In this paper, a new nonlinear median based filtering technique is introduced for the enhancement of medical images that are highly contaminated by impulse noise. The proposed Detail Preserving Fast Median Filtering (DPFMF) technique is more effective in eliminating fixed value impulse noise and preserving the image details. The filter replaces a corrupted pixel by the median value of the fast ...

We prove that some important properties of convex subsets of vector topological spaces remain valid in the space of fuzzy numbers endowed with the Euclidean distance. We use these results to obtain a characterization of fuzzy number-valued Lipschitz functions. This fact helps us to find the best Lipschitz constant of the trapezoidal approximation operator preserving the value and ambiguity intr...

Green computing is the technological investigation where the system performance is optimized for achieving high performance computing in fewer amount of resource and power consumption. Therefore the presented work is an initiative for optimizing power consumption and performance enhancement by VM allocation and selection policies considering QoS expectations of the devices, which maximize the c...

The acuity of individuals’ approximate number system (ANS) is measured using a non-symbolic numerical discrimination task (e.g., Halberda & Feigenson, 2008) which is encapsulated by the Weber Fraction measure (Piazza & Dehaene, 2004). Children’s performance on this task is linked to symbolic arithmetic skills, standardized test scores and other long-term outcomes (e.g., Beddington et al., 2008;...

The talmudic maxim "to save one life is tantamount to saving a whole world" (Sanhedrin 37a) indicates that the value of human life is infinite. A fraction of infinity is stil infinity. Nothing in this world is of higher value or greater ethical import than human life. Even Torah commandments of the Holy One, blessed be He, must give way to the higher value of preserving human life. The biblical...

Making decisions based on relative rather than absolute information processing is tied to choice optimality via the accumulation of evidence differences and to canonical neural processing via accumulation of evidence ratios. These theoretical frameworks predict invariance of decision latencies to absolute intensities that maintain differences and ratios, respectively. While information about th...

Background Preference weights for EQ-5D-3L based on visual analogue scale (VAS) has recently been developed in Iran. The aim of the current study was to compare performance of this value set against the UK VAS-based value set.   Methods The mean scores for all possible 243 health states were compared using Student t test. Absolute agreement and consistency were investigated using concordance co...

Synthetic aperture radar (SAR) images are subject to prominent speckle noise, which is generally considered a purely multiplicative noise process. In theory, this multiplicative noise is that the ratio of the standard deviation to the signal value, the “coefficient of variation,” is theoretically constant at every point in a SAR image. Most of the filters for speckle reduction are based on this...

Abstract. An elementary but useful fact is that the numerator of the difference of two consecutive Farey fractions is equal to one. For triples of consecutive fractions the numerators of the differences are well understood and have applications to several interesting problems. In this paper we investigate numerators of differences of fractions which are farther apart. We establish algebraic ide...
