DESCREENING SYSTEM TRAINING METHOD AND APPARATUS, DESCREENING METHOD AND APPARATUS, DEVICE, AND MEDIUM

摘要

Disclosed are a descreening system training method and apparatus, a descreening method and apparatus, a device, and a medium. The descreening system training method comprises: acquiring a first error function based on a screen pattern location and a pre-set tag value; acquiring a second error function based on a simulated picture and training samples without screen patterns; acquiring a third error function and a fourth error function according to a discrimination resu acquiring a fifth error function according to a feature A and a feature B; based on the characteristics of a generative adversarial network and according to the second error function, the third error function, the fourth error function and the fifth error function, respectively acquiring a sixth error function and a seventh error function; and then constructing an error function according to an error generated by training, and using the error function to carry out back propagation and update on network parameters of each model part in a descreening system. The descreening system removes multiple error factors affecting the descreening effect of the descreening system in a descreening system training process, so that the descreening effect of the descreening system is relatively good.
