High definition frame rate conversion

A hierarchical resolution image interpolator, comprising:

• an image reducer that provides a first lower image and a second lower image from a first image and a second image;
• a block-based motion estimator coupled to the image reducer that provides block-based motion vectors based on the first lower image and the second lower image;
• a motion vector selector coupled to the block-based motion estimator that provides pixel-based motion vectors based on the block-based motion vectors;
• a halo-reduction filter coupled to the motion vector selector that filters the pixel-based motion vectors to form filtered motion vectors;
• an occlusion-based adaptive interpolator coupled to the halo-reduction filter to provide for higher resolution motion vectors based on the filtered motion vectors;
• a high-resolution refiner coupled to receive high-resolution motion vectors related to the higher-resolution motion vectors and form refined motion vectors;
• a high-resolution halo-reduction filter coupled to the high-resolution refiner to further filter the refined motion vectors to form filtered refined motion vectors;
• and
• an interpolator coupled to the high-resolution halo-reduction filter, the interpolator providing an interpolated image between the first image and the second image based on the filtered refined motion vectors.
