Abstract
Motion estimation algorithms play a key role in picture-rate up-conversion. To realise high quality interpolated images, while keeping the processing requirements low, we anal- yse the following parameters of the motion estimation al- gorithm: The number of motion estimation iterations per input image pair and the image scanning order of individual iterations. Furthermore, we tackle the issue of the optimal selection of the motion vector candidates. The selected mo- tion estimation algorithm is the three-dimensional recursive search (3DRS) block matcher that offers a smooth and ac- curate motion vector field at relatively low computational cost.Keywords
