Claim 0:
1. A method, executed in an electronic device, for high-resolution image manipulation, the method comprising:
obtaining an original high-resolution image to be manipulated, and a driving signal indicating a manipulation;
down-sampling the original high-resolution image to obtain a low-resolution image to be manipulated;
generating, from the low-resolution image based on the driving signal using a trained manipulation generator, a low-resolution manipulated image and a motion field, the motion field representing pixel displacements of the low-resolution image to obtain the manipulation indicated by the driving signal;
computing, from the original high-resolution image, a high-frequency residual image;
generating, using the motion field and the high-frequency residual image, a high-frequency manipulated residual image; and
outputting, as a high-resolution manipulated image, a combination of at least the high-frequency manipulated residual image and a low-frequency manipulated image, the low-frequency manipulated image being generated from the low-resolution manipulated image by up-sampling.
