Abstract: The present invention provides a method for decoding a video signal on the basis of an optical flow motion vector, comprising the steps of: when a bi-directional prediction is performed for a current block, acquiring a gradient map corresponding to the current block, wherein the gradient map represents a set of gradients at all pixel positions within a block having a larger size than the current block, and each gradient includes an X-axis gradient component and a Y-axis gradient component; determining an optical flow motion vector by applying a weight factor to the X-axis gradient component and the Y-axis gradient component; acquiring an optical flow predictor on the basis of the optical flow motion vector; and reconstructing the video signal by using the optical flow predictor.
