Abstract: Disclosed herein are an inter prediction mode-based image processing method and an apparatus therefor. Specifically, a method for processing an image based on an inter prediction mode may include: generating a temporary candidate list by using a spatial neighbor block or temporal neighbor block of a current block; calculating a cost for each candidate in the temporary candidate list by using a template of the current block; generating a final candidate list by rearranging candidates of the temporary candidate list based on the calculated cost; decoding a merge index indicating a specific candidate in the final candidate list; and generating a prediction block of the current block by using motion information of a candidate indicated by the merge index.

Abstract: An image decoding method based on an inter prediction is disclosed. The image decoding method according to an embodiment of the present disclosure includes deriving first motion information of a current block by applying template matching on the current block; determining whether to perform the template matching in subblock units of the current block; if it is determined not to perform the template matching in the subblock units, generating a prediction block of the current block by using the first motion information; if it is determined to perform the template matching in the subblock units, deriving second motion information in subblock units by performing the template matching on a subblock of the current block; and generating a prediction block of the current block by using the derived first motion information and the derived second motion information. The template matching is a mode deriving motion information minimizing a difference value between a neighbor template region of the current block and a neighbor template region of a reference block of a reference picture.
