Abstract
Motion estimation is among the key techniques for a variety of problems in image sequence processing. Even for ideal conditions, when all temporal changes in the image sequence are solely due to motion, the performance of motion compensated prediction is limited by aliasing and quantization noise. This paper provides a theoretical framework for these impact allowing quantification of the power spectral density of the prediction error signal. Both aliasing and quantization are shown to have important impact for typical image sequences. As an illustrative example for an application of the findings, an adaptive in-loop filter for motion compensated prediction is designed. Improvements of up to 1 dB over a standard Wiener filter are demonstrated when the filter adapts on the local motion as suggested by the model calculation.
