This paper presents a tabular technique for calculation of fixed-polarity polynomial expressions for MV functions. The technique is derived from a generalization of the corresponding methods for Fixed-Polarity Reed-Muller (FPRM) expressions for switching functions. All useful features of tabular techniques for FPRMs, as for example, simplicity of involved(More)
ÐDiscrete Walsh transform is an orthogonal transform often used in spectral methods for different applications in signal processing and logic design. FFT-like algorithms make it possible to efficiently calculate the discrete Walsh spectrum. However, for their exponential complexity, these algorithms are practically unsuitable for large functions. For this(More)
In this paper, we present a system based on feature extraction techniques and image segmentation techniques for detecting and diagnosing abnormal patterns in breast thermograms. The proposed system consists of three major steps: feature extraction, classification into normal and abnormal pattern and segmentation of abnormal pattern. Computed features based(More)
In this paper we propose a method for optimization of fixed polarity arithmetic expressions (FPAEs) based on dual polarity. The method exploits a simple relationship between two FPAEs for dual polarities. It starts from the zero polarity FPAE of the given function and calculates all FPAEs using dual polarity route. Conversion from one FPAE to another one is(More)
