ALIGNING A DISTORTED IMAGE

A method for determining an optimized weighting of an encoder and decoder network; the method comprising:for each of a plurality of test weightings, performing the following steps with the encoder and decoder operating using the test weighting:(a) encoding, using the encoder, a reference image and a distorted image into a latent space to form an encoding;(b) decoding the encoding, using the decoder, to form a distortion map indicative of a difference between the reference image and a distorted image;(c) spatially transforming the distorted image by the distortion map to obtain an aligned image;(d) comparing the aligned image to the reference image to obtain a similarity metric; and(e) determining a loss function which is at least partially defined by the similarity metric;wherein the optimized weighting is determined to be the test weighting which has an optimized loss function.
