IMAGE ENCODING / DECODING METHODS AND COMPUTER-BASED READ-AND-WRITING MEDIA FOR NON-INTERNAL STORAGE OF BIT STREAMS

Abstract

The invention relates to a method for image decoding / predicting. The image decoding method includes a step of determining the internal prediction mode of the current block, and a step of generating a prediction block of the current block, a method of performing prediction based on the internal prediction mode. When the internal prediction mode of the current block is matrix-based internal prediction mode (MIP), the length of the reference sample used for the internal prediction process is inferred from the length of the current block.
