Abstract
Disclosed is a method for processing an image based on an inter prediction and an apparatus for the same. Particularly, the method may include generating a bi-directional predictor of each pixel of a current block by performing a bi-directional inter prediction based on a motion vector of the current block; deriving a first motion vector from a window area of a specific size in a first reference picture for a current pixel, and deriving a second motion vector from a window area of a specific size in a second reference picture for the current pixel; deriving a first predictor for the current pixel using the first motion vector, and deriving a second predictor for the current pixel using the second motion vector; and generating a third predictor of each pixel of the current block by performing a weighted sum of the first predictor and the second predictor.
