Methods for decoding and encoding image signals

Abstract

The invention relates to a method for decoding image signals, which includes the following steps: receiving the encoded image-complement stream of the image signal; generating an in-image prediction mode of the current encoded block in the encoded image based on a flag indicating whether the in-image prediction mode of the current encoded block is generated from the MPM candidate (most accurate prediction mode) of the current encoded block; By performing in-image prediction based on the generated in-image prediction modulation to create a prediction block for the current encoding block, the Invention also relates to a method for encoding image signals.
