1. A method for processing images, comprising:
providing a set of initial first images, each initial first image presenting a respective subject according to a first style X, the first style X including one or more first visual features;
providing a set of initial second images, each initial second image presenting a respective subject according to a second style Y, the respective subjects of the initial second images being different from the respective subjects of the initial first images, the second style Y including one or more second visual features that are different from the one or more first visual features of the first style X;
implementing a first generator G in a computer processing system to produce a set of generated first images based on the set of initial first images;
implementing a second generator F in the computer processing system to produce a set of generated second images based on the set of initial second images; and
implementing one or more training functions to train the first generator G and the second generator F based on the generated first images and the generated second images, such that: (i) each generated first image produced by the first generator G presents the subject of a respective one of the initial first images according to the second style Y, and (ii) each generated second image produced by the second generator F presents the subject of a respective one of the initial second images according to the first style X.
