The wide range of variations in human face due to view point, pose, illumination and expression deteriorate the recognition performance of the existing Face recognition systems. This paper proposes a new approach to face recognition problem using Legendre moments for representing features and nearest neighbor classifier for classification. The Legendre moments are orthogonal and scale invariant...

The closure conditions, which make a finite set of moment equations equivalent to the collisionless Boltzmann equation, are investigated for Gaussian and ellipsoidal velocity distributions working from the complete mathematical expression for the n-order stellar hydrodynamic equation, which was explicitly obtained depending on the comoving moments in a previous paper. First, for a Schwarzschild...

We propose a retrospective respiratory gating algorithm to generate dynamic CT studies. To this end, we compared three different methods of extracting the respiratory signal from the projections of small-animal cone-beam computed tomography (CBCT) scanners. Given a set of frames acquired from a certain axial angle, subtraction of their average image from each individual frame produces a set of ...

The goal of this paper is to give a form the operator involving generating function Apostol-Genocchi polynomials order α. Applying Korovkin theorem, we arrive at convergence with aid moments and central moments. We determine rate using several tools such as -functional, modulus continuity, second continuity. also type Voronovskaya theorem for estimating error. Moreover, investigate some results...

A new algorithm based on ESPRIT is proposed for the estimation of central angle and angular extension of distributed sources. The central angles are estimated using TLS-ESPRIT for both incoherently distributed (ID) and coherently distributed (CD) sources. For CD sources, the extension width is estimated by constructing a one-dimensional (1-D) distributed source parameter estimator (DSPE) spectr...

The first three statistical moments of the eluted band profiles from reversed-phase liquid chromatographic columns were attempted to be measured and analyzed in this work. And in this first part, the effect of the experimental conditions on the measurement accuracy of the third central moment is investigated. The optimized experimental condition is determined under which the measurement accurac...

Strain-induced gradients of local electric fields in semiconductor quantum dots can couple to the quadrupole moments of nuclear spins. We develop a theory describing the influence of this quadrupolar coupling on the spin correlators of electron and hole "central" spins localized in such dots. We show that when the quadrupolar coupling strength is comparable to or larger than the hyperfine coupl...

In this paper we obtain the central limit theorems, moderate deviations and the laws of the iterated logarithm for the energy Hn = ∑ 1≤j<k≤n ωjωk1{Sj=Sk} of the polymer {S1, . . . , Sn} equipped with random electrical charges {ω1, . . . , ωn}. Our approach is based on comparison of the moments between Hn and the self-intersection local time Qn = ∑ 1≤j<k≤n 1{Sj=Sk} run by the d-dimensional rando...

OBJECTIVE To compare the archwires inserted during the final stages of the orthodontic treatment with the generated moments at 0.018- and 0.022-inch brackets. MATERIALS AND METHODS The same bracket type, in terms of prescription, was evaluated in both slot dimensions. The brackets were bonded on two identical maxillary acrylic resin models, and each model was mounted on the orthodontic measur...
