METHOD AND APPARATUS OF PERFORMING INTRA PREDICTION USING ADAPTIVE FILTER

摘要

PURPOSE: An image decoding method for intra-prediction using an adaptive filter and a computer-readable recording medium are provided to implement the intra-prediction with applying the adaptive filter to a predicted block and a peripheral pixel value when encoding an image. CONSTITUTION: A method for implementing intra-prediction using an adaptive filter includes: a step (201) of determining whether or not applying the filter to a referential pixel value; a step (202) of applying the filter to the referential pixel value according to the determination of applying the filter to the referential pixel value; a step (S203) of implementing the intra-prediction based on applying the filter to the referential pixel value; a step (S204) of determining whether or not applying the filter to a prediction value by each prediction mode; and a step (S205) of applying the filter to the prediction value according to the determination of applying the filter to the prediction value.
