Classification: CPC G | IPC G

Claim 12:
13. A system comprising:
at least one storage device storing a set of instructions; and
at least one processor in communication with the at least one storage device, when executing the stored set of instructions, the at least one processor causes the system to perform operations including:
obtaining a first image of a first modality and a first resolution;
generating a second image of a second modality and a second resolution by processing, based on a trained machine learning model, the first image;
wherein the second modality is different from the first modality, the second resolution is different from the first resolution,
the trained machine learning model is a generative adversarial network (GAN) and includes a generative model, a first discriminative model, and a second discriminative model, and
in a process of training the machine learning model, the first discriminative model is used to evaluate a difference between a predicted image of the generative model and a reference image, the reference image is a desired predicted image, and the second discriminative model is used to evaluate a difference between at least one first shape extracted from the predicted image of the generative model and at least one second shape extracted from a sample input image of the generative model.
