Abstract

Optical flow is calculated for each sub-block on the basis of two images, the sub-blocks are then partitioned into a region having low confidence and a region having high confidence depending on the reliability of the optical flow, and the optical flow in the region having low confidence is filled by dilation processing using the optical flow in its surrounding regions.
