and Gaussian activation functions, more ridges can be obtained by the CosGauss function. It is proved that this function can be used to approximate polynomials and step functions. Th... View full abstract»

  • Wavelets and dynamic pattern recognition

    Publication Year: 1996, Page(s):1304 - 1307 vol.2
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (312 KB)

    The spectral analysis in the spirit of traditional Fourier transform does not preserve the time dependence of the patterns when a signal is nonstationary. Wavelet analysis, on the other hand, has emerged as a remarkable tool for decomposition of functions. General procedures of wavelet-based regression estimators assume the time-invariant coefficients. To accommodate the stochastic and dynamic pro... View full abstract»
