Method and apparatus for encoding and decoding using texture synthesis

A method and an apparatus for encoding and decoding an image using texture synthesis are provided to remove the temporal and spatial redundancy of a texture region included into an image efficiently, thereby improving the compression rate of the image encoding. A method for encoding an image comprises the following steps of: detecting a texture region in a current picture(410); selecting a part of the detected texture region as a sample texture for the synthesis of the texture region(420); and encoding the selected sample texture instead of the detected texture region(430).
