Motion compensated de-interlacing and motion estimation based on Yen's generalisation 1 of the sampling theorem (GST) have been proposed by Delogne 2 and Vandendorpe. 3 Motion estimation methods using three-fields have been designed on a block-by-block basis, minimising the difference between two GST predictions. We will show that this criterion degenerates into a two-fields criterion, leading to erroneous motion vectors, when the vertical displacement per field period is an even number of

We provide a solution for this problem, by adding a term to the matching criterion. , Telephone: +31 (0) 40 2745356 * Note that the coefficients H o (z) and H e (z) are the weighting factors corresponding to the odd and the even contributions to the even lines F e (z, n) in Eq. (8). Nevertheless, one should not interpret them as the odd or even coefficients, as this interpretation would not hold for the odd lines F o (z, n) in Eq. (10).
