Image interpolation methodGaussian-Sinc functionpartition of unity propertyIn this paper,we propose a novel image interpolation method by using Gaussian-Sinc automatic interpolators with partition of unity property.A comprehensive comparison is made with classical image interpolation methods,such as the bicub...

also, Sinc function for interpolation points xk=kh is given by S(k,h)(jh)=δkj(0)=1,k=j,0,k≠j. So, S(k,h)∘ϕ(x) exhibits Kronecker delta behavior on the grid points xk=ϕ-1(kh)=a+bekh1+ekh and interpolation and quadrature formulas for f(x) over [a,b] are f(...
Figure 1: Possible multiplexing of sinc-shaped Nyquist pulses. The temporal and spectral features of sinc-shaped pulses bring benefits not only to optical communications but also to many other fields. Actually, sinc-shaped pulses correspond to the ideal interpolation function for the perfect restoratio...

Another technique of Lagrange interpolation polynomials (used as test functions) is not so much useful to determine the oscillating solution or problems with unbounded domains. A desirable use of sinc functions can deal with these adversities while keeping the experimental convergence rate. As the ...
