1. A method of decoding an image, the method comprising:
obtaining global motion information;
generating, on the basis of the global motion information, a warping region; and
generating a corrected warping region by correcting a pixel value of the pixel within the warping region using neighboring pixels,
wherein the pixel value of the pixel within the warping region is corrected by using the global motion information and a gradual difference between values of the different neighboring pixels adjacent to the pixel within the warping region.
