A novel de-interlacing technique based on phase plane correlation motion estimation

In this paper, a de-interlacing technique using motion compensated interpolation is proposed In the proposed scheme motion estimation is first performed between the same parity field i.e., reference and current field from either odd or even fields. Compared to other motion adaptive and motion compensated interpolation technique this method results in a better visual quality due to an accurate motion estimation technique. For further improvement a motion vector validation method based on motion parameters like pan, zoom or tilt is used to reduce the interpolation error caused due to the incorrect motion vector. Simulation results confirm that the proposed method has better visual performance compared to the conventional method.
