Isotropic Kernels for Two-Dimensional Image Interpolation
The paper proposes a technique of the composition of two-dimensional interpolation kernels possessing the approximately isotropic spectral characteristics. The application of these kernels makes it possible to weaken many artifacts that appear at interpolation procedures implemented by the traditional techniques. The paper presents the results of the mathematical simulation that confirm the advantages of the proposed technique.
