    摘要: Provided is a method of and apparatus for video encoding and decoding based on motion estimation. The method includes generating a motion vector by searching a reference picture using pixels of a current block, generating a prediction motion vector that is a prediction value of the motion vector by searching the reference picture using previously encoded pixels located adjacent to the current block, and encoding the current block based on the motion vector and the prediction motion vector. By accurately predicting the motion vector of the current block, the number of bits required for encoding the motion vector can be reduced, thereby improving the compression rate of video data.

    摘要: Provided are a method and apparatus for encoding and decoding based on intra prediction. The method of encoding based on intra prediction includes predicting a current block by searching for a pre-encoded area in a current picture using pre-encoded pixels adjacent to the current block, and intra prediction encoding the current block so that information indicating that the current block is intra predicted via the predicting of the current block is included. Accordingly, the compression rate of intra prediction encoding is increased even when the current block is not appropriately predicted by using a prediction value obtained from pixels adjacent to the current block.
