摘要：

In this paper we give a method, based on fast Fourier transform (FFT), to estimate the values of the signal samples between any two consecutive samples of an already sampled 2-D band-limited continuous signal. In other words, we increase the sampling rate from a lower rate and obtain the new samples at a higher rate. This will be useful when we want to store or transmit an image sampled at a lower rate and reconstruct it later with better quality. © 1990 IEEE
