A real-time method of multidimensional interpolation based on the generalized real discrete Fourier transform (GRDFT) is presented. By factorizing the 1D transform matrix into the preprocessing and postprocessing matrices, and approximating the postprocessing stage such that any degree of desired accuracy is obtained, increased speed of computation and feasibility of electro-optical or VLSI implementation at reduced cost are achieved.
