Abstract:
1. A method comprising: transforming individual image portions of a plurality of image portions of frames of a video signal from a spatial domain representation into a transform domain representation so as to generate a respective set of transform domain coefficients for each of the individual image portions; determining for at least one of the plurality of image portions a respective reference portion represented by a respective set of the transform domain coefficients, the respective set of the transform domain coefficients being arranged in a first order; determining for the at least one of the plurality of image portions a prediction of a target image portion based on the reference portion by predicting a non-translational motion of the target image portion relative to the respective reference portion, said predicting being based on: encoding the target image portion based on the prediction by generating an encoded bitstream that includes information about the non-translational motion.
