Method and apparatus for encoding/decoding image based on intra prediction
Provided are an intra prediction-based encoding method, and an apparatus for accomplishing the same. In the method, a linear prediction coefficient of a current block is calculated based on encoded blocks adjacent to the current block, a predicted block is generated by performing intra prediction on the current block by using a linear prediction coefficient, and a residual block that is the difference between the current block and the predicted block is encoded. Accordingly, information regarding a direction of intra prediction does not need to be additionally transmitted, thereby reducing the amount of bits that are to be transmitted, and the quality of an image can be improved by adaptively controlling the efficiency and precision of intra prediction.
