摘要

Provided are training method for descreening system, descreening method, device, apparatus and medium. The training method for descreening system comprises: obtaining a first error function based on a halftone position and a preset label value, obtaining a second error function based on simulation images and non-halftone training samples, obtaining a third error function and a fourth error function according to a discrimination result, obtaining a fifth error function according to feature A and feature B, and based on the characteristics of Generative Adversarial Networks, according to the second error function, third error function, fourth error function and fifth error function, the sixth error function and seventh error function are respectively obtained, then an error function is constructed according to the errors generated by training, and the network parameters of each part of the models in the descreening system are updated by backpropagation of error function.
