An image interpolator for high-definition images is presented that utilizes a two or more level hierarchical decomposition for complexity reduction. At the lowest level, after a block-based motion estimator, a pixel-based motion vector selector and a motion vector-based halo reducer, an occlusion-based adaptive motion field interpolator provides preliminary motion vectors for higher resolution level. At the high resolution level, a new motion estimation refining based on the double consideration of eventual occlusion region and motion vector precision refines the preliminary motion vectors, and again a motion vector-based halo reduction re-corrects the refined motion vectors. A new motion compensated image interpolator with controllable features for multiple interpolated images is presented. A versatile post-processing configuration for remaining artifacts may also be included.
