Claim 9:
10. An apparatus for reconstructing an optical flow by using artificial intelligence (AI), the apparatus comprising:
at least one processor configured to implement:
a bitstream obtainer configured to obtain feature data of a current residual optical flow from a bitstream for a current image; and
a prediction decoder configured to:
obtain the current residual optical flow by applying the feature data of the current residual optical flow to a neural-network-based first decoder,
obtain a second-order optical flow between a current predicted optical flow and a previous optical flow,
obtain the current predicted optical flow by modifying the previous optical flow according to the second-order optical flow, and
reconstruct a current optical flow based on the current residual optical flow and the current predicted optical flow.
