摘要： The present disclosure relates to an inter prediction method and apparatus using adjacent pixels, and a video encoding method and apparatus using the same. The inter prediction method for a predictive encoding includes: determining a current motion vector by estimating a motion of a current block; generating a reference block indicated by the current motion vector; calculating a motion compensation coefficient or an average compensation coefficient by using pixels neighboring the current block and pixels neighboring reference block; generating a changed reference block reflecting the motion compensation coefficient or the average compensation coefficient in the reference block; and determining the changed reference block as a predicted block of the current block. The present disclosure reduces a difference between an actual block and a predicted block by more accurately predicting the block to be encoded, thereby improving the compression efficiency.

摘要： A method of encoding a motion vector includes: selecting one of a plurality of predicted candidate motion vector sets by using motion information of neighboring blocks of a current block; selecting one of predicted candidate motion vectors within a selected predicted candidate motion vector set, as a predicted motion vector; encoding a differential motion vector representing a difference between a current motion vector or motion vector of the current block and a selected predicted motion vector; and encoding a predicted motion vector index indicating the selected predicted motion vector. As a motion vector is encoded after selecting an efficient predicted candidate motion vector set, the size of a differential vector to be encoded can be reduced without necessarily encoding additional information to indicate which set of predicted candidate motion vectors has been selected, resulting in improved compression efficiency of motion vectors and in turn the improved video compression efficiency.

摘要： A video encoding apparatus includes an intra prediction error collector; a transform base generator; an intra predictor; and a transform encoder, the intra prediction error collector collecting prediction errors of blocks having an equal intra prediction mode from macroblocks in a regular unit, which are encoded prior to a current macroblock, the transform base generator generating transform bases for respective intra prediction modes based on the prediction errors collected by the intra prediction error collector. Accordingly, the intra prediction encoding performance can be significantly improved with adding no addition information by adaptively generating a transform base according to an image characteristic change and transform-encoding an intra prediction error. As a result, the compression efficiency of a video compression apparatus or the picture quality of a reconstructed image can be greatly improved.
