Definitions

  • the present disclosure relates to a method for generating coded motion information before reconstructing by using motion information merge, and video encoding apparatus and a video decoding apparatus for encoding and decoding images by using the same.
  • the determination as to whether the motion vectors are similar may be made by determining whether distances between the motion vectors of the neighboring blocks included in the group of merge-decision blocks are smaller than predetermined threshold value information.
  • the distance between the motion vectors may use a two-dimensional Euclidean distance or a city-block distance.
  • the determination as to whether the pieces of the motion information are similar to one another may be made by using a part of information among the pieces of the motion information, for example, by using only the motion vector.
  • the determination as to whether the pieces of the motion information are similar to one another may be made by additionally determining whether the reference frames of the motion information are equal to one another. That is, when the reference frames as well as the motion vectors are equal to one another, it can be determined that the pieces of the motion information are similar to one another.
