Image processing method and device, network model training method and device, equipment and medium

The invention provides an image processing method, a network model training method and device, equipment and a medium, and relates to the field of image processing, in particular to the technical fields of computer vision, deep learning, image reconstruction and the like. According to the specific implementation scheme, a to-be-processed document is input into a pre-trained erasing network, first format characters in a to-be-processed document image are erased, and a final erased image corresponding to the to-be-processed document image is obtained; wherein the erasure network, the segmentation head network and the discriminator network form an erasure network model, and the erasure network is obtained by pre-training the erasure network model by using a sample document image pair; the sample document image pair comprises a sample document image and a label image which corresponds to the sample document image and is used for erasing the first format characters; the erasure network model is trained at least ac
