Method and apparatus for interpolating reference picture and method and apparatus for encoding/decoding image using same
The present disclosure relates to a method and apparatus for interpolating a reference picture and a method and apparatus for encoding/decoding a video using the same. The apparatus for interpolating the reference picture selects a plurality of filters for interpolating the reference picture and generates a reference picture having a target precision through a multi-stage filtering of the reference picture by using a plurality of filters. The compression efficiency of the video may be improved by interpolating a reference picture through the determination of a filter of a filter coefficient for interpolating the reference picture according to characteristics of the video and interpolating the reference picture through a multi-stage filtering or adaptively changing resolutions of motion vectors in the unit of predetermined areas.
