IMAGE ENCODING METHODS, IMAGE DECODING METHODS, IMAGE ENCODING EQUIPMENT, AND IMAGE DECODING EQUIPMENT

Abstract

The term refers to the method of encoding, the method of decoding, the device for encoding, and the device for decoding. The encoding method includes the following steps: dividing the image and determining the internal structural prediction mode of the chromatic component of the current encoding block; determining the prediction block of the chromatic component of the current encoding block according to the internal structural prediction mode of the chromatic component; and obtaining the refined prediction block of the chromatic component of the current encoding block by adjusting the prediction block of the chromatic component of the current encoding block.
