Paper Abstract

Incorporating spatiotemporal jitter into the scanning of time-varying imagery on a rectangular lattice effects the severity of baseband noise under the conditions of sampling at or below the Nyquist rate. Sampling spatiotemporal images on a hexagonal lattice has been shown to provide a 13.4% reduction in the sample rate over that of a comparable rectangular system. The relationship between the increased performance due to sampling on a hexagonal lattice and the performance degradation due to the presence of jitter in the scanning process is investigated in this paper. Spatiotemporal pixel jitter is included in the scanning of time- varying imagery on a hexagonal grid. The aliasing noise is dependent on the statistical properties of the jitter as well as the pattern used to scan the image. The signal-to-aliasing noise power ratio is used as a performance measure.
