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： The present disclosure provides an encoding/decoding method using a tree structure. The encoding method for encoding image information includes: grouping predetermined areas having the image information into a plurality of groups, and generating a node value of each layer up to an uppermost layer by determining a minimum value or a maximum value of information to be encoded within grouped areas as information on the grouped areas; and encoding a difference value between the node value of each layer and a node value of an upper layer or a difference value between the node value of each layer and a value determined based on a preset criterion. Accordingly, the encoding efficiency and in turn the video compression efficiency are improved by using the tree structure in the encoding of various pieces of image information and the decoding of the resultant encoded data.
