IMAGE CODING AND DECODING APPARATUS AND METHOD CONSIDERING HUMAN VISUAL CHARACTERISTICS

摘要

PROBLEM TO BE SOLVED: To provide an image coding and decoding method for effectively coding and decoding a region of interest using a plurality of rectangular regions when an image is coded and decoded.

SOLUTION: An image coding apparatus includes: a slice modeling unit which divides each image into at least one or more independent rectangular slices; an image header coding unit which codes information on positions and sizes of the slices divided by the slice modeling unit to an image header together with other information; and a slice coding unit which codes an image in units of slices by referring to the image header information.
