Abstract
A method and system of hierarchical motion estimation include a reference frame and a current frame being downsampled, and the downsampled reference frame being stored. A coarse motion vector (MV) map is generated according to the downsampled reference frame and the downsampled current frame. Scan lines adjacent to a center scan line corresponding to a downsampled scan line in the downsampled reference frame are retrieved and then stored. A refined MV map is generated according to the coarse MV map, the current frame and the stored scan lines adjacent to the center scan line.
