Discrete 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.
