    The fuzzy c-shells (FCS) clustering algorithms are widely applied in pattern recognition and computer vision. However, the available FCS algorithms are valid only for detecting the hyper-spherical-shell or hyper-ellipsoidal-shell type clusters, which limits their applications. In this paper, a template based fuzzy c-shells (TBFCS) clustering algorithm is proposed. Its fast implementation is also g... View full abstract»

    Methods based on wavelet transform theory for decreasing sampling noise in feedforward neural networks are proposed in this paper. Wavelet bases are employed in the network to constrain the network's ability in learning samples which are corrupted by noise. The selection of the wavelet bases which correlate with the map to be approximated is mainly discussed View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (192 KB)

    Point processing is one of the most simple and effective methods in image enhancement. Usually, point processing transforms an input image f(i,j) into g(i,j) through a mapping T(*) point by point, that is, g(i,j)=T(f(i,j)). Here, (i,j) is a pixel in these images. This paper puts forward one way of a fast template lookup table algorithm for point processing whose major computations are focused on 2... View full abstract»

    This paper describes three neural network (NN) based approaches for on-line human signature verification: Bayes multilayer perceptrons (BMP), time-delay neural networks (TDNN), and input-oriented neural networks (IONN). The backpropagation algorithm was used for the network training. A signature is input as a sequence of instantaneous absolute velocity (|υ(t)|) extracted from a pair of spatia... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (368 KB)

    We present a new coding method for lossless gray-scale image compression. The method is based on modifications of LZ77-based compression and estimation of prediction errors of pixels. The method gives compression comparable to JPEG lossless mode and its speed is about twice that of JPEG lossless mode with arithmetic coding View full abstract»

  • Digital modulation and IF-filtering of video signals

    Publication Year: 1996, Page(s):1159 - 1161 vol.2
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (184 KB)

    In standard digital video signal processing applications the signal relates to the sampled baseband domain with a typical sampling rate of 13.5 MHz. For digital modulation there is a necessity for a quite higher sampling rate due to the carrier frequency. To avoid an increased expense in video modulation hardware, a special subsampling technique for modulation and an intercarrier frequency filteri... View full abstract»

    The adaptive threshold according to differentiations (ATAD) algorithm proposed utilizes an adaptive threshold which is updated by the first and the second-order differentiations of the signal to compress ECG data. The nature of the signal can be traced and by compressing the higher-information signal regions (QRS complex) and the lower-information regions (isoelectric region, P and T waves and noi...

    A novel algorithm employing polynomial interpolation techniques is proposed for the analysis and resynthesis of musical tones, based on time domain information. This algorithm models a single period of oscillation as a series of features, with curves joining such features together. The trajectories of these features and the shape of the curves across the whole input signal can be parameterised, su... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (252 KB)

    Neural networks with the sub-most and the most tolerant ability for input data are designed on the basis of the fact that sub-most and/or the most tolerant ability can only be obtained by classification hyperplanes which are just through the middle point of the connective line of any adjacent vertices of different logic values in an n-dimensional hypercube and/or orthogonal with the line. The desi... View full abstract»

    This paper proposes a new method to building a fuzzy neural classifier which could be thought as a fuzzy system completed with a neural network. First we need to obtain an initial rule-based fuzzy classifier, then convert this system into a multilayer feedforward neural network architecture.

    The platform rotational motion degrades both detection and estimation performance of passive sonars. Some form of stabilization is required to achieve desirable performance in the presence of such motion. We propose a novel electronic stabilization scheme that improves the performance by mitigating the effect of rotational motion. The proposed scheme compromises between acceptable performance and ...

    Video data is complex, unstructured and voluminous unlike conventional text data. For providing effective retrieval facilities, video data needs to be stored in a database with an appropriate data structure. Hence, identifying the required information units and formulating a data structure have become the fundamental tasks. Data mining methods analyze data for extracting patterns. In this paper, w...

    Direction coding is a new method of image coding. The human visual model is used to make direction filters and high compression ratios are obtained. Direction coding not only deals with the continuous component of an image by subsampling it with high compression ratio, but also does some things with the discontinuous component of the image. We apply the direction coding method to narrowband image ... View full abstract»

    An approach is proposed for segmented image coding which avoids the redundant and false-edges that appear in the late stages of hierarchical segmentation. The recursive shortest spanning tree (RSST) algorithm is used to obtain regions describing the main objects. Significant small features are then extracted from the original image to compensate for the coarse segmented image. The method of extrac... View full abstract»
