PREDICTION IMAGE GENERATION METHOD, IMAGE CODING METHOD, IMAGE DECODING METHOD, AND PREDICTION IMAGE GENERATION APPARATUS

摘要

Provided is a prediction image generation method for generating a prediction image of a current block, the prediction image generation method including: an extraction step of extracting a plurality of first feature points each of which has a local feature quantity, the plurality of first feature points being included in a reconstructed image; a search step of searching a corresponding point from the plurality of first feature points, the corresponding point having a local feature quantity similar to a local feature quantity of a second feature point corresponding to the current block, a relationship between the corresponding point and the second feature point being expressed by information including a non-parallel translation component; and a generation step of generating the prediction image from the reconstructed image based on the relationship.
