Abstract

Aliasing noise can be controlled in time-varying imagery by the inclusion of spatiotemporal jitter in the scanning process and/or by the appropriate choice of a scanning pattern. A three-dimensional nonseparable model for jittered sampling is derived by taking into account the periodicity of the spatiotemporal sampling function and the time to scan each picture element. From the use of this model, the severity of aliasing noise can be predicted by the proper choice of the jitter random variables and the pattern used to obtain the image samples. The signal-to-aliasing-noise power ratio is used as a performance measure. Aliasing noise reduction is analyzed for different scanning patterns with and without spatiotemporal jitter.
