METHOD FOR ENCODING AND DECODING IMAGE, AND APPARATUS FOR ENCODING AND DECODING IMAGE

摘要

A method of encoding an image, a method of decoding an image, an apparatus for encoding an image and an apparatus for decoding an image are provided. The method of encoding an image includes dividing an image into a plurality of partition images and adding an expanded image to each of the partition images, the expanded image including at least parts of some of the partition images; and encoding the partition images. Therefore, it is possible to prevent the deterioration of the picture quality along the boundaries between a plurality of partition images of an ultra high-definition (UHD) image.
