Abstract
Disclosed herein are a method and apparatus for image encoding and image decoding using region segmentation. A picture is divided into multiple sub-pictures, and encoding and/or decoding are performed on the multiple sub-pictures resulting from division. Encoding operations and/or decoding operations on the sub-pictures may be independently performed. Merging and filtering are applied to reconstructed sub-pictures generated by decoding, and a reconstructed picture is generated after processing of merging and filtering.
