    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...

    This research is aimed at improving understanding of the execution of human skilled movements in the saggital plane. Towards this aim a model-based approach that consists of the following steps is adopted: (a) a physiologically-motivated model of the lower extremity is developed; (b) a neurophysiological controller with neural activation and intrinsic/peripheral feedback is designed; (c) an optimi...

    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»

    This paper focuses on the problem of image segmentation. It addresses the inherent deficiencies occurring when extracting low-level features (primitives) and when dealing with the complexity of real scenes. To solve such a problem we propose a general framework which integrates several types of primitives formed progressively from different complementary transformations of the image in an iterativ...

    Positron emission tomography (PET) is a functional imaging modality which provides information on in vivo physiological and metabolic functions in the human body. However, the long reconstruction time has prevented 3D PET from being practical. To make 3D PET feasible in a medical environment, in this paper, we propose an efficient parallel architecture for PET image reconstruction. The proposed pa... View full abstract»

    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»

  • Wavelet transformation image coding based on the human visual specificity

    Request permission for commercial reuse | Click to expandAbstract |PDF file iconPDF (440 KB)

    A new method based on wavelet theory has been developed for low bit rate coding of image. The wavelet transform results in a logarithmic division of frequency space which can be justified by relevance to human visual system models and allows each frequency band to be efficiently coded. In order to achieve low bit rate, two new coding schemes respectively based on scalar quantisation (SQ) and vecto... View full abstract»

  • High-order entropy coding of medical image data using different binary-decomposed representations

    Publication Year: 1996, Page(s):886 - 889 vol.2
    Request permission for commercial reuse | Click to expandAbstract |PDF file iconPDF (352 KB)

    Information theory indicates that the coding efficiency can be improved by utilizing high-order entropy coding (HOEC). However, serious implementation difficulties limit the practical value of HOEC for grayscale image compression. We present a new approach, called binary-decomposed (BD) high-order entropy coding, that significantly reduces the complexity of the implementation and increases the acc... View full abstract»

    The article provide an improvement of the method of Bendiksen et. al. (1990) adopting the backpropagation (BP) network for voiced/unvoiced speech classification, by using the HRFNN, adapting it to the non-linear pronunciation model. The comparison test has shown that the HRFNN has a 100 times higher training rate than the BP network and the recognition accuracy is better than the BP network. As fo... View full abstract»

    A multiresolution method to match deformed contours is presented. Our approach has been inspired by the method due to Duncan et al. (1990) and Cohen et al. (1992). The innovation of our work is in the incorporation of a new smoothness term in the elastic fitting criterion. As a result the computational complexity is reduced and the equation corresponding to the minimization of the fitting criterio... View full abstract»

    In this paper we present a real-time lane mark line following system used for high speed ALV navigation on structural road. The white line on black ground is obtained by the color transform of the input RGB image. The white line head is searched by a local thresholding and hypothesis-verification method. A window searching scheme with local projection and voting is described. Both sides of the lan... View full abstract»

    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»

    This paper proposes a new object representation scheme called hierarchical extended Gaussian image (HEGI). The HEGI can be used for describing nonconvex as well as convex objects. The HEGI description can be constructed as a tree where each leaf node corresponds to an extended Gaussian image (EGI) description of a convex part resulting from the recursive convex hull decomposition of an object.

    We propose a new segmentation algorithm for object extraction as a part of a region based coding scheme. The segmentation is based on spatial and temporal information with emphasis on the shape consistency of the region. The segmentation algorithm presented here utilizes splitting of the region into smaller regions based on edge information, followed by merging using motion similarity and shape co...

    Linear and non-linear separability of Boolean functions are difficult problems in feedforward neural networks. Only linear separability of Boolean functions with the number of variables n<7 had been discussed before. In this paper, a tolerantly linear-separable complexity of Boolean functions is defined to simplify discussions and optimize solutions. An approach of numbering Boolean functions w...
