Paper Abstract

The use of interpolation filters in a motion estimator to realize sub-pixel shifts, may lead to unintentional preferences for some velocities over other. In this paper we analyze this phenomenon, focusing on the case of interlaced image data where the problem leads to the most pronounced errors. Linear interpolators, either applied directly or indirectly using generalized sampling are discussed. The conclusions are applicable to any type of motion estimator.
