AbstractDiscrete interpolation between successive samples of a sequence is often required in digital signal processing. In this paper, the subsequence approach for 1-D interpolation is extended to two dimensions to avoid redundant operations. Also an improved intermediate sequence is proposed to preserve the Hermitian symmetry in interpolating real valued signals. The resulting algorithm is very efficient and convenient because it permits the use of IFFT's with sizes that are the same as the corresponding forward transforms.
