In recent years, iris recognition has become a popular recognition system as compare to the existing systems. It is an important biometric method for human identification with high accuracy. It is the most reliable and accurate biometric identification system available today. The most popular biometric types are: signature, face, iris, finger prints, hand and voice. Among all these biometric te...

A novel cross term deleted Wigner representation can be obtained by expanding the Wigner Distribution (WD) in terms of two complementary Gabor coe cients of the signal and a translated set of Wigner basis functions. Two such complementary Gabor coe cients of a signal can be obtained by reversing the role of Gabor synthesis window h(t) and its biorthogonal function b(t). Such a representation is...

Abstract. Given a biorthogonal pair of multi-resolution analyses on the interval, by integration or differentiation, we build a new biorthogonal pair of multiresolution analyses. Using both pairs, isotropic or, as we focus on, anisotropic divergence-free wavelet bases on the hypercube are constructed. Our construction generalizes the one from [Rev. Mat. Iberoamericana, 8 (1992), pp. 221–237] by...

We will be concerned with the solution of an elliptic boundary value problem in one dimension with polynomial coeecients. In a Galerkin approach, we employ biorthogonal wavelets adapted to a diierential operator with constant coeecients, and use the reenement equations to set up the system of linear equations with exact entries (up to round-oo). For the solution of the linear equation, we const...
