Four Field Motion Adaptive Deinterlacing Algorithm

Motion adaptive deinterlacing algorithm uses the advantages of intra field deinterlacing and inter field deinterlacing algorithms .Intra field interpolation algorithm is applied when the motion is present .The intra field methods are reconstructed the frame from the current field information .but this method introduce the edge flicker problems and jitter effect. Inter field interpolation algorithm applied when motion is not present. The inter field methods are depends on the previous and future fields for reconstruction of the current frame. This method introduces feathering effect. In this paper first two field and three field adaptive motion detection schemes are explained. The proposed method finds the motion using four field motion detection algorithm. It is most superior to two field and three field motion detection algorithms
