A method for encoding for encoding a current image in an image set is disclosed that comprises accessing a reference image for the current image; determining at least one prediction image wherein a prediction image is obtained from a geometric transform applied to the reference image; said prediction image being a prediction for at least one region of current image; encoding the current image based on said at least a prediction image using block matching compensation of a coding standard; generating a bitstream comprising the encoded image, an item representative of the reference image and an item representative of the at least one geometric transform.
The determining of the at least a prediction image further comprises determining super-pixels for the current image; for each super-pixel of the current image, determining a super-pixel geometric transform between a super-pixel of the current image and a super-pixel of the reference image based on feature points belonging to the super-pixel of the current image; determining the at least one region of current image used for prediction and a geometric transform by merging the super-pixel geometric transforms.
