摘要： Provided are a method and apparatus for encoding and decoding based on inter prediction. In the method of encoding based on inter prediction, image inpainting is performed by searching for at least one reference picture by using pixels that are adjacent to the boundary between a current block and a previously encoded region of a current picture and are included in the previously encoded region, and the current block is encoded based on a predicted block obtained as the result of performing image inpainting. Accordingly, it is possible to precisely generate a predicted block, thereby improving the compression rate of image encoding.
