Delogne et al. (see IEEE Transactions on Image Processing, vol.3, no.5, p.482-91, 1994) have shown how the motion estimation and compensation have to be carried out when interlaced images are processed under the assumption of a translational motion. Due to the finite accuracy of the motion vectors, the prediction error is nonzero after motion compensation. We therefore investigate the influence of quantizing the motion vectors on the statistical properties of the prediction error signal. The power spectral density and the variance of the prediction error are also computed
