APPARATUS AND METHOD FOR CONSTRUCTING AND INDEXING A REFERENCE IMAGE

摘要

The present invention relates to an apparatus and method for constructing and indexing a reference image. The apparatus for constructing and indexing a reference image according to the present invention constructs and indexes a reference image so as to estimate a motion vector, wherein the apparatus comprises: a reference-image-constructing unit which interpolates the reference image to a variety of spatial resolutions and arranges a reference frame in accordance with the temporal position of the reference frame; and an index allocation unit which allocates a reference frame index in accordance with the temporal position of the reference frame.
