IMAGE COMPRESSION METHOD AND APPARATUS THEREFOR AND IMAGE RESTORING METHOD AND APPARATUS THEREFOR

摘要

A method and an apparatus for compressing an image, and a method and an apparatus for restoring an image are provided to encode a plurality of pictures by mutually referring to the pictures and improve compression efficiency. A method for compressing a picture includes a step of splitting each of a plurality of pictures into slices, a step of performing prediction on the slices corresponding to each picture to determine a high-efficiency prediction mode and a coding sequence for each slice, and a step of coding the slices according to the determined prediction mode and the coding sequence. The plurality of pictures is coded with reference to the plurality of picture.
