Abstract
This paper introduces a new method for the interpolation that has to be performed when motion estimation and compensation are applied to interlaced sequences with subpel accuracy. It is based on the assumption that a uniform motion exists between two successive frames. The exact formulas for the estimation are derived. They show that in order to obtain a correct interpolation of each field of one frame, it is necessary to use the information of both fields of this frame. Because the ideal filters have infinite impulse responses, the filter design is discussed, and the efficiency is measured for typical sequences
