Sampling reconstruction of N-dimensional band-limited images after multilinear filtering
Jerram L. Brown, K. Sa-ngsari · IEEE Transactions on Circuits and Systems · 1989
The generalized sampling expansion of A. Papoulis (1977) for a multichannel configuration is investigated for the case where the bandlimited input depends on N real-variables t/sub 1/,. . .,t/sub V/ and is used as a common input to a parallel bank of m independent N-dimensional linear shift-invariant filters. The input is assumed to have its N-dimensional Fourier transform bandlimited to the frequency range mod omega /sub i/ mod>
