Abstract

Algorithms for digitally processing sampled spatiotemporal signals typically ignore the fact that those samples were obtained time-sequentially, rather than instantaneously, at the beginning of each frame period The effect of displacing time-sequentially obtained samples to a non-time-sequential lattice is analyzed for both deterministic and nondeterministic signals Sample displacement is shown to cause unavoidable frequency-domain aliasing The resulting artifacts are compared in test signals that have been sampled with a lexicographic and bit-reversed ordering of the sample points
