METHOD AND APPARATUS FOR ENCODING AND DECODING BASED ON INTRA PREDICTION

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.
